Assessment of the Effect of Replacing Normal Aggregate by Porcelinite on the Behaviour of Layered Steel Fibrous Self-Compacting Reinforced Concrete Slabs under Uniform Load

Table 8

Effect of steel fiber volume fraction (V_f) on splitting tensile strength, compressive strength, and density of normal-weight and lightweight concretes.
