Abstract

The invention relates to a light high-strength magnesium oxychloride cement product. The product contains the following components in parts by weight: 315-320 parts of H2O, 1100-1200 parts of MgO, 115-200 parts of industrial bittern MgCl2, 200-300 parts of expanded perlite, 15.5-16.8 parts of polycarboxylate water reducing agent, 7.8-8.5 parts of foaming agent and 15.5-17.0 parts of phosphoric acid. The magnesium oxychloride cement product disclosed by the invention has the following technical effects that the product is light in weight, high in strength and good in heat preservation performance; no hydrate is precipitated on the surface of a test piece; and the salting out phenomenon of a conventional magnesium oxychloride cement product is avoided.

Description

technical field [0001] The invention relates to a modified magnesium oxychloride cement product. Expanded perlite is added to the traditional magnesium oxychloride cement product, which belongs to the field of cement products. Background technique [0002] With the sustained and rapid development of the national economy, the acceleration of urbanization and urban modernization in my country, the increasing requirements for energy conservation and environmental protection, and the continuous increase in labor costs, the traditional construction industry is facing industrial transformation and upgrading, and the promotion of construction industrialization has become the general trend. [0003] Prefabricated lightweight internal partition walls and external wall panels are often used in prefabricated concrete structures. As the enclosure structure of buildings, wall panels are required to have the functions of heat preservation, decoration, strength, and enclosure. Traditional b...
