Pre-mixed mortar concentrate and its use

Abstract

A composite modifier for premix dry mortar in building engineering consists of latex powder 42-94wt%, cellulose ether 3-27wt%, inducer 0-5.4wt%, starch ether 0-1.2wt%, hydrophobic agent 0-27wt%, inorganic pigment 0-16wt% and organic fibre 0-44wt%. It has excellent thermal-insulating, water-proofing and anti-stain functions and be used for decorative and waterproofing materials, polystyrene foaming board, concrete wall and air-entrained concrete.

Description

technical field [0001] The invention relates to a compound modifier for premixed (dry) mortar widely used in construction engineering, in particular to various types of mortar in current construction engineering, such as preparing masonry mortar, plastering mortar, ground mortar, waterproof mortar, etc. A collection of chemical admixtures, mineral admixtures, fibers, and pigments. Background technique [0002] At present, China's construction is in the ascendant, and housing construction is increasing year by year, reaching 500 million square meters in 2003, mainly public buildings, factories and residential construction, and residential buildings account for the largest proportion. In Shanghai alone, 16 million sq. Therefore, the amount of cementitious materials required for housing construction is huge, but the cementitious materials used in engineering are still traditional materials, which cannot improve the quality of construction. Therefore, the quality of housing co...

Problems solved by technology

And because many premixed (dry) mortar production plants waiting to be put into production lack production technology, especially lack of technology in the selection and use of chemical admixtures

If these factories produce blindly, it will be difficult to guarantee product quality, which will inevitably affect the quality of construction projects and is not conducive to the national policy of sustainable development.
