摘要:

基于响应曲面通用旋转组合设计法，选择碱激发剂模数、碱激发剂浓度、激固比作为配比变量，制定了矿渣碱激发胶凝材料制备的试验方案.测试了矿渣碱激发胶凝材料的凝结时间、2h抗压强度，观察了试件的表面特性.通过数据处理得到了各配比变量与材料初凝时间、2h抗压强度的响应曲面，分析了各配比变量对材料初凝时间及2h抗压强度的影响规律.结果表明：当碱激发剂模数为10～14，碱激发剂浓度为25%～30%(质量分数)，激固比为050(质量比)时，各组分能充分发挥协同作用，使材料具有良好的早期性能，满足抢修工程应用的基本要求.

Abstract:

The preparation test scheme of alkali activated slag binder (AASB) was established based on response surface methodology(RSM), by using modulus(M), activator concentration(wAC) and activation solid ration(RAS) as design parameters. Setting time and compressive strength after 2h standard curing were tested; the surface characteristics were observed; the response surfaces of setting time and compressive strength were obtained respectively. The effects of design parameters on setting time and compressive strength were studied. The test result shows that when M is between 10 and 14, wAC is between 25% and 30% and RAS is 050, the synergy among each component can reach full potential. As a consequence, AASB can achieve good comprehensive performance and satisfy the operating requirement of emergency repair.
