Problems solved by technology

[0005] Steel slag is a by-product of the steelmaking process, and steel slag water-washing ball mill mud is the sediment of metal iron extracted by wet water-washing ball milling process, and then the residue after magnetic separation; The rate is about 30%; because steel slag has a certain gelling property, it is difficult to dehydrate the steel slag washing ball mill tailings, and it is easy to harden after drying, which makes it difficult to transport and stack, and seriousl

Example Embodiment

[0042] Example 1: The flame-retardant thermal insulation foamed concrete is prepared according to the mass ratio of various raw materials: 40 parts of cement, 42 parts of fly ash, 18 parts of mineral powder, 0.2 parts of melamine water reducing agent, and 0.03 parts of cellulose ether with a viscosity of 10,000. Parts, 0.2 parts of silane water repellent, 4.8 parts of gypsum, 0.08 parts of polypropylene fiber, 0.20 parts of vegetable protein foaming agent, 0.33 parts of water; its preparation method is as follows: firstly, cement, fly ash, mineral powder, Modified component water reducing agent, cellulose ether, water repellent, gypsum, and polypropylene fiber are mixed uniformly to make a dry powder; dilute the foaming agent with water, and use an air compression foaming machine to make the foaming agent aqueous solution into foam ; Mix the dry powder material with appropriate amount of water. The slurry is required to be uniform, without agglomeration and large particles. Take...

Example Embodiment

[0043] Example 2: The flame-retardant and thermal insulation foamed concrete is prepared according to the mass ratio of various raw materials: 50 parts of cement, 25 parts of fly ash, 25 parts of mineral powder, 0.4 parts of naphthalene-based water reducing agent, and 20,000 viscosity cellulose ether 0.03 parts, 0.4 parts silicone water repellent, 2 parts gypsum, 0.16 parts polypropylene fiber, 0.21 parts animal protein foaming agent, 0.31 parts water; the preparation method is the same as that of Example 1.

Example Embodiment

[0044] Example 3: The flame-retardant thermal insulation foamed concrete is prepared according to the mass ratio of various raw materials: 60 parts of cement, 12 parts of fly ash, 28 parts of mineral powder, 0.3 parts of naphthalene-based water reducing agent, and 20,000 viscosity cellulose ether 0.05 parts, 0.2 parts silicone water-repellent agent, 1.2 parts gypsum, 0.24 parts polypropylene fiber, 0.20 parts animal protein foaming agent, and 0.32 parts water; the preparation method is the same as in Example 1.

Abstract

The invention discloses a steel-slag inflaming-retarding heat-preservation foam concrete. The steel-slag inflaming-retarding heat-preservation foam concrete is prepared from, by mass, 30-60 parts of cement, 30-70 parts of steel-slag water washing dust sludge, 10-40 parts of steel slag composite powder, 0.05-1.0 part of water reducing agent, 0.02-0.2 part of thickening agent, 0.05-1.0 part of water repellent, 1-10 parts of sintered desulfurized ash, 0.06-0.2 part of anti-cracking agent, 0.1-0.4 part of foaming agent and 0.30-0.60 part of water. The steel-slag inflaming-retarding heat-preservation foam concrete has the advantages that the preparing technology is simple, the foam concrete is high in strength, low in shrinkage, good in hydrophobicity, excellent in heat insulation performance and capable of meeting different heat preserving requirements of buildings, industrial waste such as the steel-slag water washing dust sludge, the steel slag composite powder and the sintered desulfurized ash is sufficiently used, and the excellent waste-utilizing and energy-saving environment-protection effect and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to new building materials, and in particular relates to a steel slag flame-retardant and heat-preserving foam concrete and a preparation method thereof. Background technique [0002] In recent years, with the improvement of flame retardant requirements and the enhancement of environmental protection awareness, the non-halogenation, smoke suppression and detoxification of flame retardants have become the frontier topics in the field of current and future flame retardant research; traditional flame retardants are due to their There are serious shortcomings such as large amount of addition, large amount of smoke, and generation of toxic and corrosive gases, which are being replaced by a new generation of environmentally friendly flame retardants. [0003] At the same time, my country's building energy conservation has gradually been promoted to the national strategic level. Multifunctional new building materials that are both flame r...
