Experimental Study on Replacement of Cement Using Silica Fume and Fine Aggregate Using Glass Powder

Abstract

Increase in population results in increase in usage of materials which cause much pollution to environmental surroundings if not disposed properly. Replacement of costlier building material by disposable waste material is one of best engineering practice in construction. In this paper replacement of cement using silica fume is done up to 20% and replacement of fine aggregate using glass powder is done up to 40% also silica fume and glass powder are replaced by 15% and 20%.compressive strength for replaced materials and conventional concrete is studied for 7thday and 28th day. From test result it is concluded that glass powder and silica fume is better effective replaceable materials which is cost effective and eco-friendly.

A Step towards Sustainable Concrete with Substitution of Plastic Waste in Concrete: Overview on Mechanical, Durability and Microstructure Analysis

“…The reason for the increase in STS of silica fumecontaining concrete mixes was the same as for the increase in compressive strength [37]. Silica fume has been shown to boost the STS of concrete in previous experiments [12,[72][73][74][75][76][77].…”

A Step towards Concrete with Partial Substitution of Waste Glass (WG) in Concrete: A Review

“…A study showed that, at 10% replacements, the compressive strength increased by about 31%, 16%, and 9% at 7, 14, and 28 days of curing for the reference concrete, respectively [ 77 ]. Similarly, a study reported that compressive strengths at 7- and 28-days curing are about 3 to 4% higher than conventional concrete at 15% replacement of waste glass with cement [ 78 ].…”

“…The research was carried out on partial cement replacement with the waste glass in concrete at 0%, 5%, 10%, and 15%. Results indicated that concrete split tensile strength was improved up to 10% replacement cement with waste glass [ 77 ]. A researcher concluded that the split tensile strength of concrete increased with up 10% substitution of waste glass and then decreased gradually, having maximum strength at 10% substitution of waste glass [ 60 ].…”

“…Seong et al [ 83 ] observed 95% more than compared to the reference strength. Ahmad et al [ 49 ] Vandhiyan et al [ 77 ] and Tamanna et al [ 76 ] observed 55%, 60%, and 45% more split tensile strength compared to the reference strength. The various differences in compressive strength with respect to different researchers are due to changes in mix design, water-cement ratio, and environmental aspects such as temperature and humidity, etc.…”
