How many cement bags in m20 concrete ? Hi guys in this article we know about how many cement bags per cubic metre of M20 grade of concrete & what is the ratio of m20 concrete & how much quantity of cement sand and aggregate are required for 1m3 of m20 grade of concrete & also know about m20 concrete cement bags.

we know that concrete is generally two types **RCC that is reinforced cement concrete and PCC** which is plain cement concrete. in RCC concrete there is a used of Steel and PCC concrete is plain concrete without Steel.

concrete is mixture of cement sand and aggregate in fixed proportion and **m20 is standard grade of concrete that is used in both RCC & PCC work**

**what is the cement mortar ratio of m20 concrete,t**here are different types of grade of concrete like** M 7.5 ,M10, M15, M20, M 25** and so on. But in this topic we have to study about m20 grade of concrete.**M Stand for mix and numerical figure 20 is compressive strength of curing time of 28 days. And mix ratio in m20 grade of concrete is (1:1.5:3)** in which one part is cement 1.5 part is sand and 3 part is aggregate.

**How many cement bags in m20 concrete **

For calculating how much cement required for M20 concrete we need

Given volume of concrete = 1m3

Wet volume of concrete = 1m3

If we convert wet volume to dry volume of concrete then we will multiply 1.54 in wet volume of concrete.

Dry volume of concrete = wet volume ×1.54

Dry volume of concrete = 1m3×1.54 =1.54 m3

Density of cement = 1440 kg/m3

Mix ratio for m20 concrete is 1 : 1.5 :3, in which one part is cement, 1.5 part is sand and 3 part is aggregate

Total proportion = 1+1.5+3 = 5.5

Part of cement = 1/5.5

Part of sand = 1.5/5.5

Part of aggregate = 3/5.5

** no of cement bags in m20 concrete**

Weight = volume× density

Weight of cement = 1/5.5×1.54 m3×1440 kg/m3

Weight of cement = 403.2 kg

1 bag cement weight = 50 kgh

**How many cement bags in M20 concrete?** 1m3 of M20 concrete require 403kgs of cement, 1 cement bags weight = 50kgs, no of cement bags in m20 concrete = 403.2/50 = 8.064 bags, so around 8 bags cement required in M20 concrete.

**how much cement required for M20 concrete?** their answer is 8 bags (403 kgs) cement required for m20 concrete.

**How much cement sand and aggregate required for 1m3 of m20 concrete**

1) 8.064 no ( 403.2 Kg) of bags of cement required for 1m3 of M20 concrete

**2) volume of sand in cft for 1m3 of m20 concrete**

1m3 = 35.32 cft

Dry volume of concrete = 1.54 m3

Part of sand in mix ratio = 1.5/5.5

Volume =( 1.5/5.5) × 1.54×35.32

Sand volume = 14.83 cft

● Ans. :- 14.83 Cu ft sand quantity required for 1m3 of m20 concrete

**3) volume of aggregates in cft for 1m3 of m20 concrete**

1m3 = 35.32 cft

Volume =( 3/5.5) × 1.54×35.32

Aggregates volume = 29.67 cft

So quantity of material in m20 grade of 1 cubic metre concrete is following

bags of cement in m20 = 8.064

Volume of sand = 14.83 cft

Volume of aggregates = 29.67 cft

**M20 concrete cement bags:-** using dry volume is equal to 1.54 times of wet volume of concrete, about 8bags (400kgs) of cement required for 1 cubic metre of M20 concrete grade in ratio 1: 1.5: 3, in which one part is cement, 1.5 part is sand and 3 part is aggregate with compressive strength of 28N/mm2 within 28 days after casting & curing.

● Ans. :- 8.064 bags cement, 14.83 Cu ft sand & 29.67 Cu ft aggregates are quantity of material required for M20 grade of 1m3 concrete.
