Geopolymer concrete (GPC) is a new material in the construction industry, with different chemical compositions and reactions involved in a binding material.
Most polymeric fibers are semicrystalline. If the polymer forms a stable melt, the process is called melt spinning. For polymers that degrade prior to melting, the polymer is spun from a solution; if the solvent is evaporated, the process is termed dry spinning; if the solution is coagulated in a nonsolvent bath, the process is termed wet spinning.
In the process of cement hydration, the polymer produces a chemical reaction. Through the ion bond reaction and the entanglement of long molecular chains, the long chains of polymer molecules will cross-link each other between the micro-pores of cement soil, forming a network structure that penetrates the micro-pores inside the soil. ...
