USAGE OF RED MUD IN GEOPOLYMER MORTAR MIXTURES

Popular techniques of waste treatment are often very expensive and difficult to access.Nowadays, billions tons valuable material deposited in landfills without using potential. The factthat five ten percent the total carbon dioxide emissions coming from civil engineering, actually theproduction cement, means that it is necessary find some alternative materials. Alkali-activated materials -geopolymers created order prevent emission use Geopolymersare result a chemical process called geopolymerization. They were developed promote fireprotection, but their numerous benefits observed during laboratory tests. Materials such as industrialby-products might be used binder because structure rich aluminosilicatecompounds. As well-known building materials, here, application different materialsmakes difference structure. During geopolymer mixtures production, binders andalkali activators required more steps than traditional materials: like blending materials,dissolving liquid phase, etc., end, few times lower when compared toothers mixtures. It clear greatest benefit ecological aspects.The paper presents results testing physical, mechanical, durability characteristics geopolymermixtures. Fly ash was primary material, while its partial replacement made with addition ofred mud. All mortar mixes meet basic requirements terms compressive flexuralstrengths.The continued on frost thaw up twenty-five cycles. can concluded coefficient ofresistance, flexural strength greater seventy-five only withfifteen red mud etalon sample. By calculating resistance parameter,it all samples fly redmud freezing thawing resistant
