Solid alkali-activated geopolymer cement mortar rapid repair cement pavement material and preparation method thereof
The invention discloses a solid alkali-activated geopolymer cement mortar rapid repair cement pavement material which is prepared by mixing water, a solid alkali activator, geopolymer cement powder, standard sand and an additive. The geopolymer powder is prepared by mixing high-calcium pulverized coal and superfine slag powder according to a mass ratio, and the solid alkali activator is a blended solid particle of analytically pure grade NaOH, Na2SiO3 and NaCO3. The solid alkali-activated geopolymer cement mortar material for rapidly repairing the cement pavement can solve the problems that conventional liquid alkali-activated materials are not easy to transport and store, inconvenient to construct on site and the like, and has a positive effect on popularization and application of alkali-activated cementing materials. According to the invention, the cement pavement can be repaired in a short time, the traffic can be quickly opened, the repair and maintenance time can be reduced, the bonding performance with the old cement pavement can be improved, and the structural life of the pavement can be prolonged.
本发明公开了一种固态碱激发地聚物水泥砂浆快速修补水泥路面材料，由水、固态碱激发剂、地聚物水泥粉料、标准砂、添加剂混合配置而成。所述地聚物粉料由高钙粉煤和矿渣微粉按质量配比混合制备而成，所述固态碱激发剂为分析纯级别NaOH、Na2SiO3及NaCO3共混固体颗粒。本发明固态碱激发地聚物水泥砂浆快速修补水泥路面材料能够解决常规液态碱激发不易运输和储存、现场施工不便等难题，对碱激发胶凝材料推广应用具有积极作用。本发明在能够在短时间内修补水泥路面并快速开放交通，减少维修和养护的时间，并能提高与旧水泥路面的粘结性能，延长路面的结构寿命。
