Embodiment Construction

[0013] The following are examples of the present invention, and the examples are used to illustrate the present invention, but not to limit the present invention. It is prepared from the following raw materials and methods in weight ratio:

[0014] Fly ash 22 parts Slag 41 parts

[0015] Coal gangue 13 parts Construction waste 13 parts

[0016] Lime 10 parts Gypsum 1.5 parts

[0017] Binder 0.05 parts

[0018] ——The binding agent is sodium silicate or sodium sulfate or carboxymethyl cellulose.

[0019] When the binder is used, only one kind of substance can be used according to the need, and two or more kinds of substances can also be used at the same time.

[0020] The raw materials in the above weight ratio are crushed by physical methods to a particle size of 5mm, and the components are dry-mixed evenly, then stirred with water, put into the mold, vibrated and pressurized, and the product is cured for 12-24 hours, and then dried and wet cured for 5-7 hours. day, let it...

Abstract

The invention relates to a construction material product produced by industrial solid waste and building refuse. The said product is prepared by material at the following weight ratio and method: 18-22 portion of fly ash; 38-46 portion of slag; 8-13 portion ofcoal slack; 8-13 portion of builders rubbish; 5-10 portion of lime; 1.5-6 portion of gypsum; 0.05-0.1 portion of binder. The said raw material is crushed into the particle size of 5mm, and after dry mixing each constituent, adding water and agitating, in-mold vibration and compression are performed to mould. After 12-24 hours of product maintenance and 5-7 days of dry wet curing, natural seasoning is ok. The invention maximizes improving the enviroment to realize the cyclic utilization of waste and regeneration of resource to make the cost lower and the range of building materials larger. The invention can produce building block, mark brick, insulating brick for building wall and also can produce gtound hardening series such as plaza brick, footpath brick; and also can producebearing wall material; and also can produce warming plate, plasterer mortar and the other building materials.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a series of building material products produced from industrial solid waste and construction waste. Background technique [0002] With the development of my country's economic construction and the accelerating pace of urbanization, the continuous growth of solid waste brought about by the expansion of various industrial production scales and the large amount of construction waste brought about by the renewal of urban facilities and the renovation of old cities, not only It takes up space, and seriously pollutes the environment, which brings great harm to the living environment of human beings. Chinese patent application CN02151561 discloses a kind of name "a kind of wall and floor tile produced from construction waste", which does not need to be fired and can make effective use of waste. Compared with the past, when producing building materials such as clay ...
