摘要:
在镍渣粉体中单掺或复掺NaOH、Na2SiO3、Na2CO3等碱激发剂，探究不同碱激发剂和H2O/Na2O摩尔比值变化对镍渣聚合物砂浆力学性能的影响规律，采用压汞测孔法对镍渣聚合物净浆的孔隙结构进行分析。结果表明，复掺Na2SiO3和Na2CO3条件下，H2O/Na2O摩尔比值位于22~24时，镍渣聚合物砂浆具有较低的孔隙率和较高的抗压和抗折强度。
Abstract:
Such alkali activators as NaOH, Na2SiO3 and Na2CO3were added into nickle-slag powder individually or in combination to investigate the effects of different alkali activator types and the change of molar ratios of H2O to Na2O on the mechanical properties of nickel-slag geopolymer mortar. The pore structure of nickel-slag polymer paste was analyzed by the method of mercury pressure measurement.Results show that the nickel-slag geopolymer mortar has a lower porosity and a higher compressive strength and flexural strength when mixed with Na2SiO3and Na2CO3 and the molar ratio of H2O to Na2O is located in the range of 22-24.
