ABSTRACT

Recently, the geopolymer concrete is used in some structural applications as an alternative material to the well-known traditional concrete because it is considered an environmentally friendly construction material. The most attractive advantages of the geo-polymer concrete (compared to the traditional concrete) are: lower harmful emissions, converting a variety of waste streams into useful by-products, higher resistance to corrosion and fire, higher compressive and tensile strengths and improved durability properties. In this research, 24 different geopolymer concrete mixtures were produced using locally processed kaolinite minerals and fly ash as source materials where the alkaline liquid was a mixture of sodium hydroxide and sodium silicate. The main variables in the meta-kaolin based geopolymer concrete mixture were content of meta-kaolin, ratio of the silicate in the alkaline liquid to source material and the curing method. As for the fly ash based geo-polymer concrete mixture, the main variables were content of the fly ash in the mixture, ratio of the alkaline liquid to fly ash and molarity of the sodium hydroxide. Effect of these variables on both (slump and compressive strength) for all the 24 mixtures were experimentally investigated in details. The obtained test results concluded that: increasing of silicate/meta-kaolin ratio, content of meta-kaolin and hot curing regime will improve the compressive strength of meta-kaolin based geo-polymer concrete. Also, increasing the alkaline liquid ratio, morality of NaOH solution, and content of fly ash will improve the compressive strength of fly ash based geopolymer concrete.
