EXPERIMENTAL STUDY ON PLASTIC FIBER REINFORCED FLYASH BASED GEOPOLYMER CONCRETE

In this experimental study, thermal power plants accessible waste material fly ash is used as geopolymer material. Here testing has been done to study the properties of geopolymer concrete using fly ash as the most important binding resource. Due to its resistance of corrosion ordinary Portland cement is less durable than geopolymer concrete. High calcium fly ash will produce more carbon dioxide emissions to reduce these emissions we have preferred to use low calcium fly ash. In this experimental study, we have used two alkaline liquids as binders, sodium hydroxide (12M) and sodium silicate. These are useful for polymerization process. A mix proportion for geopolymer concrete is different from normal concreteand was designed by assuming the density of geopolymer concrete as 2400 kg/m3. This experimental study describes the effect of polypropylene fibers in geopolymer concrete. An experimental work has been carried out on cubes, cylinders and prisms to know the various strengths. The polypropylene fibers were added with five different percentages (0%,0.75%,1.5%,2.25%,3%). The strength parameters were determined for various ages of concrete.
