Utilization of natural and industrial mineral admixtures as cement substitutes for concrete production in Jordan

Several materials such as tuff and Tripoli which is naturally occurring and industrial by-products wastes as high calcium ash and slag were investigated as cement substitutes in this paper. Compressive strength of various standard mortar samples have been tested at 7 and 28 days. The obtained results show that these materials have improved the properties Ordinary Portland Cement (OPC) concrete. It was found that an...

Code compliant behaviour of palm kernel shell reinforced concrete (RC) beams in shear

This paper evaluates the shear strength of simply supported palm kernel shell (PKS) concrete and normal weight concrete (NWC) beams subjected to four-point loading. The primary variable of the investigation was evaluation of shear capacity of reinforced PKS concrete and NWC beams with and without shear reinforcement. Four pairs of reinforced concrete (RC) beams with similar geometrical properties were designed and...
