Weight = Volume x Density=(3.14/4)x D x D X 1x7850 (if D is in mm ) So = ((3.14/4)x D x D X 1x7850)/(1000x1000) = Dodd/162.27 DESIGN MIX: M10 ( 1 : 3.92 : 5.62) Cement : 210 Kg/ M 3 20 mm Jelly : 708 Kg/ M 3 12.5 mm Jelly : 472 Kg/ M 3 River sand : 823 Kg/ M 3 Total water : 185 Kg/ M 3 Fresh concrete density: 2398.
1x7850 (if D is in mm ) So = ((3.14/4)x D x D X 1x7850)/(1000x1000) = Dodd/162.27. DESIGN MIX: M10 ( 1 : 3.92 : 5.62) Cement : 210 Kg/ M 3 20 mm Jelly : 708 Kg/ M 3 12.5 mm Jelly : 472 Kg/ M 3. River sand : 823 Kg/ M 3. Total water : 185 Kg/ M 3. Fresh concrete density: 2398 Kg/M 3. M20 ( 1 : 2.48 : 3.55) Cement : 320.
So, we can't use M10 for structural components like footings, beams, etc. But when we have to lay footings on the ground, then we need a flat and solid surface for a uniform flow of load from footing to ground. In this case we use M10 or M15 grade of concrete in the for Dry Lean Concrere or DLC. Another use of M10.

Concrete is classified into different grades like M5, M7.5, M10, M15 etc., where M stands for Mix and the following number stands for characteristic compressive strength(fck) of concrete in 28 days in the Direct Compression test.For example, If the ratio of M20 concrete is 1:1.5:3, then 1 part of cement, 1.5 parts of sand and 3.
This construction video tutorial is created on Concrete Mixes. Various topics like categories of mixes, purpose for using mixes. Fundamental types of the concrete mix range from nominal mix, standard mix and design mix. There are different types of grades for concrete mixes like M5, M7.5, M10, M15, M20, M25, M30, M35,.
Types of Mixes. 1. Nominal Mixes. Advertisements. In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed . IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the.
The above calculation you can use for all Grade of Concrete but just you have to put the different Grade of concrete like M10 , M15 , M20 , M25 etc. just here with grade of concrete you can change the proportion and the method is just above which I have discuss .
All the raw materials of concrete such as cement, sand and stone chips are collected in the required proportion and then put into the rotating drum and is rotated firstly in dry state and then water is added in the amount sufficient to make a workable concrete. These machines are of both the types i.e. tilting and non-tilting.
