weight of 1 m3 of m25 concrete. Now question is how much cement required for 1m3 of M25 concrete their answer is followingAns 11 bags 0385 m3 554 kgs cement are The mix calculations per unit volume of concrete shall be as follows Volume of concrete 1 m3 Volume of cement Mass of cement Specific gravity of cement x 1100 39315 x 11000 0125 m3
For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

With only cement, the maximum cement content for any standard concrete not special concretes is generally be restricted to about 450 kgm3 Indian standard specification as per IS456-2000.
Concrete mix ratio of 133 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 watercement ratio.
Mar 27, 2017 Grades Of Concrete In IS 456-1978, the different grades of concrete are given as M10, M25, M20, M25, M30, M35, and M40. In the classification of concrete mix, the letter M denotes the Mix and the numbers 10, 15, 20, 25, 30, 35, 40 represent the predetermined works cube strength of 15 cm cubes after curing of 28 days in Nmm2.
Thus, large concrete construction projects uses design mix concrete. So, suitable grade of concrete can be selected based on structural requirements. Nominal mixes for grades of concrete such as M15, M20, M25 are generally used for small scale construction.
This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent ...
The basic requirements for the design of concrete mix ratio are 1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10 ...

Water Content and Concrete Mix Ratio . The more water that is added to a concrete mix, the more fluid and workable the concrete becomes. However, this comes with a price of strength. More water equals weaker concrete. The water-cement ratio is important for the concrete to reach its design strength.
