Abstract

The invention belongs to the technical field of the preparation of building materials and particularly relates to a preparation method of high-strength foam concrete. The preparation method comprises:first, preparing sieved powder from raw materials diatomite and volcanic, blending the sieved powder with soybean lecithin for fermentation, preparing bamboo fibers from bamboos, and finally mixing and stirring modified organic matters, the bamboo fibers, polyvinyl alcohol fibers and modified concrete, so as to obtain the high-strength foam concrete. The sieved powder and an ethanol extract are put into a fermentation tank and are sealed for fermentation so as to obtain the modified organic matters, so that the foam concrete prepared from the modified organic matters has hydrophobicity; and by utilizing the bamboos as the raw material, the antibacterial effect of the foam concrete is improved, the service life of the foam concrete can be prolonged, the ductility of a concrete board is improved, the porosity of the prepared foam concrete is increased, and the prepared foam concrete can meet the environmental protection requirement and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a preparation method of high-strength foam concrete. Background technique [0002] Concrete is currently the most widely used man-made building structure material. With the rapid development of modern economy and science and technology, the scope of demand for concrete has been expanded to the construction of ports, highways, bridges, and municipal modernization projects. Its combination with steel bars has created many tall buildings in the world today. In the history of world architecture, the appearance of concrete has greatly improved the load-bearing capacity of human construction facilities. Concrete is widely used in civil engineering because of its easy preparation, easy-to-form components, and outstanding hydraulic properties. [0003] In recent years, driven by building energy-saving policies, building energy-saving technologies and en...
