Cement Mortar Ratio For Brickwork – Consider the following scenario: The wall’s length is 3 meters, its breadth is 2 meters, and its thickness is 0.23 meters. Brickwork Volume = 9 x 5 x 0.23 = 10.35 m3 We know that 1 m3 of brickwork requires 500 no. So, with the brickwork of 10.35 m3, 500 x 10.35 = 5175 Nos.

- Also, keep in mind that 1 m3 of brickwork requires 0.3169 m3 of mortar.
- As a result, for 10.35 m3 of brickwork, the formula is 0.316910.35 = 3.28 m3.
- Now, let’s figure out how much cement and sand are in the mortar.1:4 Mix Ratio Consider a 1:4 mortar mix ratio.4 parts sand, 1 part cement 1+4 = 5 parts in total 1.

Concrete (bags) 2.1/5 x Cement (volume of mortar) = a fifth of a third of a third of a third of a third of (volume of 1 bag of cement = 0.035 m3) = 0.656 m3 = 0.656/0.035 = 0.656/0.035 = 0.656/0.035 18.74 bags of cement = 19 bags of cement 2. Sandbags (cu.

### How much sand and cement do I need for 1m3 brick?

Ans. :- 9 cu ft or 0.26m3 of sand quantity are required for 1 cubic metre of brickwork by taking mix ratio 1 part cement to 6 parts of sand.

## How many bags of cement is 1m3?

So, approximately 11 bags cement are used in M25 grade of 1m3 concrete.

## How many bags of cement do I need for 1000 bricks?

Cement id use a 4/1 mix. if i remember correctly 40 bags make a ton, so around 10 bags should be ok.

### How do you calculate 1m3 concrete cement?

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

## How many m3 are in 1 bag of cement?

A cement bag contains 0.035 cubic meters of cement by volume.

### What is the volume of 1 bag cement?

Calculate the Volume of a Cement Bag in Cubic Feet – The cubic feet is the second method to calculate the volume of a cement bag. But before moving to the calculation check, how much does C.ft. actually, mean? Don’t be one of those who won’t know about the cubic feet.

- ∴ Number of cement bags = 1440 (kg/m³)/50 (kg)
- ∴ Number of cement bags = 28.8 91/m³
- By this, we know the total number of bags in one cubic meter.

Here, one metric cube (1 m³) is equal to 35.314 Cubic feet. Now, it can be: 1 = 35.314 (C.ft/m³) Thus, 35.314 (C.ft/m³) = 28.8 (1/m³) ∴ Volume of 1 cement bag = 35.314 C.ft / 28.8 ∴ Volume of 1 cement bag = 1.22 C.ft. Therefore the volume of 1 cement bag is 1.22 cubic feet. So, that’s how you can calculate the volume of a cement bag. Now, let’s take one more method into account:

## What is 1m3 of cement?

1 Cubic Meter of Concrete 1m 3 of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates.

#### How many cement bags are in a brick?

There are several things upon which the requirement of cement bags differ like structure, thickness, ratio of materials that are to be used in the construction, type of cement. But without knowing how many cement bags required for 1500 sq ft house, you won’t be able to place your order.

- Thumb rule for cement in rcc concrete is 0.301 cement bags/sq ft
- Thumb Rule for cement bags in surface ground is 0.089 cement bags/sq ft
- Thumb Rule for cement bags in external wall brickwork is 1.26 cement bags/m3 of brickwork of 9 inch
- Thumb Rule for cement bags in internal wall brickwork is 1.28 cement bags/m3 of brickwork of 4.5 inch
- Thumb Rule for cement bags for external plastering is 0.170 cement bags/ sq ft plastering
- Thumb Rule for cement bags for internal plastering is 0.008 cement bags/ sq ft plastering
- Thumb Rule for cement bags for ceiling plastering is 0.005 cement bags/ sq ft plastering

Now if you are planning to use cement bags for 1500 sq feet house then to know how many bags you need to buy, follow this calculation:

Cement required by the external brick wall: External brick wall length =2(50+30) = 160 ft

Height of brick wall 10 feet Height of brick wall above roof slab = 3feet Depth of brick wall = 2 feet Total Height= 15feet Area of external brick wall= 160* 15= 2400 sq ft Volume = 2400 sq ft* 9 inch = 1800 cu ft Volume = 1800/ 35.3147 = 51m3 Volume of brickwork = 51m3 Now let’s observe the above mentioned rule for wall brickwork: Thumb Rule for cement bags in external wall brickwork is 1.26 cement bags/m3 of brickwork of 9 inch(cement:sand=1:6) No of cement bags= 51*1.26= 64bags

