Utilization of Recycled Glass as Fractional Replacement of Cement and Waste Concrete as an Aggregate in Sustainable Concrete Practice

Abstract

This paper summarizes the ongoing  researches about the effect of recycled glass powder and the  recycled aggregates on conventional concrete Practice. Many  studies on using the recycled powdered glass and the  recycled aggregates in conventional concrete practice that  have been carried out earlier were studied, and their effects  on the conventional concrete were also analyzed. In this  paper we will analyze the individual effects by these each  replacements and then I will combine both the materials in  concrete and will analyze the result of that concrete. Glass  mainly consists of silica. Utilising the powdered glass waste  as fractional replacement could be proven an efficient step  for the development of sustainable infrastructure systems.  When the recycled waste glass is grinded into the powdered  form with micro size particles, it exhibits pozzolanic  reactions with the hydrates of cement, resulting in the  formation of secondary C-S-H products. Similarly the use of  recycled concrete as aggregate would also result into the  development of sustainable infrastructure systems. Similarly  possibility of utilization of recycled concrete as aggregate  has been concluded to have positive impact on the fresh  concrete production.
