Environment-friendly concrete water reducer and preparation method thereof

Abstract

The invention provides an environment-friendly concrete water reducer. The concrete water reducer comprises the following components in parts by weight: 30-40 parts of a triethanolamine oleic soap-based polyacrylic acid copolymer, 10-15 parts of modified activated clay, 5-10 parts of 4-aminophenyl fucoside, 4-6 parts of polyether amine, 10-15 parts of isopropanol and 30-40 parts of water, whereinthe triethanolamine oleic soap-based polyacrylic acid copolymer is prepared by copolymerization of triethanolamine oleic soap, (2R,3S,4S)-rel-2-carboxyl-4-(1-methylvinyl)-3-pyrrolidine acetic acid, sulfo succinic acid-1-(2-propenyl)-4-tridecylester sodium salt and N-acryloyltris(hydroxymethyl)aminomethane. The invention further discloses a preparation method of the environment-friendly concrete water reducer. The environment-friendly concrete water reducer disclosed by the invention has the advantages that comprehensive performance is excellent, the water reducing effect is more obvious, the mixing amount is smaller, plasticizing performance is more excellent, cost is lower, influence on the environment is smaller, and use is safer and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of concrete additives, in particular to an environmentally friendly concrete water reducer and a preparation method thereof. Background technique [0002] In recent years, my country's basic construction has entered a stage of rapid development, marking an unprecedented scale of major infrastructure projects for urban modernization. The development of these major construction projects is closely related to concrete, and the performance of concrete directly determines the quality of construction projects. pros and cons. Traditional concrete is a kind of building material obtained by using cement as cementitious material, sand and stone as aggregate, mixed with water in a certain proportion, and stirred. In practical engineering applications, this kind of material is often exposed to various relatively The harsh environment leads to a decrease in the service life of concrete. In addition, with the improvement ...

AI Technical Summary

Problems solved by technology

The environmentally friendly concrete water-reducing agent prepared by this preparation method overcomes the more or less high cost, complicated manufacturing process, difficult method to master, low pass rate of the finished product, poor slump resistance, and Low anti-bleeding ability, large conveying resistance, bubbles, poor appearance quality, poor frost resistance, large dosage, poor water-reducing performance, and poor plasticizing effect. It has excellent comprehensive performance and more significant water-reducing effect. Less, better plasticizing performance, lower price, less impact on the environment, and safer and more environmentally friendly to use
