Dynamic compressive properties of lightweight rubberized geopolymer concrete

Abstract

With the aim of incorporating sustainability into the ordinary concrete production, the construction industry has been utilizing solid waste materials to replace raw ingredients such as natural aggregates and cement. A practical solution to this is the cement-free geopolymer concrete in which alkali activators have chemical reactions with pozzolanic material and cementitious material, such as fly ash, silica fume, and blast furnace slag. The increasing landfill of waste tyre rubber has also resulted in environmental issues. One of the potential utilizations for waste rubber is to partially substitute the natural aggregates of geopolymer concrete. This study experimentally investigated the ef..
