Sodium citrate retarded alkali-activated slag geopolymer as well as preparation method and application thereof
The invention discloses a sodium citrate retarded alkali-activated slag geopolymer as well as a preparation method and application thereof. The sodium citrate retarded alkali-activated slag geopolymer is prepared from the following preparation raw materials: 926 to 1153 parts of a cementing material, 416 to 448 parts of an alkali activator, 280 to 306 parts of water and 8 to 16 parts of sodium citrate, wherein the cementing material is obtained by mixing and modifying slag and wollastonite in a mass ratio of (7-9): 1. According to the alkali-activated slag geopolymer prepared by the invention, the setting time can be effectively prolonged, the strength of the alkali-activated slag geopolymer is improved, the working performance and the mechanical performance are effectively balanced, and the technical bottleneck of application of the alkali-activated slag geopolymer in high-performance building materials is broken through. The coagulation time of the obtained sodium citrate retarded alkali-activated slag geopolymer is 15 min or above, the 7-day compressive strength is larger than or equal to 90 MPa, the preparation process is simple, and the sodium citrate retarded alkali-activated slag geopolymer has good application prospects and can be applied to high-performance building materials.
本发明公开了一种柠檬酸钠缓凝碱激发矿渣地聚物及其制备方法和应用，包括以下制备原料：胶凝材料926份～1153份、碱激发剂416份～448份，水280份～306份，柠檬酸钠8份～16份；其中，胶凝材料由质量比为(7～9)：1的矿渣与硅灰石混合改性处理得到。本申请制备的碱激发矿渣地聚物不仅能有效延长凝结时间，又提升碱激发矿渣地聚物的强度，有效平衡了工作性能和机械性能，突破了碱激发矿渣地聚物在高性能建筑材料中的应用的技术瓶颈。得到的柠檬酸钠缓凝碱激发矿渣地聚物凝结时间为15min以上，7天抗压强度≥90MPa，制备工艺简单，具有良好的应用前景，能应用于高性能建筑材料中。
