  • Understanding the Role of Aggregates in Concrete Bay

    Understanding the Role of Aggregates in Concrete Bay

    Aggregates make up 60-80 of the volume of concrete and 70-85 of the mass of concrete. Aggregate is also very important for strength, thermal and elastic properties of concrete, dimensional stability and volume stability. Cement is more likely to be affected by shrinkage. Including aggregate in the mix can control the shrinkage level and ...

    Jul 18, 2021 Importance of aggregate crushing value test. This test indicates the strength of coarse aggregate, which most essential property of coarse aggregate. Coarse aggregate crushing value is the percentage by weight of the crushed material under standardised load and condition. The crushing value indicates the strength of aggregates.

  • The Effect of Aggregate Properties on Concrete

    The Effect of Aggregate Properties on Concrete

    Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm retained on a No. 4 sieve, while fine aggregate is less than 4.75 mm passing the No. 4 sieve. The compressive aggregate strength is an important factor in the selection of aggregate.
