How Do I Calculate Brick, Sand And Cement In Brick Masonry?

**Before Going To Know About Calculation Of Brickwork**

**LCETED**trivia about brickwork

*To know more information about brickwork click here.*

*Assume the given data is*

**1. Class A brick (228mm × 107mm × 69m)**

2. Size of the wall for brickwork = 3m x 3m (4") wall

3. Grade of mortar = 1:6 (cement : sand)

**STEP 1: CALCULATION OF BRICKS**

**No. of bricks = (volume of brickwork/volume of one brick with mortar)**

**Volume of one brick without mortar**= 228x107x69= (mm->m) = (0.228x0.107x0.069) =

**0.00168m**

^{3}

^{}**Since Thickness Of Mortar = 10 mm (0.01 m)**

**228x107x69mm = 238x117x79mm**

**Volume of brick with mortar**

*=*(0.228+0.01) x (0.107+0.1) x (0.069+0.1) = 0.238x0.117x0.079 =

**0.002199834**

**m**

^{3}

^{}**Therefore,**

^{3}= 1.0 / (0.002199834)

**=**

*454.57*^{3}

**Consider The Percentage Of Waste**

*As 10 % Or 15 %*

**Total no. of bricks**= 440 + (10 x 440 )/100=

*484 - 500 nos*

**STEP 2: CALCULATION FOR QUANTITY OF MORTAR**

**Since we need 500 no of bricks for 1m**

^{3}^{3}

^{}

**Volume Of Mortar = Volume Of Brick Work for 1m**

^{3 }- Volume Of Bricks**Therefore,**

^{3}

^{}

**STEP 3: CALCULATION OF QUANTITY OF CEMENT**

**Cement = (Dry Volume Of Mortar X Cement Ratio)/ Sum Of The Ratios (Proportion)**

^{3}

^{}

**33% Increment Due To Volume Shrink After Water**

**:**

*While working with first-class bricks, it should be noted that for the walls with the thickness of*

**9”**the cement-sand ratio for brick masonry should be**1:6**and when it comes to a wall of**4.5”**thickness the ratio can be made**1:4.**^{3}

^{}

*LCETED TRIVIA FOR CIVIL ENGINEERS*

*We believe the standard density of 1 cement bag is equal to 1440 kg/m3***bags**

**Therefore,**

^{3}brick masonry needs 500 bricks and 0.87552 bags

**So,**

**1**

**Bags**

**STEP 4: CALCULATION FOR QUANTITY OF SAND**

**Sand =**

**(Dry Volume Of Mortar X Sand Ratio)/ Sum Of The Ratios(Proportion)**

**OR**

**Sand = Cement Volume X 6 ( Since 1:6 Grade Of Mortar)**

**Therefore,**

*LCETED TRIVIA FOR CIVIL ENGINEERS*

*We believe the standard density of 1 m*^{3}sand is equal to 1600 kg/m3**OR**

*6.420*

*cft (generally there are 22 cubic feet of sand in a ton)*

*0.963m*

^{3}of brick wall need sand in cft = 0.963 x 6.420 = 6.182 - 7

**cft**

**So, The Result For Given data**

^{3}

^{ }

*NUMBER OF BRICKS = 500 nos*

*CEMENT = 1 BAGS OF 50 KG*

*SAND = 7 cft***ALSO USE: Brick Masonry Calculator | Brick wall Material Calculator | Brick Quantity Calculator **

**How much cement, sand, and bricks are needed for 1 cubic metre of brickwork? **

For one cubic meter (cum)
brick wall we need **455 nos bricks**, **43.776 kg cement** and ** 6.420**** cft sand**

**How much cement, sand, and bricks are needed for 1 square metre of 9" brickwork?**

As we now, area of 1
square meter 9” thick brick wall (1 x 1 x 0.225 = 0.225cum) is 0.2225 so we
need **102.5 bricks, 9.8496kg cement and ****1.4445 ****cft sand**

**How much cement, sand, and bricks are needed for 1 square metre of 4.5" brickwork?**

As we know, the area of 1
square meter 4.5” thick brick wall (1 x 1 x 0.1125 = 0.115cum) is 0.2225 so we
need **51.25 bricks, 4.9248kg cement and ****0.72225****cft sand**
