Compound type thickening agent applicable to common wet-mixed mortar

Abstract

The invention relates to a compound type thickening agent applicable to common wet-mixed mortar. The compound type thickening agent applicable to common wet-mixed mortar is characterized by being prepared by mixing a raw materials including 35-54 parts of lithium slags by weight, 5-8 parts of siliceous dust by weight, 4-6 parts of zeolite powder by weight, 0.5-1.4 parts of melamine water reducer by weight, 0.03-0.05 part of polyacrylamide by weight, 1.20-2.80 parts of sodium gluconate by weight, 0.04-0.09 part of sugar by weight and 0.006-0.010 part of triterpenoid saponins by weight. The raw materials are weighted according to the mass proportioning, added in a mixing machine and fully mixed to be uniform, and then the product of the compound type thickening agent can be obtained. The compound type thickening agent can obviously improve the water-retaining property, the cohesiveness and the softness of the common wet-mixed mortar, and enable the common wet-mixed mortar to obtain not only excellent working properties which can meet construction requirements but also better anti-compression strength, cohesive strength and anti-contraction property; and the compound type thickening agent can be applicable to ground mortar, masonry mortar and plastering mortar in the common wet-mixed mortar.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a composite thickener suitable for common wet-mixed mortar. Background technique [0002] Construction mortar is an indispensable main material in construction engineering. It is divided into two categories: ordinary mortar and special mortar. Among them, ordinary mortar includes three types: ground mortar, masonry mortar, and plastering mortar. Special mortar includes waterproof mortar and ceramic tile. Adhesive mortar, interface treatment mortar, self-leveling mortar, grouting mortar, etc., while ordinary mortar accounts for the highest proportion and the largest amount of all construction mortars. [0003] Ordinary mortar can be divided into two categories: dry-mixed mortar and wet-mixed mortar according to different production and construction methods. Dry-mixed mortar, also known as dry-mixed mortar, is made of various dry raw materials (including cementitious materials, f...

AI Technical Summary

Problems solved by technology

[0006] At present, there are some water-retaining thickening materials that improve the performance of ordinary wet-mixed mortar in the domestic construction market, but there are some problems. Some have improved the performance of mortar, but the strength is low; The water retention is poor, and the operability of the mortar is not ideal; some have better performance, and the dosage is extremely low, which leads to high requirements for the accuracy of the metering system, which is not convenient for production and application

There are few types of thickeners with good comprehensive performance and suitable for general production and application available in the market
