Preparation method of modified coral sand concrete
The invention relates to the technical field of concrete materials, and discloses a preparation method of modified coral sand concrete, which comprises the following steps: S1, preparing materials: 5-10 parts of glass fiber, 10-15 parts of cementing material, 50-60 parts of coral sand, 20-30 parts of seawater, 15-20 parts of cement, 2-4 parts of liquid expanding agent, 5-7 parts of antifreezing agent and 4-8 parts of hole sealing agent. The storage and transportation cost of concrete raw materials can be reduced, the timeliness of raw material supply is guaranteed, the prepared ultrahigh-performance seawater coral sand concrete is high in strength, good in volume stability and excellent in permeation resistance, the coral sand concrete can be used for a long time, the service life of the coral sand concrete is prolonged, and the cost is reduced. The compactness of the concrete can be improved, and the porosity of the concrete is effectively compensated and improved, so that the volume stability of the coral sand concrete is ensured.
本发明涉及混凝土材料技术领域，且公开了一种改性珊瑚砂混凝土的制备方法，包括以下步骤：S1：准备材料，玻璃纤维5‑10份、胶凝材料10‑15份、珊瑚砂50‑60份、海水20‑30份、水泥15‑20份、液体膨胀剂2‑4份、防冻剂5‑7份和封孔剂4‑8份。本发明不仅能够降低混凝土原材料的储运成本，保证了原料供应的时效性，并且制得的超高性能海水珊瑚砂混凝土强度高、体积稳定性好、抗渗透性能优异，使珊瑚砂混凝土长时间的使用，提高了珊瑚砂混凝土的使用寿命，而且能够提高混凝土的致密性，有效弥补和改善了混凝土的孔隙率，从而保证了珊瑚砂混凝土的体积稳定性。
