The forming process of cinder foamed concrete of the present invention building block can be divided into two stages.Fs is the preparation of physical blowing stage and expanding foam solution, and the general concentration of whipping agent is bigger, can not directly join foaming machine and use, and all should be made into the dilution expanding foam solution earlier before use.The proportioning of diluent is made into the dilution expanding foam solution with 30 times ratio of whipping agent weight part to water.The concrete practice is: X 2073 whipping agent, SEPIGEL 305 suds-stabilizing agent and water are mixed process expanding foam solution and make expanding foam solution pure through filtering; It is subsequent use to be stored in the interior sealing of stock chest jar; Add or adopt full-automatic pumping to advance in the foaming machine with artificial; Generally 20min joins expanding foam solution in the foaming machine before foaming machine start, and making in the air admission foaming agent solution foams expanding foam solution with the high-pressure air foaming machine processes foam.The froth quality requirement, the foam that the general requirement foaming machine is made, bubble diameter is little, foam is even, product bubble amount is big, and bubble diameter is between 0.5mm～1mm.Be applicable to and produce 200kg/m
3The foamed concrete of above middle-high density and specification of quality.
Subordinate phase is the stage that foam forms the foamed concrete air vent wall, and the foam made from foaming machine finally becomes the foamed concrete pore, is changed to the gas, liquid, solid interface by gas, liquid, interface.Foam was the gas-liquid two-phase system originally, surrounded gas by liquid film.And the gelling material slurry is the granuloplastic liquid of water and gelling material, solid two-phase system.Foam is sneaked into the gelling material slurry, and the two just becomes the gas, liquid, solid three-phase system, and promptly slip is by bubble, water, solid particulate three phase composites.This variation changes the liquid film of bubble thereupon, and bubble becomes the liquid-solid composite film by simple liquid film, is sticking solid particulates such as cement slurry on the rete of bubble; Air bubble liquid-membrane originally is very thin, has only several nanometers, stick solid particulate after; Make liquid film by thin thickening; And bubble is after getting into gelling material slurry such as cement, and stability increases, for Gu Pao has created good condition.
This stage is from beginning behind the casting to the slurry initial set; Be that the quiet of gelling material stops the initial set stage; The gelling particle that foam begins to be attached on the bubble chamber film slowly generates gum material; Produce certain intensity, the liquid film physical strength that existing foam is initial, the adhesion layer intensity that also has gum material to produce.Just begun and the initial stage in hydration, the foam solution film strength still plays a part leading, and in later stage during near initial set, the intensity that gelling produces then accounts for leading role.The length in this stage, the presetting period of depending on gelling material is its rate of set, also depends on the type of gelling material hydrated product in addition.The gelling material presetting period is short more, and the gelling of hydrate is strong more, and foam is just stable more.Simultaneously, the variation of matter will take place in foam, and the foamy rete will change gas, liquid/solid interface into by liquid, gas, solid three phase boundary, and aquation begins to accelerate, and a large amount of hydration heat make the moisture evaporation of bubble film.Simultaneously, the aquation of gelling material needs a large amount of water, and the water between bubble film and bubble is by aquation consumption, and this just makes foamy liquid film attenuate gradually, last completely dissolve.Originally attached to the water on the bubble chamber film in the process of moisture film attenuate, replace moisture film gradually, formed a gelatinuous layer that surrounds gas, when bubble film disappears, the gelatinuous layer complete closed air, the formation air vent wall.So foam has been accomplished the whole process that changes to pore, makes foam become pore, is fixed in the concrete by gum material, makes original foamy liquid film, has formed the concrete air vent wall.
At normal temperatures and pressures, slip is expanded, material aquations such as cement and quicklime are condensed, form the very low vesicular structure base substrate of a kind of intensity; Calcareous material and siliceous material in the base substrate are reacted; In slip, formed numerous trickle pores; The volume of slip is expanded gradually; Moisture in the slip is owing to participate in reaction and become combination water and reduce gradually, and hydrated product concentration in solution increases gradually and reaches capacity state and separate out small crystal.The liquid of crystallite and cohesion has become the state of aggregation that loses flowability gradually, and it is lower but can bear the base substrate of the quality of self to have formed intensity.This mainly is that the hydro-thermal of calcareous material and siliceous material is synthetic, the hydrated product of generation again further with cinder powder and waste polystyrene foam powder generation hydro-thermal reaction, generate and hold in the palm vigorous mullite and low calcium hydrated calcium silicate.In order to make the building block of cinder foamed concrete have good performance, must make material internal have the vigorous mullite of more holder to form.Ask vigorous mullite to be a kind of plate crystal body, higher intensity is arranged, and contraction ratio is less.Low calcium hydrated calcium silicate is a kind of noncrystalline product of curling shape, higher intensity is also arranged, but dry shrinkage is bigger.Begin to be reacted to the process that loses flowability and have certain structural strength from slip, be called curing.Along with the completion of solidification process, the vesicular structure in the base substrate basically forms, and hydration reaction is proceeded simultaneously, and hole wall structure is fine and close day by day, and strengthens gradually, and blank strength is increased.
Utilize calcium sulfate in slip, to regulate the trithiophenol salt type aquation calcium sulphoaluminate that has originally generated and resolve into anhydrous calciumsulphate and aquation aluminate, residue aquation aluminate that contains in this part aquation aluminate and the slip and the SiO in the siliceous material
2Effect generates the sub-stone of mirabilitum crystallina pomegranate.Make in the cinder powder and contain Al
2O
3With SiO
2Effect generates the sub-stone of mirabilitum crystallina pomegranate.Quicklime is met water and is cleared up into Ca (OH)
2Under field conditions (factors), Ca (OH)
2With the SiO in the siliceous material
2React, generate high alkalinity aquation Calucium Silicate powder, these hydrated products again with unreacted SiO still
2Continue reaction and generate low buck Calucium Silicate powder, generate low calcium hydrated calcium silicate and Tuo Bo mullite at last.
Main resultant in the cinder foamed concrete block structure all is vigorous mullite of holder and low calcium hydrated calcium silicate; Next is the sub-stone of mirabilitum crystallina pomegranate; Its internal structure is to be kernel with unreacted hard siliceous material; Periphery is wrapped in a large amount of hydro-thermal reaction resultants-tabular vigorous mullite of holder and low calcium hydrated calcium silicate, and forms fine and close porous crystalline body, thereby makes the building block of cinder foamed concrete have enough intensity.
The cinder foamed concrete building block of producing according to the present invention technology, through the relevant building materials quality detection department check of national regulation, each item technical indicator all reaches the construction material standard-required of national regulation.
