一种改性地质聚合物海工混凝土及制备方法
摘要：
本发明涉及一种改性地质聚合物海水海砂混凝土及制备方法，该混凝土按质量百分数计，包括：海水5%-15%、海砂10%-30%、碎石30%-55%、减水剂0.1%-1%、矿渣10%-30%、硅粉5%-10%、粉煤灰5%-15%、纤维0-5%、煅烧菱镁石5%-15%、激发剂0.1%-0.5%。相较于其他海水海砂混凝土在抗氯离子渗透性能良好的同时还具有良好的抗裂性，制备的改性地质聚合物混凝土不仅能够防止钢筋侵蚀，并且能够抵抗外界海水有害离子的侵入，在强度方面也有一定的提升，进一步提高混凝土结构的耐久性。
摘要（英）：

The invention relates to modified geological polymer seawater and sea sand concrete and a preparation method. The concrete is prepared from, by mass, 5-15% of seawater, 10-30% of sea sand, 30-55% of macadam, 0.1-1% of a water reducing agent, 10-30% of slag, 5-10% of silicon powder, 5-15% of pulverized fuel ash, 0-5% of fibers, 5-15% of calcined magnesite and 0.1-0.5% of an exciting agent. Comparedwith other seawater and sea sand concrete, the modified geological polymer marine concrete is good in chloride ion penetration resistance and further has good crack resistance, the prepared modifiedgeological polymer marine concrete can prevent rebar erosion and resist invasion of harmful ions of external seawater, the strength of the concrete is also improved to a certain degree, and the durability of a concrete structure is further improved.
