The effect of kenaf core and quarry dust as sand replacement in sand cement bricks / Mohd Za'im Mohd Nor

Construction sector is focusing in developing sustainable, green and eco-friendly building materials as well as requirement for producing lightweight product. High demand and dependency of sand for construction industry caused a shortage of resources in future. Alternative resources are needed as replacement of sand. This research studies the effect of kenaf core and quarry dust as sand replacement in sand cement brick. The investigations cover heat of hydration, compressive strength, density, water absorption and porosity of Kenaf Core Quarry Dust Bricks (KCQB). Properties of normal sand cement brick was used as control parameters to see the effect of kenaf core and quarry dust. A series of mix designs was prepared and noted as cement paste without aggregate (MO), normal sand brick (Ml), contain 100% quarry dust (M2) and contain 100 % kenaf core (M3) and ten (10) types of mixes containing different percentage of kenaf core and quarry dust noted as M4, M5, M6, M7, M8, M9, M10, M11, M12 and M13.
