Multipurpose convenient cement

Abstract

The invention relates to multipurpose convenient cement. The multipurpose convenient cement is composed of the following raw materials in parts by weight: 20-50 parts of cement, 41.9-66.65 parts of dry sand, 2-10 parts of calcium carbonate, 0.1-0.5 part of cellulose ether, 0.5-4.5 parts of redispersible latex powder, 0.05-0.1 part of an anti-skid auxiliary agent, and 0.1-0.5 part of starch ether. The product is prepared by screening natural sand, washing with water and sending to a baking rotary furnace to baking the natural sand to form dry sand, then pouring the above raw materials into an electric dry mixer according to the above ratios, stirring, after 10 min, conveying the uniformly-stirred raw materials into a material storage tank and packaging by a packager. The cement is environment-friendly, and has the fluidity, the volume density, the water retention property, the water-adsorption gas content, the plastic cracking property, the dry shrinkage, the compressive strength, the rupture strength, the adhesive strength, the flexibility, the impact resistance and the like all substantially better than those of common cement dry-mixed products.

Description

technical field

[0001] The invention relates to a building material, in particular to a multi-purpose convenient cement. Background technique

[0002] Against the background of accelerated domestic urbanization and the gradual maturity of international contracting business, my country's construction industry has broad prospects for development. The raw materials for construction, such as cement and sand, also developed accordingly. In modern society, with the development of cities and the improvement of people's living conditions, residential buildings are gradually developing to high-rise buildings. If you use the previous cement mortar, because of its poor water retention and viscosity, you need a thick layer of mortar and a large load, so you need a new type of cement material. Keep up with architectural development needs. Now the mortar used in the construction industry is made by mixing cement, sand and water on site. This kind of mortar has the following defects. One...

Embodiment 1

[0020] In terms of 100kg product, natural fine sand is selected and sieved. After washing, it is transported to a drying furnace by a conveyor belt for drying. After it comes out, it is dry sand. Then add 30kg of cement, 66.65kg of dry sand, 2.5kg of calcium carbonate, 0.2kg of cellulose ether, 0.5kg of redispersible latex powder, 0.05kg of anti-slip additive, and 0.1kg of starch ether. Pour it into a dry mixer for stirring, and after stirring for 10 minutes, put it into a storage tank for storage, and then fill it with an automatic filling machine to produce the above-mentioned multi-purpose convenient cement.

Embodiment 2

[0022] In terms of 100kg product, natural fine sand is selected and sieved. After washing, it is transported to a drying furnace by a conveyor belt for drying. After it comes out, it is dry sand. Then add 40kg of cement, 53.27kg of dry sand, 5kg of calcium carbonate, 0.35kg of cellulose ether, 1.0kg of redispersible latex powder, 0.08kg of anti-slip additive, and 0.3kg of starch ether. Pour it into a dry mixer for stirring, and after stirring for 10 minutes, put it into a storage tank for storage, and then fill it with an automatic filling machine to produce the above-mentioned multi-purpose convenient cement.

Embodiment 3

[0024] In terms of 100kg product, natural fine sand is selected and sieved. After washing, it is transported to a drying furnace by a conveyor belt for drying. After it comes out, it is dry sand. Then 50kg of cement, 41.9kg of dry sand, 5kg of calcium carbonate, 0.5kg of cellulose ether, 2.0kg of redispersible latex powder, 0.1kg of anti-slip additive, and 0.5kg of starch ether. Pour it into a dry mixer for stirring, and after stirring for 10 minutes, put it into a storage tank for storage, and then fill it with an automatic filling machine to produce the above-mentioned multi-purpose convenient cement.

[0025] Usage and dosage of multi-purpose convenient cement:

[0026] 1. Mix this product with clean water (ratio: cement to water ratio is 4:1) and stir evenly, stand still for 5-10 minutes, and stir again. Add water if too thick.

[0027] 2. The reference dosage varies according to the specific conditions of the project. For example, the amount of pasting tiles: use a 3×3...
