Anti-permeation concrete mixture and construction method thereof

Abstract

The invention discloses an anti-permeation concrete mixture and a construction method thereof, aiming at solving the problems that an ocean environment contains a lot of chlorine ions, damages to steel bars in concrete and the concrete are caused and the use effect of anti-permeation concrete is influenced. According to technical scheme, the anti-permeation concrete mixture is prepared from the following raw materials in parts by weight: 250 to 420 parts of portland cement, 65 to 80 parts of fly ash, 650 to 850 parts of sand, 1000 to 1080 parts of crushed stones, 5 to 10 parts of a water reducing agent, 13 to 29 parts of a calcium sulfoaluminate expanding agent, 1 to 3 parts of other auxiliary agents and 160 to 190 parts of water; after the anti-permeation concrete mixture is cured, obtained concrete has a relatively good tolerance capability.

Description

technical field [0001] The invention relates to concrete, in particular to an anti-seepage concrete mixture and a preparation method thereof. Background technique [0002] Concrete generally refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, densely formed and cured . As a building material with a large amount and a wide range of use in the world, concrete has been widely developed in various countries and regions for its good mechanical properties, economy and adaptability to the environment. put forward higher requirements. [0003] Impermeable concrete refers to the concrete whose impermeability grade is equal to or greater than P6 grade. Impermeability concrete is divided into P6, P8, P10, and P12 according to different impermeability pressures. Impermeable concrete improves the pore structure ...

AI Technical Summary

Problems solved by technology

[0004] At present, the use of impermeable concrete in marine engineering is gradually increasing. The marine environment contains a large amount of chloride ions, which will cause damage to the steel bars inside the concrete and the concrete itself, affecting the use of impermeable concrete.
