Composite high-performance cement-based grouting material for repairing local diseases excited by carbamate and preparation method of composite high-performance cement-based grouting material
The invention belongs to the field of road engineering, and discloses a carbamate-excited composite high-performance cement-based grouting material for repairing local diseases, which is characterized by comprising the following components in parts by weight: 45-50 parts of cement; 20 to 25 parts of water; 2.0 to 2.5 parts of composite polyurethane; 0.9 to 1.0 part of nano silica fume; 2.3 to 2.5 parts of fine sand; 0.2 to 0.25 part of a water reducing agent; and 0.2 to 0.25 part of a defoaming agent. The invention further discloses a preparation method. The invention has the following main beneficial effects: the hydration reaction and the hydration speed are improved, and the formation of early strength is promoted; the strength and the interface bonding strength after hardening and the toughness and the stability of the grouting material are improved, the bubble content in the grouting material is reduced, the brittle fracture of a pavement is effectively reduced, the breaking strength of cement mortar is increased, the mixture is mixed at normal temperature, the required energy consumption is low, and no waste gas is discharged; and after hardening, the strength is higher, and the adaptability is better.
本发明属于道路工程领域，公开了一种氨基甲酸酯激发的局部病害修复的复合高性能水泥基灌浆材料，其特征在于，各组分的添加量按重量份数计为：水泥45~50份；水20~25份；复合聚氨酯2.0~2.5份；纳米硅灰0.9~1.0份；细砂2.3‑2.5份；减水剂0.2~0.25份；消泡剂0.2~0.25份。本发明还公开了制备方法。本发明具有以下主要有益效果：提高了水化反应和水化速度，促进了早期强度的形成；提高了硬化后的强度和界面粘结强度及灌浆料的韧性与稳定性，降低了灌浆材料中的气泡含量，有效减少了路面的脆性断裂，增加了水泥胶浆抗折强度，常温下拌和，所需能耗较低，无废气排出；硬化后较高的强度，适应性较好。
