How Many Cement Bags For Slab
How many cement bags are required for a 100m2 slab? – ◆ Given dimensions :- roof slab thickness ranging between 4 inch (100mm) to 6 inch (150mm) but in this calculation we take roof slab thickness is 5 inch (125mm) Roof slab thickness =125mm = 0.125m Area of slab = 100m2 Mix ratio = 1:1.5:3 ◆ Volume Calculation :- 1) wet volume =Area × thicknessof slab Wet volume = 100m2 × 0.125m = 12.5 m3 2) Dry volume :- we know that wet volume have voids and pore which filled with water and bubbles it can be remove by vibrator or compressor machine so more quantity of material is required.

dry volume means mixture of cement sand and aggregates concrete in dry condition have more voids and pores that are evaporated in wet condition and volume is decrease by 54 percent in wet condition and volume of dry concrete in increased by 54%, so we can multiply 1.54 in wet volume to calculate dry volume Dry volume = 12.5m3 × 1.54 = 19.25m3 ◆ Cement bags for 100m2 rcc slab Mix ratio = 1:1.5:3 ( 1 part cement,1.5 part sand and 3 part is aggregate) Total P = 1+1.5+3 = 5.5 Part of cement = 1/5.5 in M20 mix 1 part is cement quantity Weight of cement=1/5.5×dry volume in m3×density of cement Density of cement=1440kg/m3 Weight =1/5.5× 1925 m3×1440 kg/m3 Weight of cement = 5040 Kg 1 bag cement = 50kg No.
