Get QuoteThe size of coarse aggregates affects several aspects of the concrete, mainly strength and workability, and the amount of water needed for the concrete mix. It also helps determine how much fine aggregate is needed to produce a concrete batch. The bigger the size, the smaller is its bondable surface area for cement, sand and water; the less
Get Quote2. Grading of Coarse Aggregate. Grading is the determination of the particle-size distribution for aggregate. It affects the amount of cement and water requirements, workability, pumpability, and durability of concrete. The grading of coarse aggregate is important to get cohesive and dense concrete.
Get QuoteFine aggregate moisture content influences the mix proportion substantially. It specifies the amount of water that may be added to subtracted to the mixture. Mix design of concrete cannot be carried out without specific gravity of fine aggregate, and higher specific gravity produced stronger concrete.
