Ultra-high performance concrete mixed with seawater and prepared from full coral aggregate and preparation method thereof
The invention discloses ultra-high performance concrete mixed with seawater and prepared from full coral aggregate. The concrete comprises cement, silica fume, slag, micro-beads, coral fine sand, coral medium sand, coral coarse sand, polyvinyl alcohol fiber, polypropylene fiber, a polycarboxylate superplasticizer and seawater in a weight ratio of 1: (0.38-0.41): (0.23-0.26): (0.092-0.13): (0.38-0.42): (0.99-1.13): (0.2-0.22): (0.008-0.01): (0.026-0.028): (0.038-0.041): (0.38-0.41). The invention further discloses a preparation method of the ultra-high performance concrete mixed with seawater and prepared from full coral aggregate. The concrete provided by the invention not only has good mechanical properties and durability, but also has the characteristics of low self-contractibility and high compactness.
本发明公开了一种海水拌制、全珊瑚骨料的超高性能混凝土，包括如下原料及其重量比：水泥、硅灰、矿渣、微珠、珊瑚细砂、珊瑚中砂、珊瑚粗砂、聚乙烯醇纤维、聚丙烯纤维、聚羧酸减水剂和海水的重量比为1：0.38～0.41：0.23～0.26：0.092～0.13：0.38～0.42：0.99～1.13：0.2～0.22：0.008～0.01：0.026～0.028：0.038～0.041：0.38～0.41。本发明还公开一种海水拌制、全珊瑚骨料的超高性能混凝土的制备方法。本发明既具有良好的混凝土力学性能和耐久性，又具有较低自收缩性和高致密性的特点。
