What Is Coarse Aggregate | Requirements of Good Coarse ...
Coarse Aggregates in concrete provides body and strength to the concrete and acts as a filler material which will give the homogeneous mass of the concrete.. Coarse aggregates are used in every Construction projects which includes the construction of roads, Buildings, Railway Tracks etc.. Coarse Aggregate in concrete was considered as chemically inactive and acts as a filler material only.Get Price
Energy Absorption Characteristics of PVC Coarse Aggregate ...
· Waste plastics have brought about serious pollution around the world. Replacing aggregate in concrete with plastics such as PET and PVC is a simple and environmentally friendly waste plastics recycling method (Opon Henry, 2019).Although mixing more plastics can obviously decrease the strength of plastic concrete and increase the water absorption rate (Hu Xu, 2020a, 2020b), it .Get Price

Aggregates | Difference Between Coarse And Fine | How to ...
Aggregates: Aggregates are inert granular, substances like either sand gravel or crushed stone which are an important component in concrete, alongside water and portland cement.. Aggregates must be pure, hard, solid particles free from ingested chemicals or adhesives of clay as well as other fine materials for a good concrete mix that could trigger the concrete to deteriorate.Get Price
