The Full Story – Cement is a widely used building material. Whether you use it on the job, are having some cement work done at your home, or planning a do-it-yourself project, it’s important to know what cement can do if you come into direct contact with it.
Cement is available in many different products for commercial and home use. It is available in pure powder form or in premixed forms such as concrete (cement and aggregate ), mortar (cement and sand), and grout (a more fluid form of cement). These different cement products have specific purposes. For example, you would use grout to fill spaces between tiles and mortar to bond bricks together.
Cement can cause caustic injury, resulting in chemical burns of any part of the body it comes in contact with – skin and eyes, mouth and throat if swallowed, and lungs if cement powder is inhaled. Cement is largely made up of calcium oxide. When it reacts with water, it produces highly alkaline (high pH) calcium hydroxide that can reach a pH of 12 or higher within a couple of minutes.
- This is why dry cement is less caustic than wet cement.
- Remember that the pH tells us how acidic or alkaline a solution is on a scale of 0 (most acidic) to 14 (most alkaline), with a neutral pH being about 7.
- So, because the pH of wet cement is so high, it can cause burns.
- Some of the worst outcomes occur when cement gets into or seeps through boots, gloves, or clothing.
By the time the person is aware of this, significant burns to the skin could have already occurred. The longer the cement stays on the skin, the more damaging the burn can be. Even after washing the cement off, the alkaline burn usually gets worse before it gets better.
In severe cases of cement burn of the skin, the burn can extend deeper into tissues beneath the skin to damage muscle and even bone. Other skin problems can also occur from cement. It’s gritty and contains chemicals that can cause dermatitis characterized by redness, swelling, and itching. Swallowing cement can cause burns of the lips, mouth, throat, and stomach.
Initial signs can include drooling, difficulty swallowing, or vomiting. In some cases, cement can harden in the gastrointestinal tract and cause obstruction. Inhaling cement dust can cause coughing, wheezing, and difficulty breathing. The best prevention is to avoid or limit contact with cement.
Keep cement out of reach and sight of children and pets. Never transfer cement products out of their manufacturer’s containers into unmarked containers. Read and follow the manufacturer’s instructions for use. Wear appropriate personal protective equipment such as well-fitting gloves, masks, and boots when working with cement products.
If you inhale cement dust, move away from it and seek fresh air immediately. Upon contact with cement, remove contaminated clothing right away. If cement is on your skin or eyes, rinse it off immediately with cool or room temperature water for at least 15 minutes.

What would happen if you eat cement?
Outlook (Prognosis) – How well a person does depends on the amount of poison swallowed and how quickly treatment is received. The faster a person gets medical help, the better the chance for recovery. Swallowing or putting small amounts of rubber cement in your mouth is often harmless.
Can you get sick from cement?
Abstract – Even in the 21st century, millions of people are working daily in a dusty environment. They are exposed to different types of health hazards such as fume, gases and dust, which are risk factors in developing occupational disease. Cement industry is involved in the development of structure of this advanced and modern world but generates dust during its production.
Cement dust causes lung function impairment, chronic obstructive lung disease, restrictive lung disease, pneumoconiosis and carcinoma of the lungs, stomach and colon. Other studies have shown that cement dust may enter into the systemic circulation and thereby reach the essentially all the organs of body and affects the different tissues including heart, liver, spleen, bone, muscles and hairs and ultimately affecting their micro-structure and physiological performance.
Most of the studies have been previously attempted to evaluate the effects of cement dust exposure on the basis of spirometry or radiology, or both. However, collective effort describing the general effects of cement dust on different organ and systems in humans or animals, or both has not been published.
Why is cement poisonous?
Abstract – Cement and concrete are products used widely in the construction sector, with a traditional perception that any hazards that they have are limited to dermatitis in a small number of workers. In some cases, employers and builders do not think that concrete is a chemical.
- However, contact dermatitis is one of the most frequently reported health problems among construction workers.
- A review of the available literature suggests that cement has constituents that produce both irritant contact dermatitis and corrosive effects (from alkaline ingredients such as lime) and sensitization, leading to allergic contact dermatitis (from ingredients such as chromium).
