Full Length Research Paper
This study investigates workability and the compressive strength properties of self-compacting concrete with palm kernel shell ash (PKSA) as mineral additive for partial cement replacement. The iterative method mix design was used, where water and super plasticizer contents were fixed while solid constituents were adjusted for optimum performance. The mixes were to achieve EFNARC’s 650 and 800 mm slump-flow limits. The results showed that up to 25% replacement of cement using PKSA produced self-compacting concrete with the workability criteria met and comparable compressive strength.
Key words: Self-compacting concrete, palm kernel shell ash (PKSA), additives, strengths.
