Raw material is cheap, production method is simple, intensity is high, contraction is little, the preparation method of hydrophobic type, fire-retardant heat insulation foamed concrete that the fire-retardant heat insulation performance is good is as follows:
(1) cement, flyash, breeze, water reducer, ether of cellulose, hydrophober, gypsum, anti-crack fiber are mixed makes dry mash.
(2), foaming agent water solution is made foam with air compression foaming machine with the whipping agent dilute with water;
(3) dry mash that step (1) is made adds water and stirs;
(4) foam with step (2) preparation adds mixing and stirring in the cement slurry, makes fire-retardant heat insulation foamed concrete.
The present invention combines flyash, breeze and gypsum, make full use of the microdilatancy characteristic of gypsum aquation and to the vitriol activity excitation effect of flyash and breeze, under the modifying function of components such as high efficiency water reducing agent, ether of cellulose, hydrophober, polypropylene fibre, prepare a kind of high strength, low contraction, hydrophobic type, foamed concrete that thermal and insulating performance is good.Compare with at present traditional foamed concrete, the present invention shows following characteristics:
1. in cement, flyash, breeze, the no water anhydrite quaternary aquation system, the alkali excitation of no water anhydrite and hydrated cementitious has been quickened the secondary hydration reaction of flyash, breeze, has effectively remedied flyash early hydration intensity problem on the low side.
2. the application of high efficiency water reducing agent can improve the following performance of foamed concrete:
1. reduce ratio of water to material, improve the intensity of foamed concrete, remedy the deficiency of its intensity difference;
2. the slurry water consumption reduces, and foamed concrete is little owing to volume that water evaporates is lost in drying process, reduces volumetric shrinkage.
3. improve the cohesion of foamed concrete slurry, it is stable to help foamy, makes foam aperture more even; Reduce the probability that the foam come-up merges, reduce the bleeding passage, help reducing water-intake rate.The application of high efficiency water reducing agent can improve ultimate compression strength, the reduction of foamed concrete and shrink, reduces water-intake rate.
3. adopt ether of cellulose can reduce aperture size, improve the homogeneity in foamed concrete aperture, improve the thermal and insulating performance and the ultimate compression strength of foamed concrete.Ether of cellulose can increase the viscosity of slurry, and it is stable to help foamy, reduces the probability that the vesicle come-up is merged into bulla.Test shows, compares with benchmark foamed concrete, and behind the plain ether of adding of fiber, the foamed concrete aperture size diminishes, and the aperture is more even.The size in aperture is more little, and its thermal and insulating performance is good more, and the network skeleton that the abscess partition forms is firmer.The aperture is even more, and the intensity of foamed concrete is just high more.Thereby the plain ether of adding of fiber helps the raising of foamed concrete intensity and the improvement of thermal and insulating performance.
4. gypsum has certain microdilatancy effect in hydration process, inherent volumetric shrinkage distortion in the compensation water cement-based material hydration process to a certain extent.Simultaneously, flyash self higher fineness and strong micro-aggregate buttressing effect itself have been strengthened the foamed concrete microstructure, have stoped the volumetric shrinkage distortion.On the other hand, the adding of high efficiency water reducing agent has reduced water consumption, has also reduced moulding shrinkage strain.In addition, the cracking resistance component-polypropylene fibre that mixes can effectively stop the crack growth on foamed concrete surface, improve resistance to cleavage, thereby foamed concrete shows good volume stability on one-piece construction.
5. can form firm valence bond with the oh group in the hydrated cementitious product after hydrophober adds and close, be combined in the surface of abscess partition cement matrix hole wall securely.Because hydrophobic organo-functional group towards the outside of hole wall, makes the surface of abscess partition cement matrix hole obtain certain hydrophobic nature, for foamed concrete has brought integral hydrophobic effect preferably.
6. the utilization of industrial waste such as flyash and breeze helps environmental protection and energy saving.
Advantage of the present invention is as follows:
1. foamed concrete intensity height of the present invention, contraction is low, hydrophobic nature good.
2. the thermal and insulating performance excellence can satisfy the different insulation requirement of buildings.
3. preparation technology is simple.
4. make full use of industrial wastes such as flyash, breeze, had the environmental protection effect and the favorable economic benefit of sharp excellence such as useless, energy-conservation.
