### How many bags of cement in m25 grade of 1m3 of concrete

#### ■ what is the ratio of m25 concrete

■ introduction :-in this topic we know about how many bags of cement in m25 grade of 1m3 of concrete. 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 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 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 bags of cement in m25 grade of 1m3 of concrete

Given volume of concrete = 1m3

Wet volume = 1m3

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 = 1 : 1 :2

Total proportion = 1+1+2=4

Part of cement = 1/4

Part of sand = 1/4

Part of aggregate = 2/4

#### 1)■ bags of cement in m25

Weight = volume× density

Weight = 1/4×1.54 m3×1440 kg/m3

Weight = 554.4 kg

1 bags cement = 50 kg

bags of cement = 554.4/50 =11.088

bags of cement in m25 = 11.088

### 7) what is admixture of concrete and its types and its properties

2) volume of sand in cft

1m3 = 35.32 cft

Volume =( 1/4) × 1.54×35.32

Sand volume = 13.6 cft

3) volume of aggregates in cft

1m3 = 35.32 cft

Volume =( 2/4) × 1.54×35.32

Sand 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
