Marine concrete, marine concrete impermeable agent, and preparation method and application thereof
The invention relates to the technical field of concrete anti-permeability agents, in particular to marine concrete, a marine concrete anti-permeability agent and a preparation method and applicationthereof. The anti-permeability agent is prepared from the following raw materials in percentage by weight: 8 to 55% of Portland cement clinker, 5 to 52% of high-iron sulfoaluminate cement clinker and10 to 40% of over-burnt dicalcium silicate. The main effective components of the anti-permeability agent are Portland cement clinker, high-iron sulfoaluminate cement clinker and over-burnt dicalcium silicate, and the anti-permeability of the marine concrete can be improved, and the marine concrete has the long-term mechanical property and anti-permeability. Meanwhile, on the basis of the hydrationrates of the Portland cement clinker, the high-iron sulfoaluminate cement clinker and the over-burnt dicalcium silicate, the particle sizes of the anti-permeability agent are matched to generate a synergistic effect, and the anti-permeability of the marine concrete is improved.
本发明涉及混凝土抗渗剂技术领域，尤其涉及一种海工混凝土、海工混凝土抗渗剂及其制备方法与应用。按重量百分比计，抗渗剂原料包括如下组分：硅酸盐水泥熟料8～55％、高铁硫铝酸盐水泥熟料5～52％、过烧硅酸二钙10～40％。本发明抗渗剂的主要有效成分为硅酸盐水泥熟料、高铁硫铝酸盐水泥熟料和过烧硅酸二钙的复合使用，不仅能够达到对海工混凝土的抗渗性的提升，并能够提供混凝土长久力学性能和抗渗性能。同时，本发明还基于硅酸盐水泥熟料、高铁硫铝酸盐水泥熟料、过烧硅酸二钙的水化速率的特点，使抗渗剂的粒径范围相互互补，协同发挥作用，提升海工混凝土的抗渗性。
