Consulting products2012-3-16Aggregates gradation also have an influence on the compressive strength of concrete. Concrete strength increases when using dense gradation and increasing fines modulus of aggregates. By increasing fines modulus surface area of aggregates goes on increasing. With the increase in surface area more bond surface will be available and due to this stronger bond will be formed and also this
