Rapid permeation reinforcing material for concrete denudation reconstruction
The invention discloses a rapid permeation reinforcing material for concrete denudation reconstruction. The material is prepared from the following raw materials in parts by mass: 30-70 parts of lithium water glass with the fineness modulus of 6-12, 10-30 parts of potassium water glass with the fineness modulus of 4-8, 2-6 parts of an accelerant, 2-8 parts of a slow-release dispersing agent, 10-20parts of water-based resin, 8-16 parts of silicone oil emulsion, 0.1-0.3 part of an organic tin catalyst, 1-3 parts of an ether silicon defoaming agent and 50-100 parts of water. According to the rapid permeation reinforcing material, the concrete compactness can be increased in a short time, the strength of a concrete surface layer is improved, the bonding performance of a mortar repairing layerand original concrete is greatly improved, the disengaging risk of the laminated repairing structure under the action of periodic fatigue loads is reduced, the long-term effect of the repairing effect is ensured, and the method is suitable for rapid repairing of concrete denudation diseases caused by freezing and thawing, sulfate corrosion and the like and can also be used for concrete protection.
一种用于混凝土剥蚀修复的快速渗透增强材料，其特征在于：该材料由下列质量份数的原料组成：细度模数为6～12的锂水玻璃30～70份、细度模数为4～8的钾水玻璃10～30份、促进剂2～6份、缓释型分散剂2～8份、水性树脂10～20份，硅油乳液8～16份，有机锡催化剂0.1～0.3份，醚硅消泡剂1～3份，水50～100份。该快速渗透增强材料可在短时间内增加混凝土密实度，增大混凝土表层强度，大幅提高砂浆修补层与原混凝土的粘结性能，降低叠层修补结构在周期疲劳荷载作用下的脱开风险，确保了修复效果的长效性，适用于因冻融、硫酸盐侵蚀等造成的混凝土剥蚀病害的快速修复，也可用于混凝土防护。
