Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an i...

Abstract

The invention discloses foamed concrete and a preparation method thereof. The foamed concrete comprises the following raw materials in parts by weight: 160-200 parts of cement, 60-140 parts of ore powder, 60-130 parts of fly ash, 120-210 parts of water, 80-140 parts of a foam material, 12-25 parts of a binder, 10-20 parts of a foaming agent, 10-20 parts of a dispersant and 60-90 parts of coated wollastonite powder, wherein the coated wollastonite powder is prepared by the following steps: firstly, performing ball mill dispersion treatment on a raw material, namely wollastonite powder, with alcohol for 4-6 hours, drying obtained slurry, and sintering the dried slurry for 2-3 hours at 420-480 DEG C. As gaps in the surface of the foamed concrete is bonded by using a waterproof adhesive, heatconduction of the foamed concrete is prevented, then the heat conductivity of the foamed concrete is improved, the flame retardancy and compressive strength can be greatly improved, the shock resistance, the sound insulation and the weather resistance of a finished product, namely a foamed concrete product, can be improved to a certain extent, and the reliability and the practicability of the product can be improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a foam concrete and a preparation method thereof. Background technique [0002] In recent years, the domestic requirements for energy conservation, environmental protection and environmental protection have been continuously improved. The energy-saving work in residential construction has been deepened, and energy-saving standards have been continuously improved. Many new energy-saving technologies and materials have been introduced and developed. They are vigorously promoted and used in residential buildings. A new type of energy-saving material that is waste-recycling, environmentally friendly, energy-saving, fire-proof, and cheap. It has a special porous structure and excellent thermal insulation performance. The production of foam concrete can utilize a large amount of industrial waste such as fly ash, slag, and stone powder, reducing waste products. The discharge can effect...
