Cement, Sand, Coarse aggregate, and water with a suitable proportion of water.. All of these components are mixed according to batching or Concrete grade table, Maybe M10, M20, M25, M30, etc. Mostly M25 and M30 always used in construction industries for multistory buildings.
Jul 29, 2019 21AA CRUSHED CONCRETE. 21AA Crushed Concrete is great for drainage which makes it the right solution in wet areas. Its often used as a surface for driveways or parking lots. 21AA Natural. 21AA Natural is a looser material that works for gravel roads or as a base layer underneath asphalt pavement. 22A Crushed Concrete.
The basic ingredients of concrete are Portland cement, sand and water. Portland cement is the type used most often in the mixing of concrete. Its not a brand of cement but a generic term, much as stainless is a type of steel. Because concrete is soft when mixed, it can be formed into any shapea bridge, outdoor benches, a sidewalk.
For example, for M30 grade, the mix proportion can be 112, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. The strength measure with concrete cube or cylinders by civil engineers at the construction site.
2.4 Mix Design for M25-Grade Concrete The above mix designs are used for casting concrete specimens. The water-cement ratio changes for different dosages of super plasticiser. Usage of super plasticiser reduces the water requirement and new wc ratios are obtained.

Jun 10, 2014 The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand. Crushed sand particle though shaped, does not have the spherical shape of natural sand.
