An Investigation on Epoxy Resin-Coated Recycled Aggregate Concrete
摘要
Due to rapid industrialization and urbanization in the country, several infrastructure projects are coming up. This rapid development has led to an acute shortage of construction materials, and an increase in the dumping of waste materials. The purpose of this research is to determine the bonding properties of concrete that contains recycled material that has been coated with plastic and then submerged in epoxy resin. Epoxy resin concrete represents a novel expression of concrete composition. It possesses exceptional strength, a rapid rate of strength increase, excellent toughness, a short forming time, and effortless construction, among other qualities. Furthermore, it exhibits commendable performance against abrasion, water, chemical corrosion, and freezing. This study is founded on a comprehensive examination of the existing literature as well as previous research conducted by established experts in the field. A total of 32 cubes with a variety of compositions were cast. Of them, 16 cubes were designated for compressive strength testing, and the other 16 cubes were meant for tensile strength testing. There are four different concentrations of epoxy resin in the mixes: 5, 10, 15, and 20%. Additionally, there is a plastic content of 10 and 20%. As the normal and recycled aggregates were submerged in epoxy resin, the percentage of water that was absorbed by the aggregates decreased. According to the findings on the concrete mixtures, the utilization of epoxy resin in conjunction with both conventional and recycled aggregates has produced significant outcomes.
