Abstract

The invention discloses a foam concrete and a preparation method, belonging to the technical field of building materials and construction, comprising the following components of cement, ore powder, fly ash and water, and further comprising a waterproof agent, fibers, an accessory and a foaming agent. The preparation method comprises the following steps of: adding 50-200 parts by weight of the cement, 10-100 parts by weight of the ore powder, 10-150 parts by weight of the fly ash, 60-250 parts by weight of the water, 0-3 parts by weight of the waterproof agent, 0.3-1 part by weight of fiber and 0.1-3 parts by weight of accessory to a container, evenly stirring the components by a stirring machine, adding 6-20 parts by weight of the foaming agent, mixing and stirring the mixture, quickly paving the obtained material on the construction surface for natural smoothing, standing for finishing foaming within 2-30min to obtain the desired strength after 24h, and maintaining to form the formed foam concrete. The invention has high strength, light quantity, low head conductivity coefficient, simple formula, convenient construction and low cost due to the utilization of industrial and mining waste materials, and the invention can partially replace polyvinyl benzene foam boards, extruded sheets and slurry particle insulating boards of a heat insulating system; in addition, the invention is applied to the field construction of a foam concrete heat insulating system of floors and roofs and the production of the foam concrete blocks and heat insulating slabs in a factory by using moulds.

Description

technical field [0001] The invention relates to foam concrete and a preparation method, in particular to high-strength lightweight foam concrete, belonging to the technical field of building materials and construction. Background technique [0002] At present, the construction of the foam concrete insulation system on the floor and roof and the insulation board are prepared into foam by means of mechanical and physical (animal and plant composite) foaming agents, and are transported by mechanical pumping equipment for construction. After the foam is prepared, it is mixed with concrete slurry and used in the floor construction site. The disadvantages are that large-scale mechanical equipment is required, and the construction on the roof of high-rise buildings is difficult, and the foam pore size is uneven, the density is not easy to control, the strength is low, and the cost is high. Contents of the invention [0003] In view of the above problems, the present invention pr...
