High-strength inorganic magnesium cement building template and production method thereof

Abstract

The invention discloses a high-strength inorganic magnesium cement building template and a production method thereof. The building template comprises the following components (in parts by weight): 36-43 parts of magnesium oxide, 40-45 parts of brine, 7-12 parts of coal ash, 4-8 parts of fiber, 0.3-0.5 part of small expanded and vitrified balls, 0.1-0.3 part of phosphoric acid, 0.05-0.15 part of trisodium phosphate, 0.05-0.15 part of NNO and 0.2-0.6 part of ferrous sulphate. 3-6 pieces of fibreglass gridding cloth in matched specification are adopted. The high-strength inorganic magnesium cement building template can be widely applied to concrete moulding of beams, plates and columns in building engineering, concrete moulding of bridges, tunnels and highway stereo hubs in traffic engineering, concrete moulding of dams, water towers and tank bodies in hydraulic and electric engineering, and the like.

Description

technical field [0001] The invention relates to a building template, in particular to a high-strength inorganic magnesium cement building template and a production method thereof. Background technique [0002] With the accelerated development of the construction industry, the amount of cast-in-place concrete structures is increasing, and the use of building formwork is gradually increasing. However, most of the building formwork materials in my country are wood formwork and steel formwork, which also intensifies the resource gap between wood and steel. pressure. [0003] Wooden formwork has limitations such as few service cycles (generally 1-6 times), many joints, poor flatness, and large deformation. In particular, a large amount of wood is consumed, which destroys the environment and ecological balance. direction. [0004] Bamboo plywood has good physical and mechanical properties, but the disadvantages of too strong regional bamboo resources, formaldehyde pollution and p...
