Anchor sealing mortar for precast concrete and preparation method of anchor sealing mortar
The invention discloses a composition for anchor sealing of a prestressed concrete prefabricated part. The composition is prepared from the following components in parts by mass: 100 parts of cement, 50 to 250 parts of fine aggregate, 3 to 25 parts of mineral admixture, 0.1 to 10 parts of polymer, 0.1 to 5.0 parts of modified super activated carbon, 0.1 to 1.0 part of dispersing agent, 0.1 to 2.0 parts of expansion component, 0.1 to 1.0 part of plastic agent, 0 to 1.2 parts of early strength agent, 0.1 to 1.5 parts of retarding component and 0.1 to 0.5 part of defoaming agent, wherein the modified super activated carbon is mainly prepared from petroleum coke, an activating agent and an activating auxiliary agent as raw materials. The invention also provides mortar for anchor sealing of the pre-stressed concrete prefabricated part, which comprises the composition and water, and a preparation method of the mortar. The anchor sealing mortar provided by the invention has the advantages of good interface cohesiveness and matching performance, small dry shrinkage after hardening, high volume stability, good anti-seepage performance, frost resistance, fatigue performance and durability and the like.
本发明公开了一种用于预应力混凝土预制件封锚的组合物，包括如下质量份的组分：水泥100份，细骨料50份～250份，矿物掺合料3～25份，聚合物0.1～10份，改性超级活性炭0.1～5.0份，分散剂0.1份～1.0份，膨胀组分0.1份～2.0份，塑性剂0.1份～1.0份，早强剂0～1.2份，缓凝组分0.1份～1.5份，消泡剂0.1～0.5份；其中，所述改性超级活性炭主要以石油焦、活化剂和活化助剂为原料制备得到。本发明还提供包括上述组合物和水的预应力混凝土预制件封锚用砂浆及其制备方法。本发明提供的所述封锚砂浆具有界面粘结性和匹配性好，硬化后干缩小、体积稳定性高，抗抗渗性能、抗冻性能、疲劳性能和耐久性能好等优点。
