Composite mortar material and application thereof
The invention provides a composite mortar material and application thereof, and relates to the technical field of bridge repair. The composite mortar material provided by the invention is prepared from the following raw materials in parts by mass: 25 to 40 parts of cement, 0 to 10 parts of silica fume, 0.4 to 1.5 parts of expanding agent, 0.5 to 1.5 parts of early strength agent, 1.2 to 8 parts of fiber, 0.5 to 1 part of shrinkage reducing agent, 1 to 6 parts of rubber powder, 50 to 60 parts of quartz sand, 0.5 to 1 part of water reducing agent and 0.1 to 0.5 part of defoaming agent. The cement, the silica fume, the expanding agent and the early strength agent are adopted to form a composite multi-element gel system, and the rubber powder has an efficient organic bonding effect, so that the composite mortar material has excellent bonding strength; the fiber provides a tough component for the composite mortar material, and the water reducing agent can effectively disperse the cement and has a good steric hindrance effect.
本发明提供了一种复合砂浆材料及其应用，涉及桥梁修补技术领域。本发明提供的复合砂浆材料，按质量份数计，包括以下制备原料：水泥25～40份、硅灰0～10份、膨胀剂0.4～1.5份、早强剂0.5～1.5份、纤维1.2～8份、减缩剂0.5～1份、胶粉1～6份、石英砂50～60份、减水剂0.5～1份和消泡剂0.1～0.5份。本发明采用水泥、硅灰、膨胀剂和早强剂组成的复合多元胶凝体系，其中胶粉具有高效有机粘结作用，使复合砂浆材料具有优异的粘结强度；纤维为复合砂浆材料提供韧性组分，减水剂能够对水泥进行有效分散，且具有良好的空间位阻效应。
