Abstract

The invention relates to the technical field of building materials, and discloses rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete which is characterized in that the rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete comprises the following components: 400 to 500 parts of cement, 100 to 180 parts of water, 1200 to 1300 parts of stone, 500 to 600 parts of sand, 10 to 30 parts of an expanding agent, 0.5 to 2.5 parts of a water reducing agent, and 10 to 30 parts of waterproof nano powder, and the waterproof nano powder comprises the following components: mica powder, hydrophobic perlite powder, dimethyl silicone oil, a silane coupling agent and a surfactant. According to the rigid waterproof, freeze-thaw-resistant, corrosion-resistant and self-compacting high-performance concrete and the preparation method thereof, the waterproof nano powder is added, and the waterproof nano powder has a strong hydrophobic effect and a unique non-metal sheet structure, so that occlusion and connection among coarse and fine aggregates of the high-performance concrete can be effectively promoted, the contact area of a microstructure is enlarged, the porosity is reduced, and the compactness is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a rigid waterproof, freeze-thaw-resistant, anti-corrosion, self-compacting high-performance concrete and its preparation method*. Background technique [0002] With the development of science and technology, the construction industry is becoming more and more developed, high-rise buildings, railways, highway bridges, airports, subways, tunnels, urban underground pipe corridors, large storage warehouses, ports, docks, island construction, etc., are all based on High-performance concrete is the main building material. High-performance concrete looks like a whole. Its interior is full of large and small pores and defects. Water enters into it, and various corrosive ions enter it with the help of water, resulting in high-performance concrete. Various damage forms and defects, such as water seepage, freeze-thaw damage, corrosion damage, etc., greatly reduce the actual life ...
