Anti-crack reinforcing agent for concrete

Abstract

The invention discloses an anti-crack reinforcing agent for concrete. The anti-crack reinforcing agent is characterized by being composed of the following components in parts by weight: 5 to 10 parts of isopropanol, 3 to 12 parts of triethanolamine, 1 to 4 parts of sodium hydroxide, 1 to 3 parts of dextrin, 2 to 8 parts of tributyl ester, 8 to 20 parts of polypropylene fiber, 2 to 16 parts of basalt fiber, 10 to 30 parts of high efficient water reducer, and 4 to 10 parts of organic silicon reinforcing agent. By determining the content range of each component, a better synergetic effect can be achieved, and thus the reinforcing agent is enabled to have the multiple functions of preventing water seepage, freezing, and cracking, resisting impact force and wear, and reducing water. By adding the reinforcing agent into concrete, multiple functions of concrete, such as anti-crack performance, impact resistant property, waterproof performance, slump, workability, and the like are prominently improved.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to a crack-resistant reinforcing agent for concrete. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion by cementitious materials, granular aggregates (also known as aggregates), water, and admixtures and admixtures added when necessary. It is a kind of artificial stone that is uniformly stirred, densely formed, cured and hardened. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. C...

Problems solved by technology

[0003] Existing concrete reinforcements have relatively single functions, such as only waterproof function, or only anti-crack function, etc. Concrete admixtures with a single function can no longer meet the development of concrete technology at the present stage, and the current research focus in the field of concrete at home and abroad It has been tran
