Mine timber substitute material and preparation method thereof
Relating to the technical field of novel building materials, the invention discloses a mine timber substitute material and a preparation method thereof. The mine timber substitute material is mainly composed of a main material, fiber and a composite admixture three components. Specifically, the main material contains 100 parts of magnesium oxide powder, 70-90 parts of a magnesium chloride hexahydrate solution, 10-15 parts of fly ash, 12-15 parts of sawdust, and 5-8 parts of water. The composite admixture includes 1-4 parts of a water reducing agent, 0.2-0.4 part of a retarder, and 2-4 parts of a modifier. The fiber contains 2-4 parts of glass fiber and 25-45 outers of bamboo. According to the invention, magnesium oxychloride cement with high compressive strength and high bending strength is combined with sawdust, fly ash and other solid waste together, the material cost is low, the preparation method is simple and practicable, and has low requirements for production equipment and staff, also the production cycle is short, and the whole process does not produce the three wastes, thus having no influence to the environment and worker health.
