High-standard concrete state regulator and preparation method thereof

Abstract

The invention provides a high-standard concrete state regulator and a preparation method thereof. The concrete state regulator is prepared from the following components and raw materials in parts by mass: 15-20 parts of acrylamide monomers, 1.2-2.0 parts of an acrylic monomer, 0.8-1.1 parts of a hydrophobic monomer, 2.0-4.0 parts of a polyether monomer, 0.02-0.05 part of an initiator, 8.0-8.5 parts of lye and 1300-1800 parts of deionized water, wherein the acrylamide monomer is one or two kinds of acrylamide and 2-acrylamido-2-methylpropanesulfonic acid; the acrylic monomer is one kind of acrylic acid, methacrylic acid, fumaric acid and maleic anhydride; the hydrophobic monomer is vinyl acetate; the polyether monomer is methyl allyl polyethenoxy ether; the initiator is a redox system. Theinvention also provides the preparation method. The high-standard concrete state regulator provided by the invention has the beneficial effects of good cohesive performance in high-standard concrete,moderate viscosity, good flow rate, no hardening, easy construction, good performance, and simple preparation process.

Description

technical field [0001] The invention relates to a concrete state modifier, in particular to a high-standard concrete state regulator. The invention also relates to a preparation method of the high-standard concrete state regulator. Background technique [0002] Currently, the commonly used concrete state regulators on the market are mainly cellulose, dextrin, and polymer solutions. Among them, cellulose and dextrin reduce the water-reducing rate of the water-reducing agent more, and their solubility is poor. After standing still, they often sink to the bottom of the container and form a gel. Polymer solution is a uniform and stable solution, which can show good state modification performance in low-standard concrete, but in high-standard concrete, it will cause the viscosity of the concrete to increase sharply, the flow rate of the slurry is slow, and the state becomes hard. Increased the construction difficulty of high standard concrete. [0003] The inventor retrieved t...
