Problems solved by technology

[0004] The existing C30 recycled aggregate concrete can maximize waste utilization, save resources, and protect the environment under the premise of meeting the performance and durability of concrete. However, in waterproofing projects, due to the requirements of the environment and construction conditions, concrete is often used Structural waterproofing, waterproof concrete not only has strength requirements, but also has impermeability requirements, and in engineering projects in areas with low winter temperatures, concrete with impermeability requirements often also has antifreeze requirements, so a kind of impermeability and antifreeze C30 concrete is prepared is the problem to be solved

Abstract

The invention discloses an impervious frost-resisting C30 concrete and a preparation method thereof. The concrete comprises cement, fly ashes, an admixture, sands, crushed stones, water, a swelling agent and a frost-resisting agent; the swelling agent comprises gypsum, calcium oxide, calcium stearate, calcium sulphoaluminate, rosin, ethanol, polyacrylic emulsion, polyethylene fibers and a lotus leaf hydrophobic agent; the frost-resisting agent comprises glycerol, rubber powder, alunite powder, calcium lignosulphonate, sodium sulfate, ethanediol, water and a sodium carbonate solution. The preparation method comprises the steps of the preparation of a first mixture, the preparation of a second mixture, and the preparation of finished products. The C30 concrete has the advantages that the impervious and frost-resisting performance are good, and the strength level of the concrete reaches C30.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, it relates to an anti-seepage and anti-freeze C30 concrete and a preparation method thereof. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] In the prior art, the Chinese invention patent application document with the application number CN201610580759.0 discloses a C30 recycled aggregate concrete and its preparation method. The amount of each material in each cubic concrete of the C30 recycled a...
