Abstract

The invention discloses a concrete waterproof agent. The concrete waterproof agent comprises the following chemical components in parts by weight: 0.2-0.8 part of calcium dodecyl benzene sulfonate, 10-30 parts of sulphoaluminate, 20-35 parts of sodium bichromate, 5-10 parts of zinc stearate, 0.25-0.4 part of hexadecyl triethoxysilane, 0.2-0.3 part of propyl triethoxy silane, 0.3-0.4 parts of polyvinylpyrrolidone, 0.2-0.3 part of polyoxyethylene fatty alcohol ester, 0.1-0.2 part of triolein, 0.2-0.8 part of polypropylene fiber and 25-40 parts of water. The concrete waterproof agent is high in penetration ability, good in hydrophobicity, low in corrosivity, waterproof and heat-insulating; through the adoption of the concrete waterproof agent, slope-making and leveling can be realized, and different functions of the concrete waterproof agent can be independently used according to requirements of different construction parts.

Description

technical field [0001] The invention relates to a concrete waterproofing agent, which belongs to the technical field of building waterproofing. Background technique [0002] Building waterproofing is the measures taken from the building materials and structure to prevent water from penetrating certain parts of the building. Waterproofing is mostly used in roofs, underground buildings, underground parts of buildings, inner chambers and water storage structures that need to be waterproofed. According to the different measures and means adopted, it can be divided into two categories: material waterproof and structural waterproof. Material waterproofing is to rely on building materials to block the passage of water to achieve the purpose of waterproofing or increase the ability to resist leakage, such as waterproofing of coiled materials, waterproofing of coatings, rigid waterproofing of concrete and cement mortar, and waterproofing of clay and lime soil. [0003] Concrete is ...
