Study and experimental investigation of partial replacement of waste glass powder as cement in concrete

摘要

Cement Manufacturing industry is one of the Carbondioxide [co2 ] emitting sources to the atmosphere . To reduce this emission the .alternative material to be used in the concrete in which the glass is adopted .Glass is an economical and environmental friendly construction material . Glass is nonbiodegradable material not suitable for landfill . In this paper partial replacement of cementitious material in concrete in 10%,15%,20%. The replacement of glass powder decreases the unit weight and porosity by decreases in water absorption . The early consumption of alkalis by glass particles helps in reduction of alkali silica reaction . The workability of concrete is determined by using slump test and the crushing strength of aggregate is determined by using impact test .Therefore, the glass powder is used to some extent can replace the cement and contribute the strength development and characteristics of durability .
