concrete mix design with coarse aggregate of 5to 20mm

  • Aggregates for Concrete

    • For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. • Aggregates are divided into either 'coarse' or 'fine' categories. - Coarse aggregates are particulates that are greater than 4.75mm .

    Jan 15, 2017 · Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
