Assessment of Malaysian Laterite Aggregate in Concrete

Integration of new material as a partial coarse aggregate replacement in local concrete production would be able to reduce the high dependency of concrete manufacturer on granite aggregate supply that may lead to ecological imbalance when this natural material is used excessively. This paper present...
