Abstract

The invention provides an aggregate treatment method for improving chloride ion permeability resistance of concrete. The method comprises the following steps: pre-wetting plastic steel fiber lightweight aggregate by using mineral admixture slurry or a concrete permanent setting solution. According to the technical scheme of the invention, the lightweight aggregate is pre-wetted by using the mineral admixture slurry or the concrete permanent setting solution, so that chloride ion diffusion parameters of plastic steel fiber lightweight aggregate concrete are effectively reduced, and the chlorideion permeability resistance of the plastic steel fiber lightweight aggregate concrete is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an aggregate treatment method for improving the chloride ion permeability resistance of concrete. Background technique [0002] Lightweight aggregate concrete refers to concrete with dry apparent density not greater than 1950kg / m3 prepared with light coarse aggregate, light sand (or ordinary sand), cement and water. Using a large number of waste resources such as slag, fly ash, silt, shale, etc. in construction, or directly using natural materials such as pumice or palm shells as concrete coarse aggregate, can effectively reduce environmental pollution, and has good economic benefits and actual use value. Compared with ordinary concrete, lightweight aggregate concrete effectively solves the shortcoming of concrete self-heaviness, so that modern buildings can continue to develop towards the direction of high-rise and long-span. Plastic steel fiber (polypropylene fiber...
