Embodiment 1

[0010] A concrete glue reducer, the proportioning of each component in the glue reducer is as follows by weight: 100 parts of melamine, 400 parts of formaldehyde, 400 parts of water, and 100 parts of salicylic acid.

Embodiment 2

[0012] A concrete glue reducer, each component proportioning by weight in the glue reducer is as follows: 120 parts of melamine, 480 parts of formaldehyde, 300 parts of water, 100 parts of salicylic acid.

[0013] The use of the glue reducer reduces the concrete cost and improves the performance of the concrete under the premise that the strength remains unchanged.

Abstract

The present invention discloses a concrete glue reducing agent, which is characterized by comprising, by weight, 100-120 parts of melamine, 400-500 parts of formaldehyde, 300-400 parts of water, and 80-100 parts of salicyl acid. With the glue reducing agent of the present invention, under the premise of maintaining of the strength, the concrete cost is reduced, and the concrete performance is improved.

Description

technical field [0001] The invention relates to a concrete glue reducer capable of reducing the amount of cementitious materials used in concrete. Background technique [0002] Pumping is the main method of concrete construction. In order to meet the requirements of pumping, that is, high fluidity and high workability, the amount of cementitious materials in concrete is relatively high, generally above 350kg / m3. The high amount of cementitious material makes concrete more prone to cracking, especially in the case of low water-gel ratio, this phenomenon is more serious, and cracks are more likely to occur, which affects the construction quality of concrete. Contents of the invention [0003] The purpose of the present invention is to provide a concrete glue reducer, which can reduce the cost of concrete and improve the performance of concrete under the premise that the strength remains unchanged. [0004] The object of the present invention is achieved through the followin...
