Investigation of Fly Ash Geopolymer Concrete Enhanced by Epoxy Resin & Glass Fiber

Abstract

A polymer binder is used to bond the aggregate in a matrix to create polymer concrete, a composite material. Due to its excellent impact resistance, quick curing time, and high compressive, tensile, and flexural strengths, it is becoming more and more popular as a new building material. This study examines a research project that aims to enhance basic comprehension of the subject matter and supply the information needed for widespread application. As a result, a comparison has been done between polymer concrete and traditional concrete using different amounts of resin and fibre. The mix design of M25 grade concrete is determined and the material amount is estimated in accordance with IS10262:2009. When carrying out an experimental programme Conventional concrete is tested using methods like compressive strength, flexural strength, and workability tests. Polymer resin concrete with fly ash and resin percentages of 3% and 5% is tested, and the results are compared to polymer fibre  concrete with glass fibre percentages of 0.5% and 1%.Polymer concrete was created in this experimental programme using glass fibre, epoxy resin, fly ash, and sand. The impact of fly ash and resin (binder) on the hardness, split tensile strength, flexural strength, and compressive strength of epoxy resin-based polymer filler is documented. Epoxy composites provide significant benefits over traditional structural materials, much like any other fiber-reinforced polymer composite. High specific strength, good toughness, strong insulating properties, and good corrosion resistance characterise these materials. Their employment in a variety of applications related to civil, aerospace, transportation, and marine engineering has been promoted by these qualities. Unfortunately, these materials have a substantial absorption of moisture, which can come from ambient moisture as well as direct immersion in regular or seawater while being used.
