Geo Polymer Concrete with the Replacement of Granite Aggregate as Fine Aggregate

Eliyas Basha Shaik | Sreenivasulu Reddy


Abstract: Disposal of granite fines from the polishing industries is a major problem. As the granite polished powder is reactive it cannot be disposed into land. When dumped on land, these wastes adversely affect the productivity of land due to decreased porosity, water absorption, water percolation etc. They cause serious environmental and dust pollution and require vast area of land for their disposal. The production of cement concrete accounts to about 5 % of the man made pollution for global warming. During the polishing operations the amount of granite powder waste retained and passing through 150 are 12 % and 88 % respectively. The granite waste because of its fineness and size it can be effectively used as a replacement of sand. The strength of geo polymer concrete increases with the increase in the alkalinity of NaOH. Previous investigations on introduction of granite fines into ordinary concrete showed positive results at an optimum replacement of sand at 15 %. An attempt was made to introduce granite aggregate into geo polymer concrete as it increases the alkalinity of geo polymer concrete as well as it`s grading of sand. The granite aggregate was replaced in percentages various tests such as split tensile strength, compressive strength and flexural strengths were tested and compared with basic mix.
