Abstract: The experimental shear strength of twenty (20) RC beams; 10 each of phyllite concrete and granite concrete without shear reinforcement were investigated. Five different beam cross-sections with similar shear span to depth ratios and two flexural tension reinforcement ratios (1% and 2%) were investigated. Higher amount of flexural tension reinforcement (2%) in each concrete type indicated an increase in the shear capacity and enhanced flexural strength. The RC beams made from phyllite aggregates exhibited lower ultimate shear capacities, lower diagonal cracking shear capacities, wider crack widths and lower ultimate displacement capacities as compared to the corresponding granite concrete beams. This is probably because the granite concrete showed effective bonding to longitudinal reinforcement resulting in adequate load transfer to increase beam strength and stiffness of granite beams. For the limited test results obtained from the study of the shear behaviour of phyllite concrete beams without shear reinforcement, ACI 18 was the most conservative whilst EC 2 appeared to be the most accurate
