Phosphorus slag powder doped dry powdered anti-crack mortar

Abstract

The invention belongs to the technical field of building materials, and in particular relates to a phosphorus slag powder doped dry powdered anti-crack mortar. The phosphorus slag powder doped dry powdered anti-crack mortar is prepared from ordinary Portland cement, river sand, phosphorus slag powder, slag powder, slag powder activity excitant, cellulose ether, polypropylene fiber, wood fiber, modified attapulgite, a defoaming agent and a water reducing agent. In the invention, the average particle size of the phosphorus slag powder is 30-40 nu m, the specific surface area measured by nitrogen adsorption is 350-400 m<2>/kg, and the mass coefficient K is 1.3-1.4, therefore, the anti-crack mortar has a certain potential volcanic ash activity; the dry powdered anti-crack mortar disclosed by the invention is convenient to operate and easy to control, can be used just after being added with water and stirred on the scene, and has the characteristics of good fluidity, good water retention, high bonding strength, good waterproof and water impermeable effects, strong crack resistance, and the like. A product of the anti-crack mortar disclosed by the invention both can be applied to the bonding and plastering of polystyrene foam boards for external wall insulation and extruded sheets, and also can be applied to occasions such as the repair of easily cracked parts, the refurbishment of ceramic tiles for old walls, and the like. According to the invention, phosphorus slag powder can be effectively used, the added value of phosphorus slag powder can be improved, and social and environmental benefits can be improved; the production cost of the anti-crack mortar can be lowered, and the economic benefit can be improved.

AI Technical Summary

Benefits of technology

This patented technology describes a new type of grout called dried powders (DP) made through combining calcium sulfide flour or other ingredients together. These DP' s have several technical properties such as better flow behavior, higher harden ability compared to traditional hydrauled cements, less pollutant emissions, increased durability against damage caused by weather conditions, reduced manufacture costs, enhanced insulating property without losing moisture content, resistive abilities, and excellent water repellency/water proofings when applied properly. Additionally, this novel composition helps mix well and create stronger structures than existing mixtures.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding ways to improve the quality of building coatings without causing cracks or leaks caused from outside heat isolators installed around buildings. Existing methods involve adding expensive fillers like talc grinding cement and perlite into existing systems, resulting in increased costs associated with these products. Therefore, developing better alternatives would help reduce expenses while maintaining excellent properties of the outer paint layer.