These findings indicate that cement and concrete should be treated as hazardous materials, and that workers handling such products should reduce exposure wherever possible. Initiatives to reduce the chromium content of cement have been shown to be successful in reducing the incidence of allergic dermatitis, although the irritant form remains.
Can stomach acid eat through concrete?
A cascade of corrosive stomach contents creates continual color conversion in concrete! – Image via Wikipedia Most people don’t consider the fact that the fluids in their stomach are corrosive, but that’s how the body digests things. And when someone loses their lunch on concrete, the can actually etch the surface.
- Sidewalk Stain Before Pressure Washing If the lunch included something colorful – like beets or wine – the stomach acid can actually convey that coloring into the concrete itself and leave a nasty permanent stain.
- If the discharge is free of any staining color, the stomach acid can sometimes clean the surface of the concrete.
Then we have to apply brighteners around the stain to keep it from standing out. Cleaning the mess up quickly is the only way to avoid discoloration. And because we got right to it, our client avoided a stain and kept their store owners happy. Sidewalk Stain After Pressure Washing Many stains can’t be removed if you wait too long.
Grease, oil and hydraulic stains on driveways will usually come right out if we get to it within 24 hours. Concrete is porous like a sponge and the longer you wait to treat the stain, the deeper it soaks in. So if you have a stain that you want us to pressure wash off your sidewalks, driveway, or other surfaces – call us before is sets in and can’t be removed.

How do I stop eating clay?
– If you want to stop eating dirt, or your cravings bother you and cause distress, these tips may be helpful:
Talk to a trusted friend or family member. If you tell someone you trust about your cravings, they may be able to offer support and help distract you if you have a hard time avoiding dirt on your own. Chew or eat food that’s similar in color and texture. Finely ground cookies, cereal, or crackers could help alleviate your cravings. Chewing gum or sucking on hard candy can also help with pica cravings. Speak with a therapist. If you aren’t sure why you’re craving dirt, a therapist can help you address the cravings and explore behaviors that can help you avoid eating dirt. See your healthcare provider. You might want to eat dirt because you aren’t getting the right nutrients. If you do have any nutrient deficiencies, your doctor can help you correct these imbalances. If you’re getting enough of the vitamins you need, the cravings might go away. Use positive reinforcement. A system of rewards for not eating dirt can also help some people dealing with pica cravings. Being rewarded for choosing a food item can help reduce your desire to eat dirt.
Is pica a disease?
What Is Pica? – Pica is an eating disorder in which a person eats things not usually considered food. Young kids often put non-food items (like grass or toys) in their mouths because they’re curious about the world around them. But kids with pica (PIE-kuh) go beyond that. Sometimes they eat things that can lead to health problems.
What are the 3 types of pica?
Causes and symptoms – Pica in humans has many different subgroups, defined by the substance that is ingested. Some of the most commonly described types of pica are eating earth, soil, or clay (geophagia); ice (pagophagia); and starch (amylophagia). However, pica involving dozens of other substances, including cigarette butts and ashes, hair, paint chips, and paper have also been reported.
pregnancy developmental disabilities mental retardation psychiatric disease and autism early childhood (under age three) poor nutrition or low blood levels of iron and other minerals certain cultural or religious traditions
How do you remove pica?
– Your doctor will probably begin by treating any complications you’ve acquired from eating nonfood items. For example, if you have severe lead poisoning from eating paint chips, your doctor may prescribe chelation therapy, In this procedure, you’ll be given medication that binds with lead.
- This will allow you to excrete the lead in your urine.
- This medication may be taken by mouth, or your doctor may prescribe intravenous chelation medications for lead poisoning, such as ethylenediaminetetraacetic acid (EDTA).
- If your doctor thinks your pica is caused by nutrient imbalances, they may prescribe vitamin or mineral supplements.
For example, they’ll recommend taking regular iron supplements if you’re diagnosed with iron deficiency anemia. Your doctor may also order a psychological evaluation to determine if you have OCD or another mental health condition. Depending on your diagnosis, they may prescribe medications, therapy, or both.
Why is my kid eating dirt?
What is pica? – Pica is a compulsive eating disorder in which people eat nonfood items. Dirt, clay, and flaking paint are the most common items eaten. Less common items include glue, hair, cigarette ashes, and feces. The disorder is more common in children, affecting 10% to 30% of young children ages 1 to 6.
