Influence of the dosage of excitant on the strength and curing Pb2+ properties of the material based on CFBC ash geopolymer

Abstract

Abstract:

The utilization of a large amount of deposited coal ash from circulating fluidized bed, which is the CFBC ash geopolymer by using CFBC ash as raw material. The study is carried out for the effects of alkaline excitation agent on the strength of the geopolymer, and the curing properties of Pb2+ with inductively coupled plasma method. Research results show that when the excitant of n(Na2O)/n(SiO2) is 0.27, the CFBC ash geopolymer's intensity reaches maximum, when n(Na2O)/n(SiO2) is higher than 0.27, the intensity is almost constant, the solidify of Pb2+ with CFBC ash geopolymer grows with the increase of the amount of excitant.
