High durable underwater non-dispersible concrete flocculant

Abstract

The invention discloses a durable underwater non-dispersible concrete flocculant. A preparation method of the durable underwater non-dispersible concrete flocculant comprises mixing and grinding a polyacrylamide solution, a polydimethyldiallyl ammonium chloride solution, sodium lauryl sulfate and a concrete super plasticizer according to a certain ratio and carrying out detection through the DLT 5117-2000 Underwater Dispersion Concrete Test Regulations. The durable underwater non-dispersible concrete has high curing efficiency, good hardening strength, a high water reduction rate of 20% and good concrete cohesiveness, is easy to stir, has good anti-freezing durability, is conducive to the construction of large-volume concrete, significantly reduces concrete shrinkage, has good product stability, prevents layering in long-term storage and prevents precipitation phenomenon.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and construction materials, and in particular relates to a high-durability underwater non-dispersible concrete flocculant. Background technique [0002] Ordinary concrete is mainly composed of cement, water, sand, stones and admixtures, while the most important thing for underwater non-dispersible concrete is to add an admixture - underwater non-dispersible agent, that is, flocculant. In order to formulate underwater non-dispersible concrete with good performance, it is necessary to make a reasonable selection of its component materials. [0003] At present, developed countries such as Europe and the United States have not formulated regulations and standards for underwater non-dispersible concrete, while Germany, Japan and other countries only have non-dispersant agents and test methods for underwater non-dispersible concrete. [0004] In order to prepare underwater non-dispersible con...
