Utilisation of Sustainable Materials in Geopolymer Composites– A Review

Abstract. Geopolymer composites made from sustainable ingredients which are used to make ecofriendly concrete in the infrastructure sector. The dramatic increase in infrastructure growth around the world demonstrates the daily demand for cement production. This study provides an overall view of research on the use of materials and the performance of geopolymer matrix based on strength and durability. Unlike cement, the reutilization of industrial by-products reduces greenhouse gas emissions during manufacture. Hence geopolymers can contribute to a better alternative to Portland cement. Natural raw materials, agricultural waste, and industrial waste by products from diverse industries are used as composite filler / binder materials in geopolymer matrix to improve workability , durability and reducing geopolymer concrete manufacturing costs. With the help of various curing procedures, the compressive strength of geopolymer concrete can be increased in a short amount of time. It has also been discovered that adding fibres to geopolymer concrete improves tensile strength, lowering the cost of structural maintenance.
