Assuming:-

Volume of brickwork = 1m³

Size of brick—>19x9x9 cm

Thickness of mortar = 10mm (1cm)

### Quantity of Bricks:-

** No. of bricks = Volume of brickwork/ volume of 1 brick with mortar**

Volume of 1 Brick with mortar = 0.20×0.10×0.10=0.002 m³

∴ No. of bricks = 1/0.002 = **500 ****No’s**

**Quantity of cement:-**

Volume of bricks= (0.19×0.09×0.09) x 500 = 0.001539 x 500 = 0.7695 m³

**Quantity of mortar = Quantity of brickwork – Volume of bricks**

Quantity of mortar = 1 – 0.7695 = 0.2305 m³

**Mix Ratio –> 1:6**

**Dry volume of mortar = Wet volume x 1.33**

Dry Volume = 0.2305 m³x 1.33 = 0.3066 m³

**Quantity of Cement = {(Dry Volume of mortar x Cement ratio) / (Sum of the ratio)}**

∴Quantity of cement = (0.3066 x 1) /(1+6)=0.0438 m³

**Density of Cement = 1440 kg/m****³**

∴ Weight of Cement = 1440 x 0.0438 = 63.072Kg

**1 bag of cement contains 50 kg of cement **

∴ Number of bags = 63.072 Kg / 50 kg = **1.261 No’s**

** Quantity of Sand:-**

** Cement : Sand :: 1:6**

**Quantity of Sand = Quantity of Cement x 6**

∴ Quantity of Sand = 0.0438m³x6= **0.2628 ****m³**

**1 m³=35.3147 Cubic Feet (CFT)**

∴ Quantity of sand = 0.2628 x 35.3147 = 9.280 CFT

**Density ****of sand = 1920 kg/m³**

∴ Weight of the sand= 0.2628 x 1920= 504.576 kg =>0.504 tonnes

**Material Cost:-**

**Labour ****Cost:-**

**Area=volume/thickness**** = 1m³/0.20m = 5m²**

**Summary:-**

Cost of material = Rs. 3271.13

Cost of labours = Rs. 3237.5

Sum of labour & material cost= **Rs****. 6508.63 **

Add:-

1.Water charge **@ 1.5% **= (1.5/100)x6508.63 = **Rs****. 97.629**

2.Contractor’s profit **@15 % **= (15/100)x6508.63= **Rs****. 976.294**

**Total cost = 97.532 + 975.323+6502.15 = ****Rs****. 7582.553**

So, Cost of brickwork may vary from** Rs. 6000 to 8500** based on location

I would like to know that when the average thickness of BBC is 115mm, with the average thickness of plaster in the ratio of (1:4) of 20mm top and bottom plaster of average thickness, mixed with IS 2645 as per the dose recommended by the manifacturer, then the average thickness of BBC is 75mm in the ratio of(1:4;8) mixed with IS 2645. The plaster thickness of 20mm can be calculated from the density of the motar, which is 2200Kg/Cum.
