Mortar partner and its use

Abstract

A composite modifier for mortar in building engineering consists of lime mountain flour 50-85wt%, latex powder 8-30wt%, cellulose ether 0.5-14wt%, inducer 0-0.3wt%, starch ether 0-0.2wt%, hydrophobic agent 0-5wt%, inorganic pigment 0-3wt% and organic fibre 0-18wt%. 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 present invention relates to a compound modifier for mortar widely used in construction engineering, and specifically relates to various types of mortar in current construction engineering, such as chemical admixtures for preparing masonry mortar, plastering mortar, ground mortar, waterproof mortar, etc. , Mineral admixtures, fibers or pigments, etc. aggregates. 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. Surface phenomena such as de...

Problems solved by technology

[0005] There are many types of admixtures, and their performance is closely related to the dosage. Improper proportioning or too large or too small dosage will cause adverse consequences in quality or economy.

And the construction site lacks professionals, it is impossible to prepare these chemical admixtures on the construction site
