journal about grading aggregate ideal for concrete

As aggregate covers 75 percent of the volume of concrete, for HSC, high-strength well-graded aggregate is essential. The presence of different sizes of aggregate (well-graded) in appropriate proportions is important to reduce void.

Concrete Mix Design Calculations

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.

Concrete Mix Ratio by Volume. 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.

The density of concrete is a measurement of concrete's solidity. The process of mixing concrete can be modified to form a higher or lower density of concrete end product. A very high density of concrete is that made around steel cables that have been stretched by hydraulic jacks. The concrete is allowed to harden and then the jacks are released.
