Problems solved by technology

The reason is that the usual anti-corrosion materials are not suitable for special harsh environments such as desert salt lake areas, especially in environments with heavy or ultra-saline soil, underground heavy brine, strong freeze-thaw, strong ultraviolet rays, strong windy sand with salt, and large temperature differences.

Abstract

The invention provides an anti-degradation complexing material for concrete structures of salinized soil regions, which is suitable for preventing the concrete structures from degradating in the various environments, particularly in the environments with heavily and super salinized soil, underground heavy bittern, strong freezing and thawing, intense ultraviolet, salt-containing dust storms, large temperature difference and the like. The anti-degradation complexing material comprises Portland cement or ordinary Portland cement, fine sands with 80-180 meshes, calcined lime, slaked lime, coal ash, slag micro powder, silicon dioxide ultrafine powder, sodic smectite powder, diatomaceous earth, instant solid water glass, alunite annealing powder, zinc fluosilicate, sodium polyacrylate, hydroxypropyl methyl cellulose, zinc stearate, a naphthalenesulfonate methanal condensation compound, cane molasses powder, citric acid crystals and organosilicone antifoaming agents. The anti-degradation complexing material for the concrete structures of the salinized soil regions can repair concrete structure gaps after encounters water, greatly enhances the durability and anti-degradation performance of the concrete structures and is suitable for the various environments.

Description

technical field [0001] The invention relates to a concrete structure building material, in particular to an anti-deterioration complexing material for concrete structures in saline soil areas. Background technique [0002] In the past, many scholars and experts at home and abroad believed that "concrete is a durable structure". In the former Soviet republics and China's desert salt lake area and its vicinity, anti-corrosion materials used in previous projects (hot asphalt, Russian polysulfide rubber, Russian formaldehyde acetone, Russian ammonium carbonate formaldehyde, Russian diene styrene emulsion, Russian alkyd resin, Perchlorethylene, epoxy anti-corrosion coating, low-density polyethylene, high-chlorinated polyethylene, calcium naphthenate soap, American concrete permanent fluid, scale coating, acrylic polyurethane coating, Russian X∏-734, epoxy resin Coating, etc.) is not obvious for the anti-deterioration effect of concrete structures in strong and over-saline soil a...
