Preparation method of heat-repairing concrete containing asphalt aggregate
A preparation method of heat-repairing concrete containing asphalt aggregate. The heat-repairing concrete includes following components, by weight: 50-500 parts of cement, 5-400 parts of asphalt granules, 0-120 parts of fly ash, 0-150 parts of mineral powder, 0-100 parts of other mineral blending materials or additives, 0-10 parts of a water reducing agent, 0-1200 parts of coarse aggregate, 200-1000 parts of fine aggregate and 130-220 parts of water. The heat-repairing concrete is wide in available range and can be used for preparing concrete in different strength grades, different working properties or other performances. The heat-repairing concrete can be heated for being repaired at any periods in use and is free of aging and spoiling. The repairing belongs to whole repairing, so that the heat-repairing concrete is good in repairing effect and can be repaired repeatedly. The employed asphalt repairing material does not release substances being harmful to cement hydration and has no adverse influence on development of early strength and later strength. The heat-repairing concrete is simple in preparation method, is simple in processes, is easy to use and is strong in practicability.
