High-performance seawater and sea sand concrete as well as preparation method and application thereof
The invention discloses high-performance seawater and sea sand concrete as well as a preparation method and application thereof. The concrete is prepared from the following raw materials in parts by weight: 20 to 25 parts of seawater, 70 to 80 parts of cement, 10 to 15 parts of micro-silica fume, 10 to 20 parts of ultrafine beads, 115 to 125 parts of sea sand, 210 to 220 parts of gravel, 0.8 to 1.2 parts of a high-efficiency water reducing agent, 0.03 to 0.05 part of a retarder, 0.07 to 0.10 part of a polyether modified organic silicon defoaming agent and 0.01 to 0.02 part of a nonionic surfactant air entraining agent. The retarder is a composite retarder composed of cane sugar, citric acid and sodium tripolyphosphate according to the weight ratio of (3-5): (2-3): (1-3). The initial setting time of the concrete is prolonged, and construction is more convenient; and meanwhile, small bubbles are introduced, so that the strength and the penetration resistance of the concrete are further improved, the quality is stable, and the concrete is widely applied to marine building structures.
本发明公开了一种高性能海水海砂混凝土及其制备方法和应用。本发明包括以下原料：海水20‑25份，水泥70‑80份，微硅灰10‑15份，超细微珠10‑20份，海砂115‑125份，碎石210‑220份，高效减水剂0.8‑1.2份，缓凝剂0.03‑0.05份，聚醚改性有机硅消泡剂0.07‑0.10份，非离子型表面活性剂类引气剂0.01‑0.02份；缓凝剂为蔗糖、柠檬酸和三聚磷酸钠按照重量比为3‑5:2‑3:1‑3组成的复合缓凝剂。本发明延长了混凝土的初凝时间，施工更加便利；有效消除了大气泡，同时还引入了微小气泡，进一步提高了混凝土的强度和抗渗透性能，质量稳定，在海洋建筑结构中得到了广泛应用。
