High-strength grouting material with super-strong hydrophobicity and flexibility and preparation method thereof
The invention discloses a high-strength grouting material with super-strong hydrophobicity and flexibility and a preparation method thereof, and belongs to the technical field of grouting materials. The high-strength grouting material comprises the following components in parts by weight: 300-450 parts of cement, 350-500 parts of fine sand, 30-70 parts of silica fume, 56-115 parts of an additive, 50-150 parts of a polymer modifier, 1-10 parts of a water-soluble low-surface-energy material and 90-120 parts of water. The high-strength grouting material has super-high hydrophobic performance, can meet the requirements of ice coating prevention, corrosion prevention and the like of the fabricated building, prevents water from invading joints of the fabricated structure, avoids corrosion and freeze-thaw damage of structural members, and improves the durability of the fabricated building; and meanwhile, the high-strength grouting material has very high flexibility and crack resistance, the influence of non-structural components of the fabricated structure on stress transmission of the structural components under the earthquake action can be weakened, the structural components cannot be damaged due to stress concentration, and the force transmission path and the overall performance of the fabricated building under the earthquake action are protected.
本发明公开了一种具有超强疏水性和柔韧性的高强灌浆料及其制备方法，属于灌浆料技术领域。本发明包括以下组分：水泥300～450份、细砂350～500份、硅灰30～70份、外加剂56～115份、聚合物改性剂50～150份、水溶性低表面能材料1～10份、水90～120份。本发明不仅具有超强的疏水性能，能够满足装配式建筑防覆冰、防腐蚀等要求，阻止水分侵入装配式结构接缝处，避免结构构件发生腐蚀和冻融性破坏，提高装配式建筑的耐久性；同时具有很强的柔韧性能和抗裂性能，可以减弱地震作用下装配式结构非结构构件对结构构件受力传递的影响，使得结构构件不会发生应力集中而致结构构件的损坏，保护了装配式建筑在地震作用下的传力途径和整体性能。
