The foam concrete has a large number of closed fine pores, has good heat preservation and heat insulation performance, and can be used as a wall heat preservation and insulation material. The foam concrete can use a large amount of industrial waste materials such as fly ash, slag, alumina red mud and the like as filling materials. Research and development of the material are beneficial to environmental protection and increasingly reduced land resources, and the material accords with national industrial policies, has great significance and broad prospect. At present, the foam concrete with the functions of light weight, heat preservation, heat insulation, sound insulation, fire resistance and water resistance has wide popularization and application prospects in the fields of buildings, traffic, water conservancy, mines and municipal engineering.
However, due to the characteristics of the foam concrete, the foam concrete products sold in the market at present generally have the defects of large shrinkage, water absorption, easy cracking and the like. The shrinkage rate of the common cement concrete is minimum, the shrinkage rate of the cement paste is large, the shrinkage rate of the foam concrete is maximum, the tensile strength of the foam concrete is minimum, and once the shrinkage of the foam concrete is limited, the foam concrete is easy to crack, so that the normal use of the foam concrete is influenced.
In the patent document with publication number CN101497533, a foam concrete and a preparation method thereof are disclosed, the foam concrete comprises a gelled material, a lightweight aggregate, water, an admixture and a foaming agent, and the steps are as follows: (1) pretreatment of raw materials: to prevent hard lumps and hard particles therein from depositing in the foam slurry; (2) weighing the components according to the proportion; (3) preparing and adding a foaming liquid; (4) feeding and stirring: adding water into a stirrer, starting the stirrer, and sequentially adding cement, fly ash, perlite, a waterproof agent, an antifreezing agent, a water reducing agent and fibers; (5) foaming: foaming while stirring the slurry, and firstly sealing a valve and pressurizing by an air compressor; (6) adding foam: after the gelled slurry is prepared, foam is added under the stirring state without stopping the machine; (7) and (3) casting molding: when no floating foam is visible at the pulp surface, the foam pulp preparation is complete. The foam concrete has the functions of light weight, water resistance, fire resistance, heat preservation, frost resistance, crack resistance, earthquake resistance and the like, and is particularly suitable for a heat preservation layer of a cold region engineering and a water plugging and earthquake resistant layer of an underground engineering; the performance of the invention can still be further enhanced.
