Disposable glass magnesium cement building mould plate and method for preparing same

Abstract

The invention relates to a disposable glass magnesium cement building mould plate, which is characterized in that raw materials, mixed according to mass ratio, includes 13.65% of coal ash, 9.83% of sawdust, 27.29% of magnesium oxide, 21.29% of magnesium chloride, 0.82% of glass fiber cloth, 0.11% of non-woven fabric, 16.37% of reclaimed materials and 10.64% of water. The method includes using aqueous solution of magnesium oxide and magnesium chloride as a main part of slurry, adding the coal ash and sawdust of a certain quantity, using the glass fiber cloth and the non-woven fabric to form a framework with improved tensile and bending resistance, and finally extruding and curing to form the mould plate. The method is simple and convenient, the mould plate produced by the method is high in strength and low in cost, the manufacturing cost of the mould plate is one third of that of traditional bamboo moulds, and the mould plate does not need to be demounted when used in underground engineering so as to be pretty convenient in use.

Description

technical field [0001] The invention belongs to the technical field of building formwork, in particular to a magnesium disposable glass-cement building formwork and a preparation method thereof. Background technique [0002] Building formwork is a temporary structure, which is made according to the design requirements, so that the concrete structure or components can be formed according to the specified position and geometric size, maintain its correct position, and bear the weight of the load. The use of building templates ensures the quality and construction safety of concrete projects, speeds up the construction progress and reduces project costs. [0003] In the past, the more commonly used formwork material was wood, which involved a large amount of construction work and destroyed a large number of forests. According to incomplete statistics, the annual loss of wood has reached hundreds of millions of cubic meters. It is imperative to cancel the timber formwork. There...

[0003] In the past, the more commonly used formwork material was wood, which involved a large amount of construction work and destroyed a large number of forests. According to incomplete statistics, the annual loss of wood has reached hundreds of millions of cubic meters. It is imperative to cancel the timber formwork

Therefore, through research, people gradually use steel formwork to replace traditional wood formwork. These steel formwork are strong and not easily deformed, and the construction is safer and reusable. However, before each use, it needs to be painted on the inner wall to isolate The material on the concrete surface and the inner wall of the formwork needs to be cleaned and reshaped on the inner wall surface of the formwork after each use, which increases the workload, reduces the work efficiency, and increases the construction cost
