Sulphoaluminate cement-based accelerator as well as preparation method and application thereof
The invention belongs to the technical field of drilling of soil layers or rocks in the ocean engineering construction industry, and particularly provides a sulphoaluminate cement-based accelerator for ocean engineering concrete as well as a preparation method and application of the sulphoaluminate cement-based accelerator. The sulphoaluminate cement-based accelerator comprises sulphoaluminate cement clinker, fluorgypsum, sodium aluminate, sodium carbonate and aluminum sulfate, and the mass ratio of the sulphoaluminate cement clinker to the fluorgypsum to the sodium aluminate to the sodium carbonate to the aluminum sulfate is (50-70): (10-20): (5-10): (5-10): (10-20). The sulphoaluminate cement-based accelerator disclosed by the invention has a better rapid setting effect, the initial setting time can be as short as 3 minutes, and the final setting time can be as short as 6 minutes; and the mechanical property is good, the 1d compressive strength can be up to 10MPa or above, and the 28d compressive strength ratio can be up to 90% or above.
本发明属于海洋工程建筑行业的土层或岩石的钻进技术领域，具体提供一种海洋工程混凝土用的硫铝酸盐水泥基速凝剂及其制备方法和应用。硫铝酸盐水泥基速凝剂包括硫铝酸盐水泥熟料、氟石膏、铝酸钠、碳酸钠和硫酸铝，其中，硫铝酸盐水泥熟料、氟石膏、铝酸钠、碳酸钠和硫酸铝的质量比为(50～70)：(10～20)：(5～10)：(5～10)：(10～20)。本发明的硫铝酸盐水泥基速凝剂具有较好的速凝效果，初凝时间可短至3min，终凝时间可短至6min；且力学性能好，1d的抗压强度可高达10MPa以上，28d抗压强度比可高达90％以上。
