Studies of polypropylene fibres’ effect on strength and workability of slag based geopolymer concrete

Abstract

The most useful, desirable, adaptable, emerging, reliable, and enduring construction material is concrete. After water Concrete is the most usable substance, and it requires a lot of Cement. The source of carbon dioxide pollution in the atmosphere, after the automobile is due to production of Ordinary Portland Cement and additionally, a significant quantity of energy was used to produce cement. The replacement of OPC or elimination of OPC in concrete is very much important to avoid global warming; A novel construction material called geopolymer concrete is created through the chemical reaction of inorganic molecules. The by-product of coal from a thermal power plant known as fly ash is widely accessible worldwide. Flyash is abundant in alumina and silica. This paper is aimed at studies on the strength and workability of conventional and geopolymer concrete. G40 grade of geopolymer concrete, which equivalent to M40 grade of conventional concrete has been developed by conducting various mixes. The conventional concrete specimen are casted and cured in water and in geopolymer concrete, these are cured with the help of oven for one day after one day rest period and rest of the days kept in atmosphere until testing. The test results have shown that the compressive strength is increased and workability is decreased with the addition of polypropylene fibres.
