Properties of Sustainable Concrete Containing Limestone: A Review

The most frequently used building material on this planet is concrete. Concrete is the supreme user of natural resources as a result of its widespread use as construction material. Cement production produces significant amount of greenhouse emissions. The protection of environment has become challenging in many developing countries, 7-8% of CO2 is produced by the cement industry that causes huge damage to the environment. In concrete production, and limestone can be a partial alternative to cement. The limestone waste is transported and disposed in landfills. The disposal of limestone waste material in the open areas is causing several problems. In this study, the properties of concrete incorporating limestone waste are reviewed. Workability, compressive strength, split tensile strength, flexural strength, modulus of elasticity, and durability are among qualities of limestone waste concrete that have been discussed in this study. The cement was replaced by limestone waste in the ratio of 25% to 30% in concrete By limiting the waste of limestone in the concrete, cement content can be reduced, which turns into an eco-friendly solution.
