Low-heat seawater-resistant cement and preparation method thereof
The invention relates to the technical field of cement, in particular to low-heat seawater-resistant cement and a preparation method thereof. The low-heat seawater-resistant cement is prepared from the following raw materials in parts by mass: 0-25 parts of fly ash, 61-90 parts of granulated slag powder and 9-15 parts of an exciting agent. The invention also discloses a preparation method of the low-heat seawater-resistant cement. The low-heat seawater-resistant cement disclosed by the invention has excellent properties of low hydration heat, high fracture resistance and compressive strength, and excellent resistance to corrosion of sulfate, chlorine salt and seawater, has the compressive strength loss rate of less than 7% in 150 times of cycle freezing and thawing, can be applied to ocean engineering foundation reinforced concrete and mortar, and has the characteristics of energy conservation, consumption reduction, waste utilization and environmental protection.
本发明涉及水泥技术领域，尤其涉及一种低热抗海水水泥及其制备方法。低热抗海水水泥由以下质量份数的原料制成：粉煤灰0～25份、粒化渣粉61～90份和激发剂9～15份。本发明还公开了上述低热抗海水水泥的制备方法。本发明的低热抗海水水泥具有优异的低水化热、高抗折和抗压强度性能，还具有优异的耐硫酸盐、氯盐、海水腐蚀的性能，150次循环冻融抗压强度损失率＜7％，可应用于海洋工程基础配筋混凝土及砂浆，具有节能降耗、利废环保的特点。
