Study of Mechanical Properties of Concrete using Recycled Aggregates

Abstract

Abstract: The last few decades have seen a rapid increase in urbanisation, which has increased demand for building materials, particularly aggregates. The aggregate mining has put a burden on the environment and raised concerns about swift ecological harm. Lack of building aggregates is a severe issue that requires the use of alternative recycled aggregates in its stead. Old, abandoned building debris is used to create recycled aggregates (RA), which are then hauled to a landfill and disposed of there. In addition to pushing waste sites farther away, the decades-long urbanisation of the region has also increased the expense of moving these aggregates. Utilising them in place of natural aggregates in concrete mixtures is the solution. Here in this study some proportion of natural coarse aggregate is being replaced by the recycled aggregate and analysis of its effect on various mechanical properties of concrete is being done. The mechanical properties of concrete constitute Compressive Strength, Flexural Strength, Shrinkage, Creep and Modulus of Elasticity.
