ABSTRACT

This research paper depict thatconcrete is verycfrequently used building constructioncmaterial with yearlycusage increasing onecmeter cube perccapita. In the recentcdecade there is drasticcincrease in thecstudy of concrete withcemphasizing on sustainablecconcrete due tocheavy degradation ofcenvironment this causeccontribution in globalcwarming. The presentcresearch work iscon the sustainable concretecwith glass sand withcan ultimate goalcto contribute incthe building material andcconstructionsectorccause by sustainablecdevelopmentofcconcrete. The presentcinvestigation is done bycusing waste glass as acreplacement of finecaggregate in concrete. All thecproperties of fine aggregatecwere analysed oncglass sand for the sustainabilitycof glass sandcin concrete andcmortar and the bothcare cement based. Allcthe test that werecperformed to analysedcthe suitability of glasscsand in cementcconcrete and mortar wascfound to be harmlesscand does not affectcthe person in contactcor the structure andcthis cause the glasscsand to be use as a replacementcof fine aggregate uptoc100%. This study alsocemphasizing on alkalicsilica reaction of glasscsand in cementcconcrete with particlecsize distribution and contentcof glass sand incconcrete along withccolour of glass and theceffect cause due tocit in concrete andcthey are investigatedcthoroughly and it wascfound that he glasscsand of particlecrange between 1.18 toc2.36 mm was suitablecand there is noceffect of colour ofcglass in concrete withcthe alkali silica reactioncexpansion. Different alkalicsilica reaction mitigationcmethods were usedcfor the investigation ofcalkali silica reactioncwhich basically includecthe replacement ofccement by supplemcentarycementitious material suchcas fly ash orcadding of lithium orcnaturalreinforcementcsuchsafiber reinforcement.
