Abstract

The invention belongs to the technical field of accelerators, and particularly relates to a concrete liquid accelerator. Aiming at problems in the prior art that the existing powdery accelerator has the disadvantages of low dissolving speed, difficult dispersion and the like, and can be only applied to dry spraying process construction; most of the powdery accelerators contain strong alkaline substances so that eyes and skin of construction workers are easily injured and concrete strength is easily reduced, a scheme is provided, wherein the concrete liquid accelerator comprises 35-45 parts ofaluminum sulfate, 3-9 parts of sodium fluoride, 6-12 parts of a defoaming agent, 7-10 parts of a stabilizer, 5-10 parts of glycerol, 10-15 parts of hydroxycarboxylic acid, 4-10 parts of a preservative, 5-12 parts of a thickener, 10-20 parts of a peculiar smell adsorbent and 35-55 parts of water. The concrete liquid accelerator is convenient to prepare, the dissolving speed is increased, the working efficiency is improved, workers and the environment are not damaged, the anti-corrosion performance of concrete is improved, and the strength of the concrete is enhanced.

Description

technical field [0001] The invention relates to the technical field of quick-setting agents, in particular to a liquid quick-setting agent for concrete. Background technique [0002] Concrete quick-setting agent is a chemical admixture that can make cement or concrete solidify quickly. It is sometimes called a coagulant. It is mainly used in shotcrete construction. Applied on the surface of concrete, the concrete can harden quickly and improve its early strength. [0003] Existing powder accelerators have disadvantages such as slow dissolution rate and difficulty in dispersing, and can only be applied to dry spraying process construction. Most powder accelerators contain strong alkaline substances, which are easy to cause damage to the eyes and skin of construction workers , and it is easy to reduce the strength of concrete. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the existing powdery quick-setting agents su...
