Strength and Structural Properties of Geopolymer Concrete with Natural Fibers-A Review

Abstract

As the infrastructure development growing worldwide, the demand for ordinary Portland cement (OPC) increases exponentially. Studies revealed that the production of one ton cement releases one ton of CO2 to the atmosphere due to the calcinations of lime stone and combustion of fossil oil. The production of cement is highly energy intensive and it consumes a substantial amount of natural resources. Davidovits (1978) proposed that binders can be produced by polymeric reaction of alkaline liquid with alumino-silicate materials such as fly ash, blast furnace slag, rice husk etc., Geopolymer also has the ability to form a strong chemical bond with rock based aggregates. Fiber reinforced geopolymer concrete is relatively a new composite material in which fibers are introduced in the matrix as micro reinforced to improve the strength properties. This paper presents a new review on various research works done in the area of geopolymer concrete and the effect of fiber on their mechanical properties.
