Concrete structure self-compacting waterproofing agent as well as preparation method and application thereof

Abstract

The invention discloses a concrete structure self-compacting waterproofing agent as well as a preparation method and application thereof. The concrete structure self-compacting waterproofing agent isprepared from the following components in parts by weight: 10-12 parts of magnesium fluosilicate, 5-8 parts of a dispersing agent, 6-7 parts of ammonia water, 0.6-0.8 part of a preservative, 110-120 parts of water, 3-5 parts of molten aluminum, 3-5 parts of a defoaming agent and 4-6 parts of stearic acid. When the concrete structure self-compacting waterproof agent is applied, the concrete structure self-compacting waterproof agent only needs to be sprayed on the surface of concrete, the spraying amount is 0.2-0.4 kg / m <2>, with wetting kept for 0.3-0.4 h; the surface of the concrete fully absorbs the concrete hardening waterproof agent, and the concrete hardening waterproof agent can permeate by 0.8-1.2 cm; and still standing is conducted for 14-16 h, and a strength waterproof sealing effect can be shown.

Description

technical field [0001] The invention relates to the field of concrete waterproofing agents, in particular to a concrete structure self-compacting waterproofing agent and its preparation method and application. Background technique [0002] Concrete is a comprehensive material composed of sand, stone aggregate, cement, fly ash, mineral powder, and water. The cement stone formed through the grading and hydration of various raw materials is easy to produce pores and cracks to leak water. [0003] Concrete waterproofing agent should have the function of improving the impermeability and waterproofing of concrete, and at the same time have the effects of retarding, early strength, water reduction, and crack resistance, and can improve the workability of fresh mortar. It can replace lime paste and is suitable for the roof of one-story houses. Concrete, large-volume waterproof concrete, hydraulic concrete, waterproof mortar, etc. [0004] Although the waterproofing agents currently...

Problems solved by technology

[0004] Although the waterproofing agents currently on the market can improve the water resistance of concrete to a certain extent, their compatibility is poor and cannot meet the waterproof performance and construction needs of various types of concrete.
