Abstract

The invention relates to the technical field of building materials, and concretely relates to an impact-resistant and wear-resistant composite material for a hydraulic structure. The composite material is used for solving the problem of poorer impact resistance and wear resistance of a composite material for manufacturing concrete in the prior art. The composite material comprises 25-30 parts of P.042.5 cement, 2-5 parts of ultrafine silicon powder, 2-5 parts of granulated blast furnace slag, 3-5 parts of secondary fly ash, 60-70 parts of quartz sands, 5-10 parts of wear-resistant aggregate, 1-5 parts of a high-elastic modulus fiber, 0.5-1 part of a high-performance water reducing agent, 2-8 parts of a natural inorganic nano-material, 1-3 parts of nano-SiO2, 0.1-0.5 part of cellulose etherand 0.5-1 part of a pressing and smearing slipping agent. The composite material prepared from the components has effectively improved impact resistance and wear resistance, and has the properties ofwater resistance, seepage resistance, corrosion resistance, high fatigue resistance and the like.

Description

Technical field

[0001] The invention relates to the technical field of building materials, and more specifically to an impact-resistant and wear-resistant composite material for hydraulic structures. Background technique

[0002] At present, my country is the country with the largest number of dams built in the world, but because the rivers in our country contain a large amount of sediment, gravel, etc., high-speed, sand-bearing, and bed-loaded water flow makes 70% of the dam discharge structures in operation in my country exist. Different degrees of erosion and damage problems, and some are even very serious, have caused great losses to economic and social development.

[0003] With the development of water conservancy and hydropower, high-head and large-flow hydraulic structures are an inevitable trend. The erosion of buildings will become more and more prominent. This will become a thorny problem in the design, construction, operation and management of hydraulic structures. The ...
