The Influence of Different Natural Fibers on the Mechanical Properties of Geopolymer
Geopolymers can effectively deal with construction waste disposal problems, achieving resource recycling and higher strength than normal cement concrete. However, natural defects make geopolymer concrete difficult to apply in actual construction. This paper aims to make up for the natural defects of geopolymers while maintaining environmentally friendly materials. The low-calcium fly ash and blast furnace refining slag powder are used as raw materials, sodium silicate and sodium hydroxide are used as alkali activators, and chopped natural fibers are added as reinforcing materials to prepare natural fiber reinforced low-calcium fly ash and blast furnace refining slag base. Polymeric composites were used to investigate the effects of different natural fibers on the workability, compressive strength, tensile strength, water absorption, shrinkage and microstructure of geopolymer composites.
