What is the quantity of cement required for 100 sq.m cement concrete (1:2:4) 4 cm thick floor?

Thickness =4cm=0.04m

Volume of wet concrete is1.54 to1.57

Ratio of mix1:2:4

Volume=1+2+4=7

unit weight of cement bag is1440 kg/cum one bag of cement =50/1440 =0.034722 cum

Quantity of cement = (1/7)=0.1429*1.54=0.22

                                        =0.22/0.0347

                                       =6.34bags

Weight of1 cement bag=50kg

                                         =6.34*50

                                        =317kg of cement is required

0.571cu.m of cement , approximately28 bags(50kg)

for one cubic meter concrete needs6-7 bags of cement (50kg)

40 bags.

21.11 bags

Approximately25 Bags of50 Kg cement with a dry cement volume of0.88 cu.m

cement required for100 sq.m =6bag
