Description
Technical field
The present invention relates to a kind of method and vacuum extractor of making base.
Background technology
The at present mature or making concrete base that developing or the method for unburned adobe have following two kinds of forms: the first adopts low water-cement ratio, and the admixture water reducer is to improve the flowability of batch mixing, the problem that adopts the method to exist the cost of raw material to increase; It two is by external force, make the mixed material " liquefaction " of system concrete base or unburned adobe, for example adopt judder or the closely knit moulding process of vibration compacting, device structure complexity, the component wear that moulding is stirred in the existence of employing the method is big, energy consumption is high, vibrating noise is big, vibration is unreal, influences the problem of concrete base or unburned unfired brick quality.
Summary of the invention
The purpose of this invention is to provide a kind of concrete base or unburned adobe vacuum densification process and used vacuum extractor thereof made, it can solve adopts low water-cement ratio and admixture water reducer to make concrete base or unburned adobe, there is the problem of cost of raw material increase and makes concrete base or unburned adobe by the method for external force, device structure complexity, the component wear that moulding is stirred in existence is big, energy consumption is high, vibrating noise is big, vibration is unreal, influences the problem of concrete base or unburned unfired brick quality.
Method of the present invention is finished like this: the raw material that will make concrete base or unburned adobe is mixed in the mould of packing into behind the thick shape, the vibration mold filling, then the making concrete base in the vacuum chamber of vacuum extractor and the mould of packing into or the thick shape mixed material of unburned adobe are contacted, vacuumize, dewater; The raw material of described making concrete base is made up of according to the proportioning of weight ratio following compositions; Cement: yellow sand: stone: water=1: 1.40～3.60: 2.60～5.30: 0.58～0.66, vacuum are that 700～750mm/Hg, dehydration rate are 26%, and when the ratio of mud reached 0.32, the concrete base was made in the demoulding; The unburned adobe of described making is made up of 30 parts of coal ash, 30 parts of slags, 30 parts of stone nitre, 8～10 parts of cement, 0.2 part of rock sand essence and 30～35 parts of water according to ratio of weight and number; Vacuum is that 450～500mm/Hg, dehydration rate are 28%, and when the ratio of mud reached 0.33, unburned adobe was made in the demoulding; The unburned adobe of perhaps described making is made up of 60 parts of golden Iron Ore Powder, 30 parts of stone flours, 10～15 parts of cement, 0.2 part of rock sand essence, 0.2 part of potassium chloride, 0.2 part of early strength agent and 30～35 parts of water according to ratio of weight and number; Vacuum is that 550～700mm/Hg, dehydration rate are 29%, and when the ratio of mud reached 0.34, unburned adobe was made in the demoulding.
Vacuum extractor of the present invention is made up of vacuum chamber, vacuum-pumping tube, vacuum tank, first tracheae, vavuum pump, second tracheae and water tank; Described vacuum chamber is connected with the air inlet of vacuum tank by vacuum-pumping tube, and the gas outlet of vacuum tank is connected with an end of vavuum pump by first tracheae, and the other end of vavuum pump is connected with water tank by second tracheae.
The present invention has following beneficial effect: one, will pack into making concrete base in the mould or the thick shape mixed material of unburned adobe of the present invention contacts with vacuum chamber, under the effect of vacuum chamber Negative Pressure Difference, mixed material forms negative pressure, and generation pressure differential, superfluous water in the mixed material is constantly extruded, along with the increase in pumpdown time and the increasing of vacuum, the density of mixed material increases thereupon, the concrete base of making or the intensity height of unburned adobe.Two, experimental result shows, the ratio of mud of the mixed material before vacuumizing is 0.50～0.60, after vacuumizing processing, the dehydration rate of mixed material is 25～30%, the remaining ratio of mud is 0.32～0.35, thereby has guaranteed the making concrete base or the needed minimum ratio of mud of unburned adobe (the minimum ratio of mud is about 0.2).Three, simple, the operation easily of method of the present invention, the vacuum extractor that is adopted is simple in structure, and processing cost is low, and concrete base or the unburned unfired brick quality made are good, the yield rate height, and can be suitable for making the concrete base or the unburned adobe of various materials.
