**How many bags of cement for 1000 bricks**

**■ sand and cement for 1000 bricks**

**■ description** :- in this topic we will learn about how many bags of cement for 1000 bricks, and also calculate quantity of sand and cement for 1000 bricks, we know that cement consumption is depend on many factors in brickwork like cement sand ratio mortar thickness and size of bricks . We know that we can have multiple shape and size it has nominal size that is called **modular bricks having dimenstion 190mm × 90 mm × 90 mm**

And second one is **Indian bricks having dimension approx 230 mm × 115 mm × 75 mm**. Cement consumption is more in higher size of bricks and cement consumption is less in lower size of bricks

**◆ factors determining cement consumption**

1) cement sand ratio

2) size of bricks

3) mortar thickness

**How many bags of cement for 1000 bricks for modullar bricks**

◆ **Given dimensions :-**

Thickness of mortar = 10 mm

Modullar brick size = 190mm×90mm ×90 mm

No of bricks = 1000

Cement sand ratio = 1:5

Total proportion = 1 + 5 = 6

Part of cement = 1/6

Part of sand = 5/6

**◆ how many bags cement for 1000 bricks**

◆ **Calculation :-**

Volume of 1 bricks =0.19×0.09×0.09 m3

Volume of bricks = 0.001539 m3

Volume of 1000 bricks = 1000×0.001539 m3

Volume of 1000 bricks = 1.539 m3

Mortar thickness = 10mm

Brick size with mortar = 200mm×100mm×100mm

Volume of brickwork for 1000 bricks

Brickwork volume = 1000× 0.2×0.1×0.1m3

Brickwork volume = 2 m3

**For mortar volume calculation subtract volume of brick from volume of brickwork for 1000 bricks**

Mortar volume = 2m3_ 1.539m3

Mortar volume = 0.461 m3

Mortar volume is known as wet volume

Wet volume = 0.461 m3

To calculate dry volume multiply a cofactor 1.33 in wet volume and 20% wastage of mortar

Dry volume = 0.461m3×1.33 = 0.613m3

20% wastage of mortar

20% of 0.613 m3 = 0.1226 m3

Total mortar volume = 0.613+0.1226 = 0.7356

How much cement needed for 1000 bricks

Density of bricks = 1440 kg/m3

Part of cement in ratio = 1/6

Volume of mortar = 0.7356 m3

Weight = volume × density

Cement quantity = (1/6)0.7356m3×1440kg/m3

Weight of cement = 177 kg

**So 177 kg of cement quantity is require for 1,000 brickwork**

**How many bags of cement for 1000 bricks**

1 bag cement = 50 kg

No of bags cement = weight of cement/50

No of bags cement = 177/50= 3.54 bags

**So 3.54 bags of cement is required for 1000 brickworks**

■ **sand quantity calculation**

Part of sand in ratio = 5/6

Volume of mortar = 0.7356m3

1 m3 = 35.32 cubic ft

Volume of sand in cubic metre

Volume = (5/6) 0.7356 m3 = 0.613 m3

Volume of sand in cubic feet

Volume = 0.613 × 35.32 =21.65 cft

**So quantity of sand is 0.613 m3 or 21.65 cft is required for 1000 brickwork**

**■ How many bags of cement for 1000 bricks for Indian Standard size of bricks**

◆ **Given dimensions :-**

Thickness of mortar = 10 mm

Modullar brick size = 230mm×115mm ×75 mm

No of bricks = 1000

Cement sand ratio = 1:5

Total proportion = 1 + 5 = 6

Part of cement = 1/6

Part of sand = 5/6

◆ **how many bags cement for 1000 bricks**

◆ Calculation :-

Volume of 1 bricks =0.23×0.115×0.075 m3

Volume of bricks =0.00198 m3

Volume of 1000 bricks = 1000×0.00198m3

Volume of 1000 bricks = 1.98 m3

Mortar thickness = 10mm

Brick size with mortar = 240mm×125mm×85mm

Volume of brickwork for 1000 bricks

Brickwork volume = 1000× 0.24×0.125×0.085m3

Brickwork volume = 2.55 m3

**For mortar volume calculation subtract volume of brick from volume of brickwork for 1000 bricks**

Mortar volume = 2m3_ 1.539m3

Mortar volume = 0.57 m3

Mortar volume is known as wet volume

Wet volume = 0.57 m3

To calculate dry volume multiply a cofactor 1.33 in wet volume and 20% wastage of mortar

Dry volume = 0.57m3×1.33 = 0.7581m3

20% wastage of mortar

20% of 0.7581 m3 = 0.15162 m3

Total mortar volume = 0.7581+0.15162

Total mortar volume = 0.81 m3

How much cement needed for 1000 bricks

Density of bricks = 1440 kg/m3

Part of cement in ratio = 1/6

Volume of mortar = 0.81 m3

Weight = volume × density

Cement quantity = (1/6)0.81m3×1440kg/m3

Weight of cement = 194 kg

**So 194 kg of cement quantity is require for 1,000 brickwork**

**How many bags of cement for 1000 bricks**

1 bag cement = 50 kg

No of bags cement = weight of cement/50

No of bags cement = 194/50= 3.89 bags

So 3.89 bags of cement is required for 1000 brickworks

**■ sand quantity calculation**

Part of sand in ratio = 5/6

Volume of mortar = 0.81m3

1 m3 = 35.32 cubic ft

Volume of sand in cubic metre

Volume = (5/6) 0.81 m3 = 0.675 m3

Volume of sand in cubic feet

Volume = 0.675 × 35.32 =23.8 cft

So quantity of sand is 0.675 m3 or 23.8 cft is required for 1000 brickwork
