# 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.

of bags of cement = 5040/50 Number of cement bags are required for 100m2 slab = 100.8 bags.100.8 cement bags are required for a 100m2 slab. ◆You Can Follow me on Facebook and Subscribe our Youtube Channel You should also visits:- 1)what is concrete and its types and properties 2) concrete quantity calculation for staircase and its formula ◆Now your turn: – please like and comment it above this post, if you have any query and question about this please you will ask, thanks a”lot.

## Can you pour a slab with bagged concrete?

Successfully pouring a concrete patio or driveway requires detailed site prep, planning, and careful finishing. – istockphoto.com Learning to pour concrete may save money and build your skills, but without proper equipment and attention to detail, the results can look far from professional.

2. Gravel provides a solid foundation for your concrete as it can be compacted.
3. It also improves drainage, preventing water from pooling beneath the concrete.
4. While some may argue that very solid soils such as clay provide just as good a base as gravel, they still do not provide adequate drainage.
