Abstract

AbstractConcrete is the most widely used construction material in the world. Over ten billion tons of concrete are being produced each year resulting in exhaustion of natural materials and an enormous carbon footprint. One of the primary goals of concrete technology today is to reduce the use of Portland cement and natural fine aggregates by partially replacing them with various waste materials and by-products of industrial processes. The paper summarizes the results of a study where the partial replacement of river sand and Portland cement was successfully applied using steel slag aggregate, silica fume and glass waste.

Summary

INTRODUCTION

When slag was used as an aggregate replacement in concrete it was concluded that the durability and the characteristics of steel slag cement concrete were better than those of normal concrete and it was highlighted that there is a reduction in slump and flow values as the slag content is increased in the mixture [3]. Junak et al [7] studied the usage of glass waste and steel slag in concrete mixtures They concluded that these materials could be used successfully instead of natural aggregates. Glass waste with a size range of 4–8 mm has a compressive strength of 35 MPa, which is close to normal concrete strength This product is recommended for preparing good quality concrete surfaces. In this work effect of glass waste and steel slag were checked by partially substitute fine aggregate, while silica fume was used as a partial replacement of ordinary Portland cement.
