Are you looking for premium quality coarse aggregates in Chennai? We are the leading supplier of the best building materials in and around Chennai. Our wide range of construction aggregates (6mm, 12mm, 20mm, 40mm, 60mm) is also available online.
The selection of the right aggregate size depends upon the usage/application of the concrete. To help you make an informed choice, we have a short guide on coarse aggregates and our offerings.
Coarse Aggregates
Aggregates are torpid granular materials that provide volume to the concrete. The ones that cannot pass through the IS Sieve of 4.75mm are called coarse aggregates. Coarse aggregates are usually formed by blasting the stone pits. Hard crushed rocks (granite and limestone) and natural river gravels are the most prevalent aggregates used in structural concrete.
Characteristics of good quality Coarse aggregates
- Coarse aggregates should be hard. They should have good load-bearing strength.
- Coarse aggregates should be chemically inert, i.e., not react with mixing agents like cement, bitumen.
- They should be free from organic or inorganic impurities because impurities can adversely affect the bonding strength of concrete.
- Coarse aggregates should not absorb more than 5% water. The higher water absorption can cause problems with the workability and durability of the concrete.
- Good quality coarse aggregates are usually angular or cubical.
Classification of coarse aggregates based on origin
Coarse aggregates are either natural or artificial, depending upon their source of origin.
1. Natural Aggregates
Natural aggregates exist in the form of gravel or crushed aggregates.
2. Gravel
Most of the gravel is procured from the river beds or streams. It is formed by weathering of bedrock and deposition by water or gravity.
3. Crushed Aggregates
Crushed aggregates are tiny rock fragments obtained by the blasting of the stone quarries. They go through the mechanized crushing, washing, and sizing processes to obtain the desired sizes.
4. Artificial Aggregates
Artificial aggregates are industrial by-products. Their usage helps to curb environmental pollution and the depletion of natural resources. Ash, rice husk, granite powder, furnace slag, power station solid waste, iron-ore slag, etc., are common artificial aggregates.
