Abstract
The invention discloses a chemical foaming method for preparing a foamed concrete, belonging to the technical field of building heat-insulation materials. The foamed concrete is prepared from the following raw materials in percentage by weight: 20-80wt% of cement, 1-5wt% of ore powder, 5-30wt% of fly ash, 1-6wt% of foaming agent, 10-70wt% of water, 0.2-1.5wt% of modifier, 0.2-1wt% of fiber and 1-8wt% of auxiliary materials. The preparation method of the foamed concrete comprises; firstly pouring water into a container, then adding a certain amount of cement, ore powder, fly ash and auxiliary materials into water, after uniformly stirring with a stirrer, pouring the foaming agent for mixing and stirring, then quickly transferring out of the stirrer, standing to complete foaming within 30 minutes, after 24 hours, reaching the required strength and then curing for 28 days to obtain the formed foamed concrete. The foamed concrete prepared by the method disclosed by the invention has the advantages of good water resistance, low thermal conductivity coefficient, small dry density, high strength, strong durability, simple formula and convenience in construction, and can partially substitute for polystyrene boards, extruded sheets, adhesive powder polystyrene granules and other organic heat-insulation materials in an outer wall heat-insulation system.
Description
Technical field
The present invention relates generally to a kind of chemical blowing process and prepares foamed concrete, and particularly high-strength light foamed concrete belongs to material of construction and technical field of construction.
Background technology
At present, have lightweight, insulation, heat insulation, sound insulation, foamed concrete fire-resistant, durable, water resistance has obtained using widely in building operation.
Using more now is that the physical blowing legal system is equipped with foamed concrete.Specifically: foaming agent water solution is prepared into foam, again foam is joined and contains in the slip that siliceous material, calcareous material (cement, lime), water and various admixture (adopting polycarboxylate dehydragent, hardening accelerator usually) etc. form, through mix that stirring, casting, maintenance form a kind ofly be applicable to that indoor and outdoor bed course, roof heat insulation are heat insulation, non-bearing wall body or porous onsite concrete and goods thereof such as tunnel, foundation ditch filling.The shortcoming of its existence is: the equipment complexity, and bigger in high-rise flooring roof difficulty of construction, and also foam aperture size is uneven, intensity is low, complex process, disposable input height, be unfavorable for that big area promotes.
At present, utilize chemical blowing process to prepare foamed concrete and begin to have obtained application.But there is shortcomings such as poor water resistance, intensity be low, the present invention adopts silylation hydrophober, silicone resin or organosilicon crylic acid latex that it is carried out modification, makes the water tolerance, intensity, fragility etc. of foamed concrete improve.
Summary of the invention
The objective of the invention is defective, provide a kind of chemical blowing process to prepare the method for foamed concrete at above-mentioned prior art.
To achieve these goals, the technical scheme taked of the present invention is:
The component that foamed concrete comprises is: cement, ore powder, flyash, whipping agent, water, properties-correcting agent, fiber and auxiliary material.The weight percent of each component is: cement 20～80wt%, ore powder 1～5wt%, flyash 5～30wt%, whipping agent 1～6wt%, water 10～70wt%, properties-correcting agent 0.2～1.5wt%, fiber 0.2～1wt%, auxiliary material 1～8wt%.
Described cement is silicate cement, aluminosulfate cement or the mixing of the two, and the cement of employing is that strength grade is not less than 42.5 grades general purpose portland cement or aluminosulfate cement; Described mine tailing is one or more the mixing in coarse whiting, SILICA FUME, lime, pearlstone, the red mud; Described flyash is industrial secondary; Described whipping agent is 30% technical grade hydrogen peroxide; Described properties-correcting agent is silylation hydrophober, silicone resin or organosilicon crylic acid latex; Described fiber is a polypropylene fibre; Described auxiliary material is sodium bicarbonate, yellow soda ash or the mixing of the two.
The preparation method of foamed concrete, may further comprise the steps: earlier water 10～70 is poured in the container by weight, then cement 20～80, ore powder 1～5, flyash 5～30, properties-correcting agent 0.2～1.5, fiber 0.2～1, auxiliary material 1～8 are put into water, after stirring with agitator, pour whipping agent 1～6 into and mix stirring, migrate out agitator then rapidly, leaving standstill foamed in 30 minutes finishes, reach intensity after 24 hours, the foamed concrete that maintenance obtained being shaped after 28 days.
The high-performance foam concrete of the present invention's preparation, have lightweight, insulation, water-proof characteristics, has simultaneously high intensity again, can be used as the excellent insulating lagging material and be used for building energy conservation, and because production technique is simple, not only can cast-in-site, also can prefabricated goods, therefore can be widely used in building ground, roofing, body of wall.
