INORGANIC FIBRE REINFORCED GEOPOLYMER CONCRETE

Abstract

Geopolymer concrete (GPC) is a new green building material with low pollution, low energy consumption and high strength; however, it has the disadvantage of being brittle and prone to cracking. Studies have shown that the incorporation of inorganic fibres in GPC can enhance the toughness of GPC and inhibit the development of cracks. There is no clear uniformity in the existing literature on the effect of inorganic fibres to enhance GPC. In this paper, the research reports on the effect of inorganic fibres on the mechanical properties of GPC in recent years, and the prospects of their future research are discussed.