Cement required by internal brick wall

Brick wall length = 50+30+30+30 =140 ft Height of Brick wall =10 feet Depth of brick wall = 2 feet Total height = 12 feet Area of external brick wall = 140* 12= 1680 sq ft Volume = 1680 sq ft * 4.5 inch= 630 cu ft Volume = 630/35.3147 =17.84m3 Volume of brick work = 17.84 Thumb Rule for cement bags in internal wall brickwork is 1.28 cement bags/m3 of brickwork of 4.5 inch(cemet: sand= 1:4) No of cement bags = 17.84* 1.28= 23 So the total number of bags becomes 64+23= 87 This is the approx amount of cement bags you will be needing.

## How many blocks can 1 bag of cement?

How to Estimate the Quantity of Sand and Cement Required for Moulding Blocks In Nigeria, the 9 inches hollow block (450mm x 225mm x 225mm) is normally used for the construction of blockwork of buildings exceeding one storey. The length of the block is 450mm (18 inches), the height is 225mm (9 inches), and the width is 225mm (9 inches).

- Contractors and builders are often faced with the challenge of either buying blocks for construction or moulding it on their own.
- When the conditions are right, builders will prefer to mould their own blocks, especially for the purpose of controlling the quality of the blocks, and to reduce the cost of transportation.

Let us assume that you have decided to mould your own blocks, and you have been faced with the challenge of estimating the quantity of and sand to purchase that will satisfy the construction requirement. This article will give you a guide on how to estimate the quantity of sand and required for moulding blocks in Nigeria.

- Initial data Number of blocks required = 3000 pieces
- Recommended production = 1 bag of cement to produce 35 blocks
- Step 1: Calculate the volume of the block

For the block size shown above;Volume of block without holes = (0.45 × 0.225 × 0.225) = 0.02278125 m 3 Volume of holes = 2(0.225 × 0.125 × 0.15) = 0.0084375 m 3 Therefore volume of the block = 0.02278 – 0.0084375 = 0.0143 m 3 Step 2: Calculate the volume of the 35 blocks If the volume of 1 block is 0.0143, the volume of 35 blocks = (0.0143 × 35) = 0.502 m 3 Step 3: Calculate the volume sand required for the 35 blocks The volume of 1 bag of cement is 34.72 litres = 0.03472m 3,This is obtained by knowing that the mass of 1 bag of cement = 50kg, and the density = 1440 kg/m 3 The volume of a standard builder’s wheelbarrow is 0.065 m 3 (unheaped). Builder’s wheelbarrow

- Total volume of 35 blocks required = 0.502 m 3
- Let the number of wheel barrow trips of sand be x

Hence, (volume of 1 bag of cement) + (Total volume of sand) = Volume of 35 blocksHence, 0.03472 + x (0.065) = 0.502 m 3 On solving, x = 7.1889 unheaped wheelbarrow trips of sandThe volume of sand required to make 35 blocks = 7.1889 × 0.065 = 0.46728 m 3 However, note that this leads to a mix ratio of about 1:14 which will not be very good when subjected to a compressive strength test.

- Step 4: Calculate the total volume of materials required We can therefore estimate the quantity of materials to be purchased;
- If 1 bag of cement is needed for 35 blocks, therefore 86 bags of cement is needed to mould 3000 blocks (gotten by 3000/35)

If 0.46728 m 3 of sand is required to make 35 blocks, therefore, 41 m 3 of sand (about 67.60 tonnes assuming the density of dry sand = 1600 kg/m 3 ) is needed to make 3000 blocks. For a 5 tonne tipper of 3.8 m 3 capacity, we have to order for 11 trips of sharp sand.

You have to be very sure of the size of the tipper that will be delivering the sand to you in order to make your estimates more reasonable. On the other hand, you can make the considerations for variations between the weight of materials when wet and when dry. However, this will never be critical for block moulding based on experience.

But in concrete it can be very considerable.

- Therefore summarily, we need 86 bags of cement and 68 tonnes of sand to mould about 3000 pieces of 9 inches blocks with holes (for 1 bag = 35 blocks).
