Abstract

The invention provides energy-saving composite mortar. The energy-saving composite mortar is prepared from ash calcium powder, silicon powder, sepiolite, gypsum, glass beads, perlite and hydroxy propyl cellulose. The gypsum serving as a main material is lower in cost and higher in strength than cement, so that the mortar is more stable in performance and lower in self weight. The ash calcium powder is used for preventing gypsum from false coagulation and cracking. The perlite can relieve internal force and thermal expansion and cold contraction for the mortar. The sepiolite can resist high temperature and endow the mortar with good fireproof performance. The glass beads play a role in heat preservation. The composite mortar is particularly suitable for laying wooden floors, and has better effects of sound insulation, heat insulation, fire prevention, indoor humidity regulation and the like besides light self weight.

Description

technical field [0001] The invention relates to the technical field of gypsum mortar, in particular to an energy-saving composite mortar, a preparation method of the composite mortar, and an application of the composite mortar in the construction field. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (such as cement, lime paste, clay, etc.) and water, also known as mortar. It can be divided into masonry mortar and plastering mortar. The former is used for masonry and component installation of bricks, stones, blocks, etc.; the latter is used for plastering surfaces such as walls, floors, roofs and beam-column structures. Meet protection and decoration requirements. [0003] According to the composition materials, mortar can also be divided into: ①lime mortar, which is made of lime paste, sand and water according to a certain ratio, and is generally used for masonry and...
