Option 3 : Adulterated cement changes its colour after heating it to high temperature. Free 10 Questions 10 Marks 6 Mins Concept: Adulterated cement
Adulteration of cement is characterized as the addition of extra components to the cement that results in observable changes such as color, texture, strength, and other properties, as well as unobservable modifications with macro elements and metals.
The adulteration of quality cement is one of the major causes of structural failure and these are added to cement:
- To reduce the margins of cost.
- To decrease the quality of cement.
- Decreasing quality results in weaker bonding between their particles.
The preliminary test for cement analysis for adulteration is listed as:
- Color test
- Fine Test
- Smell test
- Presence of lumps
- Temperature test
- Heat test
- Float Test
- Shape/ Performance Test
- Strength Test
Heat test
- Take 1 gm of the sample, heat it for about 20 minutes on a steel plate. And note done the observation.
- In the case of adulterated cement, the sample changes its color. But in the case of un-adulterated cement, it retains its color.
