Description
Technical Field
The invention relates to the technical field of building materials, relates to foam concrete, and particularly relates to chemically foamed low-density alkali slag foam concrete and a preparation method thereof.
Background
Cement is a common building material used in industry. However, the cement production process consumes a lot of energy and discharges carbon dioxide, and there are data showing: carbon dioxide gas discharged in the process of producing ordinary portland cement accounts for 5% of the global carbon dioxide release amount. This aggravates the greenhouse effect and does not meet the national strategy of low energy and low carbon consumption. The alkali slag cement is a novel cementitious material comprising an alkali metal compound and finely ground water-quenched blast furnace slag as main components, and is an industrial byproduct. The alkali slag cement is named as a cementing material with the greatest development potential in the twenty-first century, and has the advantages of quick setting, quick strength development, excellent fire resistance and chemical corrosion resistance and better freezing resistance than a portland cement system. Compared with portland cement, the energy required for producing the same amount of slag powder is nearly 90% lower, so that the alkali slag concrete is a low-carbon, environment-friendly and low-energy-consumption building material.
At present, because organic heat-insulating materials have the problems of fire hazard, poor durability, easy generation of a large amount of garbage after service and the like, the exit of the building heat-insulating materials represented by polystyrene boards is only a time problem, and under the condition, the research and preparation of inorganic heat-insulating materials will cause the revolution in the field of heat-insulating materials. The alkali slag foam concrete is probably the main force of the inorganic heat-insulating material due to a series of advantages. The existing alkali slag foam concrete is mainly prepared by a chemical foaming method, and the preparation process comprises the steps of uniformly mixing raw materials such as slag, an alkali activator, a foam stabilizer, a foaming agent and the like in a stirring pot; then pouring the mixture into a mould, and utilizing a chemical foaming agent to perform chemical reaction in the slag slurry to generate bubbles so as to expand the slag slurry; after the forming, the light porous heat insulation material is obtained through standard maintenance.
The density of the existing alkali slag foam concrete is generally 300kg/m3In the building structure such as the inner wall, the outer wall, the layer surface, the floor surface, the upright post and the like of the building, the low-density foamed concrete can reduce the dead weight of the building and improve the bearing capacity of the building construction. However, at present, the national concern is lowThe density chemical foaming alkali slag foam concrete is only reported, so how to research and design the chemical foaming low-density alkali slag foam concrete and the preparation method are the problems which need to be solved urgently at present.
