Abstract

The invention relates to novel energy-saving thermal insulation mortar, which is prepared from the following components in parts by weight: 45 to 53 parts of ordinary Portland cement, 8 to 10 parts of wollastonite, 6 to 8 parts of vermiculite power, 12 to 15 parts of ceramic polished waste residue, 15 to 18 parts of vitrified light hollow microsphere, 8 to 10 parts of fly ash hollow cenosphere, 4 to 6 parts of alumina bubble, 2 to 3 parts of lignin fibre, 2 to 3 parts of polyvinyl alcohol fibre, 1 to 1.5 parts of sucrose fatty acid ester, 4 to 5 parts of hydroxypropyl guar gum, 1 to 1.5 parts of sodium dehydroacetate, 2 to 3 parts of strontium carbonate and 3 to 4 parts of poly carboxylic acid water reducing agent. The novel energy-saving thermal insulation mortar disclosed by the invention is prepared by adopting a special formula and an optimized proportion; waste, such as the ceramic polished waste residues, is utilized, and an excellent comprehensive performance index is achieved; the novel energy-saving thermal insulation mortar is ensured to have an unexpected thermal insulation effect and a crack resistance effect, and is very suitable for various building thermal insulation projects with high requirements.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel energy-saving and thermal insulation mortar and a preparation method thereof. Background technique [0002] Construction mortar is an indispensable and widely used building material in construction engineering. Commonly used building mortar can be divided into masonry mortar, plastering mortar, decorative mortar and special mortar according to function, and can be divided into cement mortar, lime mortar and mixed mortar according to different cementing materials. The mixed mortar includes cement mortar, cement clay mortar and lime clay mortar. Mortar is also sometimes called coarse aggregate-free concrete, and some of the basic theories of concrete apply to mortar as well. However, because the composition and use requirements of mortar are different from those of concrete, it also has its own characteristics, such as the amount of cementitious mat...
