Super-early-strength grouting material capable of being used in harsh environment as well as preparation method and application of super-early-strength grouting material
The invention relates to a super-early-strength grouting material capable of being used in a harsh environment and a preparation method and application thereof, and the super-early-strength grouting material comprises the following components in percentage by weight: 30-40% of Portland cement; 2-8% of silica fume; 2-8% of amorphous calcium aluminate; 1-4% of natural anhydrite; 45-60% of wear-resistant aggregate; 0.1 to 0.5 percent of a water reducing agent; 0.03 to 0.05 percent of a coagulation accelerator; 0.03 to 0.05 percent of a retarder; 0.03 to 0.05 percent of an expanding agent; and 0.02 to 0.04% of a defoaming agent. According to the invention, the micro-nano material is used as an early strength agent and is added into the grouting material taking the silica cement as a main cementing material, so that not only can the macroscopic mechanical properties of the grouting material be improved, but also the wear resistance and corrosion resistance of mortar are improved.
本发明是关于一种可用于严酷环境下的超早强灌浆料及其制备方法和应用，以重量百分比计，其包括：硅酸盐水泥30‑40％；硅灰2‑8％；非晶态铝酸钙2‑8％；天然硬石膏1‑4％；耐磨骨料45‑60％；减水剂0.1‑0.5％；促凝剂0.03‑0.05％；缓凝剂0.03～0.05％；膨胀剂0.03～0.05％；消泡剂0.02～0.04％。本发明以这种微纳米材料作为早强剂，添加到以硅水泥为主要胶凝材料的灌浆料中，不仅能够提高灌浆料的宏观力学性能，而且改善了砂浆的耐磨和防腐蚀性能。
