Description

A kind of flyash in great mixed amount ceramsite foam concrete and preparation method thereof
Technical field
The invention belongs to building material technical field, be specifically related to a kind of flyash in great mixed amount ceramsite foam concrete and preparation method thereof.
Background technology
At present, the common wall thermal insulating heat-barrier material of China mainly includes machine class heat preserving and insulating material and the big class of mineral-type heat preserving and insulating material two, and wherein foam concrete is a kind of typical mineral-type heat preserving and insulating material. The main application fields of foam concrete is that building heat preservation is heat insulation, accounts for about the 80% of its total output. With market common are machine class insulation material such as polystyrene foam plate, phenolic foam board is compared, and foam concrete has intensity height, long service life, the advantages such as fire protecting performance is good. Itself there is the shortcoming that unit weight is of a relatively high in existing foam concrete, if reducing unit weight by improving the method for foam volume, then the foam concrete volume poor stability produced, intensity is low; And existing foam concrete is typically all employing cement and flyash as powder, then pass through addition water, foaming agent carries out what foaming was formed, for the workability making slurry have, improve the intensity of foam concrete simultaneously, generally adding relatively more cement, material cost is higher, additionally due to ordinary portland cement is long for setting time, the mould turnaround time can extend, and also results in the rising of production cost. The Chinese patent of application number 201210249734.4 discloses a kind of insulating foam preparation method of concrete applying andesite stone powder, defect higher in order to solve cement cost in this patent, adopt in powder, add andesite stone powder, although reducing the consumption of cement to a certain extent, but owing to andesite is a kind of natural crystal, need to be broken into stone powder could use, and the trade waste that flyash is the factories such as power plant, itself it is powdered granule, uses the cost of andesite to compare its cost of flyash still higher. The density ratio of andesite is higher, and its proportion is relatively big, can not solve the defect that the unit weight of existing foam concrete itself is of a relatively high.
Of a relatively high in order to solve foam concrete unit weight, the shortcoming of volume stability difference, also there is partial monopoly to adopt and add haydite in the feed, such as in the patent of invention that the patent No. is 201010294645.2 of China's application, disclosing a kind of Novel foam concrete preparation technology, this concrete uses proportioning to be cement: haydite: flyash 4:3:3 or cement: haydite: flyash 4:2:4 prepares dry density 700-1200kg/m3Foam concrete.In order to ensure concrete intensity workability, in this patent, cement makes the consumption consumption more than flyash, and the consumption of cement is relatively larger, and the problem that its cost unresolved is high. haydite accounts for the 20%-30% of powder gross mass, although reduce concrete proportion to a certain extent, but its unit weight is still higher, and the foam concrete mechanical strength for preparing of this formula and volume stability are all poor, application number be 201310047960.9 Chinese patent disclose a kind of steel tube foam concrete combination column and construction method, this patent further discloses a kind of foam concrete formula, its proportioning is cement 28%-32%, haydite 35%-40%, flyash 10%-12%, silicon ash 10%-15%, Gypsum Fibrosum 3%-5% prepares foam concrete, in whole proportioning, flyash accounts for the 18%-24% of Binder Materials gross mass, haydite accounts for the 35%-40% of powder gross mass, this patent equally exists cement and makes the defect of large usage quantity, simultaneously in order to provide raising concrete strength and durability to the addition of silicon ash, gypsum raw material, it is higher that silicon ash compares its cost of flyash with Gypsum Fibrosum.
In addition, for mixing the foam concrete of flyash in the preparation technology of existing foam concrete, for ensureing early strength, it is common practice to it is steam-cured, make technique more loaded down with trivial details; And present stage ceramsite foam concrete moulding process is slurry for the stirring that first Binder Materials added water; foam concrete slurry is mixed again with foams mix Cheng Xin; last and haydite is mixed into ceramsite foam concrete; in the mixed process of haydite, foam crushes in a large number, is difficult to prepare the ceramsite foam concrete of ultra-low-density.