Is dry cement toxic to humans?
Toxicological Effects Irritation/Corrosion: Skin: Dust may cause skin irritation. Eyes: Dust may cause eye irritation. Respiratory: Dust may cause respiratory tract irritation when cutting or grinding. Sensitization: Dust may cause sensitization due to the potential presence of trace amounts of hexavalent chromium.
Is cement harmful to skin?
Skin irritation – Causes & treatment – Irritation is caused by the skin’s exposure to concrete and, more specifically, its aggregate material makeup. This is because concrete includes a binder ingredient called Portland cement, which is also found in mortar, plaster, grout, and more.
- When wet, uncured Portland cement reaches caustic pH levels of 12 or higher, compared to the skin’s pH scales, which range between 4-7.
- Contact with this high pH can lead to a chemical reaction, with the potential to cause severe chemical burns to the skin or worse.
- Quick note: pH is a measure of how acidic or alkaline a solution is on a scale of 0-14 (most acidic to most alkaline).
Washing with soap and water as soon as contact occurs can prevent worsening skin issues and damage.
Is cement water toxic?
Wet Cement Injury Investigations – Concrete contains cement as a primary ingredient, along with water, coarse aggregate such as stone, and fine aggregate such as sand. Fresh wet cement dries and forms concrete which is easy to work with, versatile, durable, and economical.
It is used by thousands of workers on construction sites and by do-it-yourselfers on residential projects. The hazards of wet cement are subtle and injuries from exposure to wet cement are often delayed. HAZARDS ASSOCIATED WITH WET CEMENT When cement is dry it contains calcium oxide, which is not particularly dangerous.
However, when water is added to cement, calcium hydroxide is formed, which is extremely alkaline with a pH of 12 to 13. Normal human skin has a pH of 5.5; therefore, wet cement is a “hazardous chemical” because it can produce alkaline (caustic) burns to the skin and eyes which progress and get worse without additional exposure. A worker may have wet cement on his or her skin for hours without feeling any discomfort; however, the chemical action is damaging the skin microscopically. By the time a worker becomes aware of a burn injury, much damage has already occurred and further damage is difficult to stop.
Wet cement burns may result in blisters, dead or hardened skin, or black and green skin. In severe cases, these burns may extend to the bone and cause disfiguring scars or disability. HAZARD CONTROL Direct skin contact with wet cement can be effectively controlled by the use of proper personal protective equipment (PPE) such as clothing which includes wearing waterproof gloves, long-sleeved shirt and long pants.
If it is necessary to stand in fresh wet cement while it is being placed, screeded, or floated, workers should wear rubber boots. Boots should be high enough to prevent wet cement from getting into them.Clothing worn as protection from fresh wet cement should not be allowed to become saturated with moisture because saturated clothing can transmit alkaline or hygroscopic effects to the skin.
If powdered Portland cement or liquids containing Portland cement penetrate through the clothing, the clothing should be immediately removed and the exposed skin washed using soap or mild detergent and water.Additional controls include following proper work practices and the hazard information found in Material Safety Data Sheet (MSDS; currently referred to as Safety Data Sheets (SDS)).
Safe-use information found in warning labels on delivery tickets and other literature should be properly communicated to product users. Studies have demonstrated that the risk of injury from the hazards of wet cement is beyond the knowledge or awareness of many ordinary users, absent adequate warnings about those hazards and the risk of injury.
Can cement cause an infection?
Cement sepsis is an infection and inflammation resulting from dental cement being around the crown abutment margin. The body doesn’t like the rough surface as it harbors bacteria. Since the body can not expel it, bone resorbs as an attempt to get away.
If we do not treat cement sepsis it is very possible that the dental implant will fail. Cement sepsis is fairly common. Many dentists have figured out ways to completely avoid this complication and probably never cause this, others well not so much. Dentists are going to see a lot of it if they use stock abutments and poor techniques to cement their dental crowns.
If a dentist is going to cement a crown (they can be screw retained), then the steps found on the cement dental crown post should be followed.
Can stomach acid break down cement?
Can stomach acid dissolve concrete? – Stomach acid has the power to break through layers of concrete and break down the components that make it such a durable, strong material. Certain coloured foods such as wine or beets can even discolour and stain concrete.
