Concrete compaction reinforcing agent
The invention relates to a concrete compaction enhancer, which is a liquid material and comprises the following components in percentage by mass: 20.0 to 50.0 percent of modified octyltriethoxysilane emulsion, 2.0 to 5.0 percent of cucurbituril, 1.0 to 4.0 percent of thermoplastic hollow high-molecular polymer microspheres and 41.0 to 77.0 percent of water. The concrete densification reinforcing agent disclosed by the invention is extremely good in waterproofness, and the water absorption ratio can be reduced to 0.8%; the reinforcing effect is obvious, and the 28-day compressive strength is increased by 136%; the expansion rate is large, the elasticity is good, the maximum expansion is 32 times, the risk of spalling caused by excessive addition is avoided, meanwhile, long-time moisturizing maintenance is not needed, the construction period is shortened, and the manufacturing cost is reduced; the temperature rise of the concrete is inhibited by about 10-16 DEG C, and the influence of overhigh temperature rise and overlarge temperature gradient of mass concrete on the volume stability, temperature crack and durability of the concrete is greatly improved.
本发明涉及一种混凝土密实增强剂，为液体材料，按质量百分比包括以下组分：改性辛基三乙氧基硅烷乳液20.0‑50.0％，葫芦脲2.0‑5.0％，热塑性空心高分子聚合物微球1.0‑4.0％，水41.0‑77.0％。本发明的混凝土密实增强剂，防水性极好，吸水率比可降至0.8％；增强作用明显，28天抗压强度增加136％；膨胀倍率大弹性好，最高膨胀32倍，却又没有过量添加引起胀裂的危险，同时无需长时间保湿养护，缩短工期降低造价；抑制混凝土温升约10‑16℃，极大程度改善大体积混凝土因温升过高、温度梯度过大对混凝土体积稳定、温度裂缝及耐久性的影响。
