摘要
地质聚合物混凝土是一种新型绿色建筑材料,氯离子传输是影响其服役寿命的关键因素.本文在介绍地质聚合物混凝土氯离子传输机理的基础上,归纳总结了地质聚合物混凝土抗氯离子渗透性能试验方法的特点和局限性,介绍了地质聚合物混凝土抗氯离子渗透性能的影响因素,并对比了其与普通混凝土氯离子传输机理的区别.文章最后指出高温、冻融等单一因素影响下的地质聚合物混凝土氯离子传输模型、碱掺量和水玻璃模数对地质聚合物混凝土抗氯离子渗透性能的影响,以及氯离子的显色边界浓度的准确性等还有待进一步深入研究.
Abstract
Geopolymer concrete is a new type of green building material,and chloride ion transport is a key factor affecting its service life.Based on the introduction of the chloride ion transport mechanism of geopolymer concrete,this paper summarizes the characteristics and limitations of the test methods for the chloride ion permeability resistance of geopolymer concrete,introduces the interfering factors of the chloride ion permeability resistance of geopolymer concrete,and compares the chloride ion transport mechanism of ordinary concrete and geopolymer concrete.The article concludes by pointing out that the chloride transport model of geopolymer concrete under the influence of single factors such as high temperature,freeze-thaw,and etc.,the influence of alkali admixture and water glass modulus on the resistance of geopolymer concrete to chloride infiltration,as well as the accuracy of the color rendering boundary concentration of chloride ions are still to be further investigated in depth.
