Utilization of Granite Slurry Waste in Concrete: A Review

摘要

Objective: Huge quantity of granite production leads to the collection of enormous quantity of slurry. Random disposal of this generated waste degrades the environment in numerous ways. Utilization of this waste may solve the problem of waste generation and also the problem of scarcity of natural resources. Methods/Analysis: Granite slurry waste does not contain silt or organic impurities. Also, the use of this waste in place of cement will reduce energy demand, CO 2 emission and consumption of natural resources. Sufficient literature is available and it indicates that this waste can be used in place of Fine Aggregate (F.A.) or cement. In this paper salient available experimental studies using the granite slurry waste have been reviewed. Findings: It is shown that the granite slurry waste reduces the workability whereas compressive strength of granite concrete is improved when fine aggregate or cement is partially replaced. It has been also shown that the modified concrete performed well when level of F.A. by granite slurry waste is up to 15%. Conclusion/Application: Utilization of this waste will reduce the cost of concrete, reduce environmental pollution, consumption of natural resources and energy demand.
