Nanometer non-shrinkage repair concrete
The invention discloses nanometer non-shrinkage repair concrete which is quick in early strength, good in cohesiveness with a base body, high in compactness, free of cracking and resistant to corrosion. The nanometer non-shrinkage repair concrete comprises, by mass, 35%-45% of cement, 25%-42% of medium sand, 15%-25% of coarse aggregate, 0.5%-1% of high-efficiency slushing agent, 3-4% of expanding agent, 2%-5% of nanoscale ground calcium carbonate, 1%-2% of concrete nanometer slushing super high-early-strength agent and 1%-2% of rust inhibitor. The concrete nanometer slushing super high-early-strength agent comprises, by mass, 46%-52% of early-strength components, 26%-32% of slushing components, 6%-15% of rust inhibiting components, 4%-5% of retarding components and 6%-8% of nanoscale ground calcium carbonate.
