Waterproof concrete and preparation method thereof

Abstract

The invention discloses waterproof concrete and a preparation method thereof, wherein the waterproof concrete is prepared from the following components in parts by weight: 300 to 350 parts of cement,600 to 700 parts of fine aggregate, 900 to 1000 parts of coarse aggregate, 100 to 120 parts of an admixture, 8 to 10 parts of an additive, 25 to 30 parts of a waterproof agent and 130 to 150 parts ofwater, wherein the preparation method of the waterproof agent comprises: taking 40-60 parts by weight of modified basalt fiber and 5-7 parts by weight of disproportionated potassium rosinate, uniformly stirring, adding 30-40 parts by weight of a UEA expanding agent, 3-5 parts by weight of sodium dodecyl sulfate and 3-5 parts by weight of ferrous sulfate, and uniformly stirring to obtain the waterproof agent. The waterproof concrete provided by the invention has excellent water resistance, excellent permeability resistance and excellent acid corrosion resistance.

Description

technical field

[0001] The invention relates to the technical field of concrete, more specifically, it relates to a waterproof concrete and a preparation method thereof. Background technique

[0002] Concrete is generally cured by mixing cementitious materials, aggregates, water and admixtures. When ordinary concrete is cured and formed, due to the tiny cracks in the concrete itself and its capillary effect, under external forces such as water pressure, the concrete will Water seepage will affect its service life, so for underwater projects, specific waterproof concrete is required. Waterproof concrete refers to concrete with an impermeability level greater than or equal to P6 level, which is mainly used in underground engineering of industrial and civil buildings. According to its preparation method, it can be divided into four types: waterproof concrete with improved gradation method, ordinary waterproof concrete with increased cement content and superfine powder filler, ...
