TJust like cement, gravel is an important raw material from which concrete gets its strength. Gravel is also known as coarse aggregates and it is used for normal constructions ideally ranging from 10mm to 20mm, which are 10, 12, 16, 18 and 20mm.

When choosing gravel, you have to keep in mind its size and its shape. Don’t forget that the size of gravel differs based on its function. If you are using the gravel for columns, the size should range between 10 to 20mm.

However if the gravel is being used in the foundation, its size should range between 25 to 40 mm. You should always remember that the best quality gravel or coarse aggregates has to be angular in shape.

It is important to note when selecting coarse aggregates or gravel, ensure that the mix is similar in size and shape to avoid honeycombing and seepage. There are three important methods to help you select the best quality coarse aggregates.
Sieve analysis – This method covers the sampling and determination of the particle size distribution of coarse aggregates.
Length Gauge – This method is used to determine the elongation index of aggregates. Thickness Gauge – This method is used to determine if aggregate particles are to be considered flaky.
