Semirigidity activated leakproof paste
A semi-rigid and active technology, applied in other chemical processes, building components, building insulation materials, etc., can solve the problems of poor temperature difference adaptability and anti-aging performance, poor adhesion of dense structures, and inability to adapt to economic construction. Achieve the effects of strong anti-aging ability, good bonding performance and high cost performance

Problems solved by technology
[0002] At present, waterproof materials widely used in highways, bridges, houses, and underground projects usually fall into two categories: rigid and flexible waterproof materials, such as waterproof concrete, fiber concrete, modified asphalt, resin polymers, etc., waterproof concrete and fiber concrete and other rigid waterproof materials Due to the material's large porosity, compactness, and poor adhesion to structures, leakage will occur once micro-cracks occur; modified asphalt materials are better bonded to the original structure of structures, but the temperature difference adaptability and The anti-aging performance is poor, and the waterproof life is greatly limited; compared with polyester materials, the effect is better, but the construction is more complicated, the cost is high, and the application range is limited to a certain extent
At present, although there are many kinds of waterproof materials, there are few anti-seepage materials with good cost performance, simple construction technology, good waterproof performance, frost resistance, heat resistance and aging resistance, which obviously cannot meet the needs of economic construction.

Abstract
The invention discloses semi rigid activity anti seepage cream. It is made up activity micro-powder, asphalt, fiber and / or concrete, and admixture. Their proportioning weight ratios are 100-280, 50-200, 0.0.-0.10, and 0.03-0.5. The activity micro-powder is made up of fine concrete, slag micro-powder, fly ash initial powder, silicon ash, and sand. Its component weight rations are 30-60, 10-40, 10-40, 5-20, and 80-120. The formed product can be applied to anti seepage, anti-leak, and crack punish in high way, bridge, tunnel, and house. It has broad application industry field, and high efficiency economy.
