Strength Properties of Fly Ash Based Geopolymer Concrete with Sea Sand
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 7
Abstract
The production of every ton of cement contributes to production of one ton of CO2. With the development of infra activities, the power sector activities are also increasing. The coal based power plant produces huge quantity of fly ash, which creates its disposal problems. However to some extent, the fly ash is used as partial substitution to cement. The alkali activated fly ash concrete (Geopolymer Concrete) proposed by Devidovits, shows considerable promise for application in construction industry as an alternative to the portland cement for precast concrete. Day by day the scarcity of river sand is big problem arrising to construction industry. On the other hand the sea sand is availibile in huge quantity, but the presence of salt and chloride affects strength and durability of cement concrete. In present experimental work the sea sand (Treated and untreated) is used as an alternative to river sand and studied the properties of cement concrete and geopolymer concrete. The results show that the untreated sea sand affects the compressive strength in geopolymer concrete same as cement concrete but treated sea sand gives similar results as of river sand concrete.
