Mortar for lightweight board of steel framework and preparation method of mortar

Abstract

The invention relates to mortar for a lightweight board of a steel framework and a preparation method of the mortar. The mortar is prepared from components in parts by weight as follows: 100-200 parts of cement, 110-170 parts of perlite, 2.8-5.2 parts of hydroxypropylmethylcellulose, 3.5-9.5 parts of latex powder, 2.8-5.2 parts of short polypropylene fibers, 0.5-1.5 parts of starch ether, 0.5-1.5 parts of calcium formate, 1.4-2.6 parts of a water reducer, 2.8-5.2 parts of lignocellulose, 3.5-9.5 parts of beta-cyclodextrin, 1.4-2.6 parts of sodium carbonate, 1.4-2.6 parts of zeolite-cellulose type water absorbents, 0.5-1.5 parts of a cement foaming agent, 45-75 parts of fly ash and 11-19 parts of gypsum powder. The obtained lightweight board can have multiple properties, and the overall lightweight board is light in weight, high in strength, energy-saving, environment-friendly, long in service life and low in cost, has a smooth surface and has functions of heat preservation, thermal insulation, water resistance and seismic resistance.

Description

technical field [0001] The invention relates to a mortar and a preparation method thereof, in particular to a mortar for steel skeleton light boards and a preparation method thereof. Background technique [0002] In the field of construction, the usual building materials for roof panels, floor panels and wall panels are color steel plates and concrete panels. Among them, color steel plates are light in weight and convenient for construction, but they have short service life, poor fire resistance, and high energy consumption, which is not conducive to energy saving. Reduce consumption. Although concrete slabs have better service life and fire resistance, they are heavy and are generally poured on site. The construction method is single and has a great impact on the environment, which does not conform to the concept of green buildings. In order to overcome the above-mentioned defects, steel skeleton light-weight boards have appeared in the industry, which are mainly supported...

Problems solved by technology

[0002] In the field of construction, the usual building materials for roof panels, floor panels and wall panels are color steel plates and concrete panels. Among them, color steel plates are light in weight and convenient for construction, but they have short service life, poor fire resistance, and high energy consumption, which is not conducive to energy saving. Consumption reduction

Although concrete slabs have better service life and fire resistance, they are heavy and are generally poured on site. The construction method is single and has a great impact on the environment, which does not conform to the concept of green buildings.

In order to overcome the above-mentioned defects, steel skeleton light-weight boards have appeared in the industry, which are mainly supported by light steel skeletons and filled with mortar mixture inside. In order to achieve the dual purpose of light weight and load bearing, the mortar mixture is mostly mixed with cement and perlite However, there is a certain opposition between its load-bearing and thermal insulation, and the product performance has been unsatisfactory, which needs to be improved and improved
