How Much Sand And Cement For 100 Bricks?

In brick work you need 487 bricks, 0.25 cum of mortar 1:4 using 20 kg of cement and 40 cft of sand. For your 100 bricks 1/5 of above shall be the requirement. ( Bricks 100 cement 5 kg sand 1 bag.)

How much sand and cement do I need for 100 blocks?

Averages – As a general rule, you can order around 600 to 800 pounds of sand for every 100 blocks you are setting, provided that you are using the standard size cinder block. You will use two and a half to three bags of cement mixed in with that sand.

1. However, the smaller the blocks, the more sand and cement you will need because there are consequently more joints to fill.
2. Whenever you are ordering for a project you should always order 15 to 20 percent extra.
3. This is doubly true with block projects because if you start trying to mix different batches of sand and cement, you can end up with a completely different color of mortar due to the inconsistencies of color in these natural products.

Always order more than what you think you need.

How much cement do I need for 200 bricks?

How many bags of mortar do i need for 1500 bricks? – Regarding this, “how many bags of mortar do i need for 1500 bricks?”, as a general thumb rule you will need approximately 52 bags of 80lb or 56 bags of 60lb premixed mortar for 1500 bricks.

How much cement is 100 blocks?

Ans. :- 1062 nos bricks and 2.68 bags ( 134 kg) of cement required for 100 sq ft brickwork of 9 inch brick wall.

How many blocks can 1 bag of cement make?

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

1. Total volume of 35 blocks required = 0.502 m 3
2. 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.

1. 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).
