preparation example 1

[0042] A kind of stabilizer is prepared by the following method:

[0043] (1) Ingredients: in parts by weight, weigh 40 parts of high-strength shale ceramsite powder, 30 parts of coal gangue powder, and 10 parts of rectified tar;

[0044] (2) uniformly stirring and mixing high-strength shale ceramsite powder and coal gangue powder;

[0045] (3) continue to put into rectifying tar again, fully stir to obtain mixture;

[0046] (4) sintering the mixture in a nitrogen atmosphere at a sintering temperature of 850° C. until the water content reaches below 3%;

[0047] (5) The sintered mixture is pulverized and dried.

Abstract

The invention relates to an additive for ground mortar, a preparation method thereof, and ground mortar. The additive is mainly prepared from the following components in parts by weight: 0.1-0.3 parts of hydroxypropyl methyl cellulose ether and an air-entraining auxiliary, an air-entraining agent. The addition amount of the auxiliary agent is 2% to 8% by weight of the hydroxypropyl methyl cellulose ether; the viscosity of the hydroxypropyl methyl cellulose ether is 8 to 120,000 mPa·s; the preparation method of the additive is stirring, Mixing; the additive is applied to the ground mortar; in the present application, by adding an air-entraining aid to the hydroxypropyl methyl cellulose ether, the air-entraining aid can reduce the viscosity of the hydroxypropyl methyl cellulose ether, and at the same time can improve the The water retention of the ground mortar significantly improves the working performance of the ground mortar; the preparation method of the additive is simple and the molding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of mortar additives, in particular to an additive for ground mortar and a preparation method thereof and ground mortar. Background technique [0002] Dry powder ground mortar is a building mortar made of general Portland cement, sand, mineral admixtures and auxiliary additive materials in a certain proportion, measured and mixed. Compared with traditional mortar, dry powder ground mortar does not need to be mixed with cement and yellow sand on site, and can be used directly by adding water; and the product performance is stable, and its strength and other indicators are better than traditional mortar; the construction is simple, and the mortar does not bleed and is workability. it is good. [0003] The Chinese patent with the application publication number CN106747138A in the existing patent discloses a kind of ground rapid leveling mortar, which is made of the following raw materials by weight, 200-350 par...
