Abstract

Abstract. To overcome the shortage of natural resources for the production of concrete, many waste materials are used to replace the raw materials of concrete. In this way, bottom ash is one of the major industrial wastes which shall be used as the replacement of materials in concrete production. It shall be used to replace the materials either up to one-third. This review brings out the evaluation of the industrial waste material which can be repeatedly used as a substitution for concrete as fine aggregate. This paper reviewed the use of industrial waste i.e., bottom ash as fine aggregate in the concrete. The parameters discussed were physical, chemical, fresh, and hardened properties of the concrete with partial replacement of bottom ash. By reviewing some of the research papers, concluded that 10-15% replacement of fine aggregates is acceptable for all the properties of concrete. High utilization of natural sources -gives the pathway to produce more industrial wastes which are responsible for the development of new sustainable development.

Highlights

The concrete production has a large amount of negative thoughts in the field of environment and globe .Concrete is one of the most used and widely manufactured material in the world
It has been observed the exact compressive strength, drying shrinkage, and wc ratio bottom ash is increased with decreases when it mixed with concrete
The analysis shows due to the low content of specific gravity in bottom ash the density of concrete is less

Summary

Introduction

The concrete production has a large amount of negative thoughts in the field of environment and globe .Concrete is one of the most used and widely manufactured material in the world. Concrete mainly derieved from fine aggregate, cement and sand [1] Out of these material cement is the major part of concrete which acts as a unaltered material in the field of construction .Concrete is produced by burning of natural materials like fly ash and slag of industrial by products ,limestone and clay [2].Concrete is one of the major production material in the world due to its cost effectiveness ,long term performance and easy application [3].Concrete is mainly used in the construction of parking garges ,offshore structures railway bridges in large numbers. To find the quality of bottom ash we have to concentrated on two mix design foremost one is W/c ratio and second important is stable slump value It has been observed the exact compressive strength, drying shrinkage, and wc ratio bottom ash is increased with decreases when it mixed with concrete. The drying shrinkage enlarge when the increased natural sand is replaced by bottom ash with 30%[5].The bottom ash concrete reveals good dimensional concrete, better water resistance to sulphuric acid and chloride particles with the comparision of traditional concrete[17].[18] observed when the high strength of concrete with chloride content is replaced by fine bottom ash with fine aggregate the outcome shows the chloride diffusion is reduced in the presence of high concrete strength in the bottom)
