Investigation into the properties of self-compacting concrete with palm kernel shell ash as mineral additive


This study investigates workability and the compressive strength properties of self- compacting concrete incorporating palm kernel shell ash (PKSA) as mineral additive for partial cement replacement.. The mix design was based on the iterative method where solid constituents were adjusted while water and super plasticizer contents were fixed to produce optimum viscosity and flowability. All mixes were designed to achieve EFNARC slump-flow with conformity criteria _ 650 mm and _ 800 mm. Test results show that up to 25% replacement of cement using PKSA produced self - compacting concrete where the workability criteria of filling ability, passing ability and segregation resistance were met and comparable compressive strength to normal high strength self - compacting concrete were achieved.
