Aggregate. Aggregate is the most exploited material in the world. It is an important component of concrete and asphalt concrete, accounting for 70% of the volume of concrete. It can inhibit the shrinkage and cracking of concrete and enhance the strength of concrete. Aggregates are divided into natural aggregates and artificial aggregates.

Like crushed stone, gravel can be used as an aggregate for pavement, ready mix concrete, or other construction applications. Best applications for crushed stone We have already referenced many places where crushed stone is used, but the most common are construction projects that need concrete, solid bases, or drainage systems.

M-20 = 1 : 1.5 : 3 = 5.5, (Cement : Sand : Aggregate) Some of Mix is – 5.5. Where, M = Mix. 20 = Characteristic Compressive strength. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation to find Cement, Sand and Aggregate quality in 1 cubic meter concrete.

While sand is the usual common aggregate managed to create concrete, you can also mix cement by gravel, crushed stone, or even parts of old concrete. … The quantity of water you mix in order depends on the aggregate substance, but you’ll want somewhere within 15 to 20 per cent of water.

Concrete may seem strong, but after many years, elements, and pressure, it will eventually crack. So in order to make your concrete last as long as your money that went into it, adding a layer of crushed stone under a slab of concrete will increase the life of your investment.
