High strength lightweight thermal insulation floor slab and preparation method thereof

Abstract

The invention relates to a high strength lightweight thermal insulation floor slab, which is prepared from the following raw materials in parts by weight: 20-40 parts of flyash ceramsite or volcanic rock ceramsite, 16 parts of cement, 25-35 parts of pumice stone pottery sand, 0.1-3 parts of admixture, 5 parts of organic polymer, 0-4 parts of high strength fibers, 0.25-10 parts of reinforcing steelbars and 25-70 parts of water. A preparation method of the high strength lightweight thermal insulation floor slab comprises the steps of carrying out ball-milling on the raw materials until a certain particle size, mixing the ball-milling products according to a weight ratio, adding a right amount of water, and stirring to obtain a uniform mixture; pouring the slurry, molding, curing, cutting, and drying to obtain the high strength lightweight thermal insulation floor slab. The preparation method is simple in technology and low in energy consumption; the prepared floor slab is high in strength, good in mechanical properties and durability and light in mass, and does not easily drop ash; the organic polymer is combined with the inorganic silicate, so that the obtained floor slab not onlyhas the rigidity of the inorganic silicate, but also has the flexibility of the organic polymer, and the properties such as crack resistance, bending resistance and high durability of the floor slab are accordingly enhanced.

Description

technical field [0001] The invention relates to the field of environment-friendly building materials, in particular to a high-strength light-weight thermal insulation floor slab and a preparation method thereof. Background technique [0002] Fly ash in Inner Mongolia contains a lot of SiO 2 and Al 2 o 3 And other useful resources, if they are comprehensively utilized and prepared into environmentally friendly building materials, it will be able to effectively alleviate the pressure of environmental pollution in our country, and at the same time improve the shortage of resources and other problems. The microscopic morphology of fly ash is a hollow spherical structure, which endows fly ash with physical characteristics such as light weight and low density. The invention makes full use of the physical and chemical properties of fly ash, and at the same time combines organic polymers and inorganic silicates to prepare a high-strength, light-weight thermal insulation with ligh...

Problems solved by technology

[0003] In recent years, with the development of prefabricated green buildings, R&D personnel have made a lot of innovations on components such as beams, columns and nodes, and introduced a series of parts and components suitable for prefabricated buildings. Unsatisfactory, the cost is generally high, and there is no good solution to the compatibility of the high-strength and low-density problems of the floor. Therefore, it is imminent to develop a low-cost, high-strength, and low-density new floor system.
