Embodiment 1

[0015] To make 100 kg of dry-mixed mortar, take 85 kg of aggregate, 2 kg of cellulose ether, 4 kg of latex powder, 1 kg of buffer material, and 8 kg of cement. During production, the aggregate and cement are mixed uniformly to form a base material, and then the uniformly mixed cellulose ether, latex powder, and buffer are added to the base material to make a dry-mixed mortar.

Embodiment 2

[0017] To make 100 kg of dry-mixed mortar, take 30 kg of aggregate, 0.1 kg of cellulose ether, 25 kg of latex powder, 9.9 kg of buffer material, and 35 kg of cement, and prepare dry-mixed mortar according to the method described in Example 1.

Embodiment 3

[0019] Prepare 100 kg of dry-mixed mortar, take 80 kg of aggregate, 1 kg of cellulose ether, 10 kg of latex powder, 5 kg of buffer material, and 4 kg of cement, and prepare dry-mixed mortar according to the method described in Example 1.

Abstract

The invention relates to a composition for preparing dry-mixed mortar. The composition comprises aggregate, cellulose ether, latex powder, cement and a buffer material composed of calcium hydroxide, sodium sulfate and calcium sulfate, wherein with the buffer material, a relatively great quantity of ettringite can be generated after the dry-mixed mortar is mixed with water, the mortar has ideal rigidity, and the mass of the added cement can be reduced.

Description

Technical field [0001] The present invention involves a composition of making dry mortar. Background technique [0002] Dry mixed mortar is used to plaster materials for many fields such as walls, ground, etc., and its application scope is very wide.Traditional raw materials for dry mix mortar usually use ingredients composed of quartz stone slag or limestone residue or white cloud stabs and inorganic adhesives composed of silicate cement, high aluminum cement, gypsum, and water -free gypsum.This kind of dry mixed mortar is a kind of material based on cement and gypsum. According to different building function requirements, it can be mixed with dry powder according to a certain proportion. Although this kind of dry mix can also be used as a wall bondingThe coatings on the wall or wall surface, but because the cement and gypsum are combined with the aggregate, it is very hard, and it is crispy, which is easily damaged by the wall that is bonded or covered on the wall. For this rea...
