High-performance underwater non-dispersible concrete
The invention relates to high-performance underwater non-dispersible concrete which comprises the following components in parts by mass: 450-750 parts of fine aggregate, 700-1050 parts of coarse aggregate, 350-450 parts of cement, 150-260 parts of water, fly ash, mineral powder, silica fume, a polycarboxylate superplasticizer and polyacrylamide for underwater non-dispersible concrete, wherein the polyacrylamide for the underwater non-dispersible concrete is a terpolymer and comprises an acrylamide structural unit, an acrylic acid structural unit and an allyl-A-D-galactopyranoside structural unit, and the molar ratio of the three structural units is (50-70): (15-25): (15-25). By adding the polyacrylamide flocculant of the concrete especially suitable for underwater construction into the concrete, the concrete has excellent dispersion resistance, flowability, compressive strength and water-land strength ratio, so that the concrete can meet the requirements of underwater construction and has excellent strength performance.
本申请涉及一种高性能水下不分散混凝土，包括细集料450‑750质量份、粗集料700‑1050质量份、水泥350‑450质量份、水150‑260质量份，还包括粉煤灰、矿粉、硅灰、聚羧酸减水剂、水下不分散混凝土用聚丙烯酰胺；其中，水下不分散混凝土用聚丙烯酰胺为三元共聚物，包括丙烯酰胺结构单元、丙烯酸结构单元和烯丙基‑Α‑D‑吡喃半乳糖苷结构单元，三种结构单元的摩尔比例为(50‑70):(15‑25):(15‑25)。通过在混凝土中添加特别适用于水下施工的混凝土的聚丙烯酰胺系絮凝剂，使得混凝土具有优异的抗分散性、流动性、抗压强度和水陆强度比，使得混凝土能够能够满足水下施工的要求，并具有优异的强度性能。
