Comparison of Dimension Limestone Waste Coarse Aggregates with Traditional Coarse Aggregates

Abstract

Concrete production is extensive nowadays for various engineering applications, and it has been estimated that approximately 26.8 billion tons of concrete are produced annually. To overcome the deterioration of natural resources and sustainable environment once need to find an alternative sources to produce sustainable concrete. The present work emphasizes on curtailing the disposal-related pollution from mining of dimension limestone waste which can act as replacement of coarse aggregates in concrete mixes. Concrete mixes with different types of coarse aggregates like dimension limestone waste, sandstone, basalt, and quartz are prepared at three different water cement ratio that are 0.35, 0.45, and 0.55. The properties like compressive strength, chloride penetration, water permeability, and abrasion resistance are evaluated for all concrete mixes. The experimental results indicate that dimension limestone waste shows higher strength and higher abrasion resistance than the sandstone aggregates at 0.45 and 0.55 w/c suggesting that its utility can be used for high as well as low strength concretes. Also, the dimension limestone waste coarse aggregates shows more durability than sandstone aggregates when water permeability properties and chloride penetration test results were compared.
