AN EXPERIMENTAL STUDY ON STRENGTH PROPERTIES OF GGBS AND METAKAOLIN IN ADDITION WITH ALKALINE SOLUTION OF SODIUM HYDROXIDE AND SODIUM SILICATEAbstract
Today the world facing the is the environmental pollution In the construction industry mainly the production of Portland cement will causes the emission of pollutants results in environmental pollution. We can reduce the pollution effect on environment, by increasing the usage of industrial by-products in our construction industry. Some of the Pozzolanic materials like flay ash, Silica fume, Rice Husk ash, Metakaolin; Ground Granulated Blast Furnaces Slag (GGBS) are used as cementations materials. Among them the Ground Granulated Blast Furnaces Slag,(GGBS) which is the waste from, of iron manufacturing industry, which may be used as substitute of cement in concrete due to its inherent cementing properties. Geo-polymer concrete is such a one and in the present study, to produce the geo-polymer concrete the Portland cement is fully replaced with GGBS (Ground granulated blast furnace slag) and alkaline liquids are used for the binding of materials. The alkaline liquids used in this study for the polymerization are the solutions of Sodium hydroxide (NaOH) and sodium silicate (Na2Sio3). The objective of this paper is to study the effect of Metakaolin (MK) and ground granulated blast furnace slag (GGBS) on the mechanical properties of geo polymer concrete (GPC) at different replacement levels where the convectional concrete is fully replaced as an cement with met kaolin and the percentage of replacement levels are investigated up to 60%for metakaoline, 40%for GGBS. (MK50-GGBS50, MK40-GGBS60, MK30-GGBS70, MK20-GGBS80, MK10-GGBS90). Sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solution have been used as alkaline activators. In the
present investigation, it is proposed to study the mechanical properties viz. compressive strength, split tensile strength of Metakaolin and GGBS based geo polymer concrete. These properties have been determined for M40 mix design at different curing periods like 7, 14, 28, days and at ambient room temperature.
