Example Embodiment

[0019] The present invention relates to a dry-mixed ground mortar that effectively solves ground sanding and peeling, which is composed of the following components in terms of mass percentage:

[0020] Limestone rock machine-made sand 40%-60%

[0021] Yellow sand 20%-30%

[0022] Fly ash 3%-7%

[0023] Cement 15%-21%

[0024] And the remaining additives;

[0025] Wherein, the additive is a modifier and a thickening agent; the modifier is one or more mixtures of cellulose ether, air-entraining agent or water reducing agent; the thickening agent is composed of lithium Mixture of raw materials such as slag, raw gypsum, zeolite powder, lignosulfonate water reducing agent, polyacrylamide, sodium lauryl sulfonate, white sugar, and triterpene saponins. The mass parts of each raw material are: lithium slag 35- 45 parts, 5-8 parts of raw gypsum, 4-6 parts of zeolite powder, 0.5-1.4 parts of lignosulfonate water reducing agent, 0.03-0.05 parts of polyacrylamide, 1.20-2.80 parts of sodium lauryl ...

Abstract

The present invention relates to the technical field of premixing mortar, particularly dry mixed ground mortar for effectively solving dusting and peeling of a ground. The mortar comprises the following components in percentage by mass: 40%-60% of limestone rock machine-made sand, 20%-30% of yellow sand, 3%-7% of coal ash, 15%-21% of cement and the balance of an additive, wherein the additive is a modifying agent and a thickening agent; the modifying agent is one of or a mixture of cellulose ether, an air entraining agent or a water reducing agent.

Description

technical field [0001] The invention relates to the field of ready-mixed mortar, in particular to a dry-mixed ground mortar which effectively solves sanding and peeling of the ground. Background technique [0002] The National Twelfth Five-Year Plan includes my country's urbanization as a development goal, and clearly requires that the national urbanization rate reach 60% by 2020, which means that my country will enter a period of rapid urbanization development. With the vigorous development of various infrastructure constructions, various wear-resistant and crack-resistant floors and self-leveling floors are increasingly used. Traditional dry-mixed mortar generally requires admixtures, but mixing admixtures on site is difficult to ensure product quality, and cannot achieve the goals of soil protection, waste utilization and energy saving. Moreover, the ground mortar mainly has common problems such as ground sanding, ground hollowing, ground cracks and ground peeling. The ...
