High-ductility cement-based material for repairing hydraulic outlet works, and preparation method thereof
The invention discloses a high-ductility cement-based material for repairing hydraulic outlet works, and a preparation method thereof. The material comprises, by weight, 100 parts of cement, 25-150 parts of water, 50-250 parts of brown fused alumina, 20-450 parts of microspheres, 0.5-20 parts of nano-CaCO3, 0.1-5 parts of a water reducer, 0.95-15 parts of PVA fibers and 2-20 parts of ultrafine steel fibers. The high-ductility cement-based material for repairing hydraulic outlet works has the advantages of high impact and wear strength, high bonding strength with a matrix, high ductility, similar thermal expansion coefficient with concrete, consistence with deformation of the matrix concrete, simple and convenient construction process, and wide sources of raw materials.
