Thiocyanate-regulated micro-expansive cement-based self-leveling mortar and preparation method thereof
The invention discloses thiocyanate-regulated micro-expansive cement-based self-leveling mortar and a preparation method thereof, and belongs to the technical field of cement-based materials. The thiocyanate regulated and controlled micro-expansive cement-based self-leveling mortar is prepared from the following raw materials in parts by mass: 20 to 40 parts of a cementing material, 60 to 80 parts of fine aggregate, 1 to 3.04 parts of an ettringite growth control agent containing thiocyanate, 0.005 to 0.015 part of a water-retaining agent, 0.4 to 0.8 part of a water reducing agent and 0.4 to 0.6 part of redispersible latex powder, the gelling material is a material in which the molar ratio of sulfur to aluminum is (1.45-1.65): 1 and the total molar ratio of sulfur to ferro-aluminum is (1.05-1.35): 1. The micro-expansive cement-based self-leveling mortar disclosed by the invention is mortar of which the setting time is adjusted through the ettringite growth control agent, has the advantages of early strength, high strength, controllable setting, good volume stability and the like, and can meet the requirements of rapid construction, accelerated production efficiency and the like.
本发明公开了一种硫氰酸盐调控的微膨胀水泥基自流平砂浆及其制备方法，属于水泥基材料技术领域。本发明的硫氰酸盐调控的微膨胀水泥基自流平砂浆，包括以下质量份数的原料：胶凝材料20～40份、细骨料60～80份、含有硫氰酸盐的钙矾石生长控制剂1～3.04份、保水剂0.005～0.015份、减水剂0.4～0.8份和可再分散乳胶粉0.4～0.6份；胶凝材料为硫铝摩尔比为(1.45～1.65)：1，硫和铝铁的总摩尔比为(1.05～1.35)：1的材料。本发明的微膨胀水泥基自流平砂浆是一种通过钙矾石生长控制剂调节凝结时间的砂浆，具有早强高强、凝结可控、体积稳定性好等优点，可以满足快速施工、加速生产效率等要求。
