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 formedfoam 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 miningwaste 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
The present invention relates to foamed concrete and preparation method, especially high-strength light foamed concrete belongs to material of construction and technical field of construction.
Background technology
At present; The construction of the foamed concrete heat-insulation system of flooring, roof and heat preservation plate material all adopt mechanical-physical (animal and plant are compound) whipping agent mode to be prepared into foam; Adopting mechanical pumping equipment to carry constructs; After the foam preparation that foaming is good is good, mix stirring again with the concrete slurry, be used for the floor working-yard.The shortcoming that exists is that need used heavy mechanical equipment, and are bigger in high-rise flooring roof difficulty of construction, and the foam aperture size is uneven, density is wayward, intensity is low, cost is high.
Summary of the invention
To the problems referred to above, the present invention provides a kind of foamed concrete and method that adopts the chemicalfoaming preparation.
The technical solution adopted for the present invention to solve the technical problems is:
Foamed concrete, the component that comprises is: cement, ore powder, flyash and water also comprise following component: water-resisting agent, fiber, auxiliary material and whipping agent; The parts by weight of each component are: cement 50-200, ore powder are 10-100, flyash 10-150, water 60-250, water-resisting agent 0-3, fiber 0.3-1, auxiliary material 0.1-3, whipping agent 6-20.
The preparation method of foamed concrete may further comprise the steps: by weight with cement 50-200, and ore powder 10-100, flyash 10-150; Water 60-250, water-resisting agent 0-3, fiber 0.3-1, auxiliary material 0.1-3 puts into container; After stirring with whisking appliance, pour whipping agent 6-20 into and mix and stir, pave rapidly, treat the nature levelling to construction surface; Foaming in 2-30 minute after leaving standstill finishes, and reaches intensity after 24 hours, after maintenance, forms the foamed concrete that is shaped.
The invention has the beneficial effects as follows that intensity is high, light weight, thermal conductivity is low, and prescription is simple, easy construction; Utilize the industrial and mineral waste material, reduce cost, can partly replace polystyrene foam plate, extruded sheet and heat insulation system pulp particle warming plate.Be applicable in foamed concrete heat-insulation system construction and the factory of on-the-spot flooring underground heat, roof with die production foamed concrete piece and heat preservation plate material.
