Abstract

In limestone quarries, considerable amounts of limestone powders are being produced as byproducts of stone crushers. High amounts of powders are being collected and utilisation of this by-product is a big problem from the aspects of disposal, environmental pollution and health hazards. In conventional concrete, the introduction of high volumes of limestone quarry dust to concrete mixes is limited due to its negative effects on water demand and strength of concrete. However, these fines can be efficiently utilised as viscosity enhancer particularly in special concrete (like self-compacting concrete-SCC) applications. Thus, the successful utilisation of this quarry dust in SCC could turn this material into a valuable resource.
