Embodiment Construction

[0015] Below in conjunction with example the present invention is further described.

[0016] The cement-based osmotic crystalline waterproofing agent of the present invention comprises the following components by mass percentage: 25-50% of silicon micropowder; 5-15% of sodium silicate; 0-17% of bentonite; 32-48% of fly ash; Polypropylene fiber 0~1.2%; sulfonate superplasticizer 3~15%. The more optimal mass percentage is 30~45% silica powder, 5~12% sodium silicate, 0~12% bentonite, 35~45% fly ash, 0.2~1.2% polypropylene fiber, 6~12% sulfonate Water reducing agent.

[0017] Table 1 shows four examples of cement-based penetrating crystalline waterproofing agents.

Abstract

The invention relates to an inorganic cement capillary crystalline waterproofing agent and a production process thereof. The organic cement capillary crystalline waterproofing agent is prepared from silicon ash, sodium silicate, bentonite, pulverized fuel ash, polypropylene fiber and a sulfonate water reducer by a certain percentage proportion. The production process sequentially comprises the steps of compounding, feeding, mixing, inspecting, packaging and warehousing. The organic cement capillary crystalline waterproofing agent has the advantages of capillary crystalline, waterproofing performance, durability, denseness, leaking stoppage and the like and can be widely used for waterproofing systems comprising building outer walls, basements and the like, especially for negative side waterproofing systems.

Description

technical field [0001] The invention relates to a construction engineering material, especially a cement-based permeable crystalline waterproofing agent used for water-repelling and leak-repelling of the flat and vertical surfaces of concrete structures such as internal and external walls of building structures, bridge decks, tunnels, dams, highways, and underground buildings. and its production process. Background technique [0002] With the development of the construction industry and the increasing number of underground and dam projects, people have put forward higher and higher requirements for waterproofing of buildings and moisture-proof and anti-corrosion materials for underground projects. Building waterproof material is an important part of construction engineering, and its performance directly affects the service life and function of the building. Compared with traditional waterproof materials, cement-based permeable crystalline waterproof coatings have irreplacea...
