How many cement bags in m25 concrete ? hi guys, in this post we know about how many cement bags used in m25 1 cubic metre of concrete and also know about how much cement, sand and aggregate required for m25 grade of 1m3 of concrrete.
we know that concrete is generally two types RCC and PCC in which RCC is reinforced cement concrete and PCC which is plain cement concrete.
in RCC concrete there is a used of reinforcement steel bar and PCC concrete is plain cement concrete without Steel.
concrete is mixture of cement sand and aggregate in fixed proportion and m25 is standard grade of concrete that is used in only RCC and not used in PCC work
what is the cement mortar ratio of m25 concrete : There are different types of grade of concrete like M5, M 7.5 ,M10, M15, M20, M 25 and so on. But in this topic we have to study about m25 grade of concrete. M Stand for mix and numerical figure 25 is compressive strength of curing time of 28 days.
And cement mortar mix ratio in m25 grade of concrete is (1:1:2) in which one part is cement 1 part is sand and 2 part is aggregate.
How many cement bags in m25 concrete
Given volume of concrete = 1m3
Wet volume of concrete = 1m3
For converting wet volume to dry volume to we will multiply 1.54 in wet volume of concrete
Dry volume = wet volume×1.54
For calculation of dry volume we multiply 1.54 into wet volume
Dry volume = 1m3×1.54 = 1.54 m3
Density of cement = 1440 kg/m3
Mix ratio of mortar = 1 : 1 :2
Total proportion = 1+1+2=4
Part of cement = 1/4
Part of sand = 1/4
Part of aggregate = 2/4
no of cement bags in m25 concrete
Weight = volume× density
Weight of cement = 1/4×1.54 m3×1440 kg/m3
Weight of cement = 554.4 kg
1 bags cement = 50 kg
bags of cement = 554.4/50 =11.088
no of cement bags in m25 = 11.088
11.088 bags cement are used in m25 grade of 1m3 concrete

How much cement sand and aggregate required for m25 concrete
1) quantity of cement in m25 concrete
11.088 no (554.4 kg) of cement bags are used in m25 grade of 1m3 concrete
2) volume of sand in cft for m25 concrete
1m3 = 35.32 cft
Volume =( 1/4) × 1.54×35.32
Sand volume = 13.6 cft
13.6 Cu ft of sand quantity are used in m25 grade of 1 cubic metre of concrete
3) volume of aggregates in cft for m25 concrete
1m3 = 35.32 cft
Volume =( 2/4) × 1.54×35.32
Aggregates volume = 27.2 cft
So quantity of material in m25 grade of 1 cubic metre concrete is following
bags of cement in m25 = 11.088
Volume of sand = 13.6 cft
Volume of aggregates = 27.2 cft
11.088 bags cement, 13.6 cu ft sand & 27.2 cu ft aggregate are quantity of material required for m25 grade of 1 cubic metre of concrete
