Physical Properties of Aggregate: Flakiness Index The flakiness index of aggregate is the percentage by weight of particles in it whose least dimension (thickness) is less than three-fifths of their mean dimension. The test is not applicable to sizes smaller than 6.3 mm. The flakiness index is taken as the total weight of the

During hydration and hardening, concrete needs to develop certain physical and chemical properties, among others, mechanical strength, low permeability to ingress of moisture, and chemical and volume stability. The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used.
