For making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test. The compressive stress result is known as "grade of concrete'. It is expressed in N/mm²
Sep 10, 2018· M7.5 GRADE. Mix ratio is 1:4:8 (1 Cement, 4 Sand and 8 Aggregate) Application/use:- To provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete from the soil. ORDINARY GRADE OF CONCRETE. M10 GRADE. Mix ratio is 1:3:6 (1 Cement, 3 Sand and 6 Aggregate) It is used as PCC (Plain Cement Concrete)
"M" stands for "mix". Mix represents concrete with designated proportions of cement, sand and aggregate. And the number following "M" represents compressive strength of that concrete mix in N/mm 2 after 28 days. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2.

Weight of Coarse Aggregates = volume x density, Density of Coarse Aggregates = 1520 kg/m^3 Weight of Coarse Aggregates = 0.84 x 1520 = 1276.8 kg (1.28 tonnes) The above calculation you can use for all Grade of Concrete but just you have to put the different Grade of concrete like M10, M 15, M20, M25 etc. just here with grade of concrete you can ...
Calculate cement concrete mix design or Estimate how much cement concrete volume is required for your construction using our free online calculator. Know exactly how many bags, kg and ton of cement, sand and aggregate is needed of specific cement, sand and aggregate ratio(m20, m15, m10, m7.5)
Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
May 17, 2017· To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-
Aug 03, 2018· Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg

Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water. It has many applications, from fence posts to motorway bases and, because of this, there are many different concrete mix ratios that the constituents can be mixed to with each resulting in a different strength of concrete.

There are two methods: one is to use a variety of materials amount per 1 cubic meters, such as cement 300 kg, water 180 kg, sand 690 kg, gravel 1260 kg; the other is that the water cement ratio and cement ratio and concrete content of ...
Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened.The strength concrete is inversely proportional to the water/cement ratio.
