This paper verified the relation between flexural strength and aggregate/cement ratio for concretes made of granite chippings. The crushed granite chippings were from Abakaliki in Ebonyi State, Nigeria. By varying the aggregate/cement ratios, concrete beams of dimensions 600mm x 150mm x 150mm were made at water/cement ratios of 0.55 and 0.575 by weight respectively. These beams were then tested for their flexural strengths. The graphs of flexural strengths versus aggregate/cement ratios showed that the flexural strength decreased parabolically with increase in the aggregate/cement ratio. The regression equations of the graphs were polynomials of the second order. A z-test was used to prove the validity of these equations.
