Problems solved by technology

[0004] The existing cement mortar dry powder is usually made by mixing cement, fly ash, yellow sand and other raw materials. The cement mortar mixture made after adding water and mixing has poor water retention, and the cement mortar mixture is easy to form water-permeable channels inside. Affect the compactness of the cement mortar mixture, resulting in a reduction in the strength and durability of the cement mortar

Abstract

The invention relates to cement mortar dry powder which comprises the following components in percentage by mass: 35-45% of yellow sand, 20-25% of fly ash, 15-20% of cement, 5-15% of mineral powder, 5-10% of stone powder, 2-4% of polyurethane foam particles, 1-2% of a thickening powder, 0.1-0.3% of a waterproof agent, 0.2-0.3% of fatty alcohol polyvinyl sodium sulfonate, 0.15-0.25% of sodium abietate, 0.1-0.2% of silicone amide and 0.01-0.02% of calcium formate. The thickening powder comprises the following components in parts by weight: 380-420 kg / t of bentonite, 30-45 kg / t of rubber powder,20-30 kg / t of hydroxypropyl methylcellulose, 15-20 kg / t of sodium polyacrylate and 2-5 kg / t of a water reducer. The cement mortar dry powder has the effect of improving the physical property of cementmortar mixing.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a dry cement mortar powder. Background technique [0002] Cement mortar dry powder, also known as dry powder mortar and dry mix powder, refers to a granular or powdery material that is physically mixed in a certain proportion of aggregates, inorganic cementitious materials and additives that have been dried and screened. Dry powder is usually transported to the construction site in bags or bulk for use, and can be used directly after mixing with water. Cement mortar dry powder plays the role of bonding, lining, protection and decoration with its thin layer, and is extremely widely used in construction and decoration engineering. [0003] Wall plastering refers to the surface layer engineering that mixes dry cement mortar powder and clear water according to a certain proportion to form cement mortar and then evenly applies it on the wall surface. Plastering of indoor ...
