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
