Vynález sa týká úpravy zloženia východiskovéj zmesi pře výrobu pórobetónovýchtvarovaných materiálov na báze elektrárenského popolčeka a dalších přísad.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the modification of the composition of the starting mixture to produce porous concrete shaped materials based on power plant fly ash and other additives.
Medzi najrozšírenejšie stavebné prvky patria tvarované pórobetónové materiály nabáze elektrárenského popolčeka, vápna, připadne cementu a dalších přísad ako je Al-sus-penzia, síran vápenatý a dalšie známe příměsi. Technologie a východisková receptúra jev podstatě ustálená, pórobetónových výrobkov dochádza k poškodeniu hrán, rohov, plochpřipadne vznikajú trhliny. Možno předpokládat, že zlepšením fyz iká lnomechanick.ých vlastností, by bolo možné tieto defekty znížit, nie sú však známe systémy, ktorými by sa to-hoto ciela dosiahlo.Among the most widespread building elements are formed porous concrete materials from power plant fly ash, lime, cement and other additives such as Al-sus-penz, calcium sulfate and other known ingredients. The technology and the initial recipe are basically fixed, porous concrete products are damaged by edges, corners, cracks appear. It can be assumed that by improving physical physical properties, these defects could be reduced, but the systems by which this goal would be achieved are not known.
Podlá tohoto vynálezu zmes na výrobu pórobetónových tvarovaných materiálov na bá-ze elektrárenského popolčeka, vápna připadne cementu a dalších přísad, pozostáva zo 65až 80 hmot. dielov elektrárenského popolčeka, 15 až 20 hmot. dielov vápna, 0,12 až 0,15hmot. dielov Al-pasty a 55 až 70 hmot. dielov vody, 3 až 9 hmot. dielov skelného kalualebo jeho zmesi so síranom vápenatým, pričom úhrnný hmotnostný podiel síranu vápenaté-ho v zmesi je 1 až 3 % hmot. a připadne je vo zmesi 5 až 15 hmot. dielov cementu. Výhodou riešenia podlá vynálezu je, že malou obměnou receptúry sa dosahuje zvýše-nie fyzikálnomechanických vlastností, pričom efektívne sa využívá pre tento účel odpadzo sklářského priemyslu, čím sa súčasne rieši pre sklářsky priemysel ekologický problémlikvidácie skelného kalu s obsahom ionových foriem olova. Výroba pórobetónových tvárníc je technologicky dobré zvládnutá a východiskové su-roviny sú Specifikované závaznými ČSN. Popolček je definovaný v ČSN 22 2067Í cementstruskoportlandský je charakterizovaný ČSN 72 2122. Cement portlandský ČSN 72 2121,pričom sa najčastejšie používá SPC 325 alebo PC 400. Pre Al-pastu platí ČSN 42 0825. ” Vzhladom na to, že suroviny sú definované cestou uvedených ČSN, nie je účelné osobit- ne ich charakterizovat. * Obsah síranu vápenatého v zmesi je potřebné považovat za veličinu, limitovaná a preto sa uvádza ako úhrnné v celej zmesi (súčtové hodnota), z čoho plynie, že zvýše-ný obsah síranu vápenatého v skelnom kale znižuje množstvo přidávaného síranu vápenaté-ho a naopak.According to the present invention, the mixture for the production of aerated concrete materials based on power plant fly ash, lime is cement and other additives consists of 65 to 80 wt. parts of power plant fly ash, 15 to 20 wt. parts of lime, 0.12 to 0.15 wt. parts of Al-paste and 55 to 70 wt. parts of water, 3 to 9 wt. parts of glass calcium or its mixture with calcium sulfate, wherein the total weight fraction of calcium sulfate in the mixture is 1-3 wt%. and optionally 5 to 15 wt. parts of cement. The advantage of the solution according to the invention is that a small variation of the formulation achieves an increase in the physical-mechanical properties, while the waste of the glass industry is effectively used for this purpose, thereby simultaneously solving the ecological problem of the glass sludge disposal with the content of ionic forms of lead. The production of porous concrete molds is technologically good and the starting layers are specified by binding ČSN. The ash is defined in ČSN 22 2067Í cement-cementland is characterized by ČSN 72 2122. Cement Portland ČSN 72 2121, with the most commonly used SPC 325 or PC 400. For Al-paste, ČSN 42 0825 applies. CSN, it is not expedient to characterize them separately. * Calcium sulphate content of the mixture is to be considered as a quantity limited and therefore it is reported as total in the whole mixture (sum value), which means that the increased content of calcium sulphate in the glass sludge reduces the amount of calcium sulphate added and vice versa .
Odpadné sklářské kaly zo sklářského priemyslu odpadajú při brúsení a leštení olov-natého skla kyselinami, převážné zmesami HF a h2S04. Vznikájúci sklářsky kal.sa oddělu-je od leštiacej zmesi filtráciou a premytím a tento sa použije bud priamo alebo po úprave vápnovým mliekom na alkalicky reagujúcu masu s obsahom ihlicovitých čiastočiek pre-stúpených krystalickými doštičkami Ca SO^ · 2 H^O a dalších nerozpuštěných alebo málorozpustných zlúčénín hlavně v přítomnosti Ca(OH)2 bolo zistené aj PbS04, PbCO3,Waste glass sludges from the glass industry do not fall in the sanding and polishing of lead glass with acids, predominantly mixtures of HF and h2S04. The resulting glass sludge is separated from the polishing composition by filtration and washing, and is used either directly or after treatment with lime milk into an alkaline-reacting mass containing needle-like particles discharged with CaSO4 · 2H2O and other undissolved or crystalline platelets. PbSO4, PbCO3, was also found to be low solubility compounds mainly in the presence of Ca (OH) 2,
Pb(OH)2 , Pb3(0H)2(C03)2 vedla K2SiFg, NaSiFg a CaFg. Sklářské kaly podlá zloženiamožno charakterizovat týmito údajmi:Pb (OH) 2, Pb 3 (OH) 2 (CO 3) 2 led to K 2 SiFg, NaSiFg and CaFg. Glass sludges can be characterized by the following data:
Sušina pri 105 °C 60 až 92 hmot. dielov,Dry matter at 105 ° C 60 to 92 wt. parts
CaS04 1 až 30 hmot. dielov,CaSO 4 1 to 30 wt. parts
Ca(0H)2 5 až 25 hmot. dielov,Ca (OH) 2 5 to 25 wt. parts
Si02 30 až 50 hmot. dielov,SiO 2 30 to 50 wt. parts
PbSO^ 1 až 30 hmot. dielov, H20 8 až 40 hmot. dielov. Základná receptúra pri východiskové) zmesi pre výrobu tvarovaných pórobetónovýchmateriálov sa prakticky nemení, avšak prídavkom skelného kalu v rozmedzí 3 až 9 hmot.dielov dochádza k neočekávanému zvýšeniu fyzikálnomechanických vlastností pórobetóno-vých výrobkov, čo teoreticky od8vodňujeme tým, že štruktúra častíc kalov tvořená v pod-statě částicemi ihlicovitého tvaru, vyatužuje pórobetono'· - vú hmotu analogicky ako je to při skloplastoch a v iných vystúžených polymérnych mate-riáloch. Pozitivně sa prejavuje aj přítomnost CaSO^ v skelných kaloch, ke3 znižuje je-ho potřebu ako čistej východiskovéj suroviny. Pri přidávaní skelných kalov je potřebnéPbSO 2 to 1 to 30 wt. parts, H 2 O 8 to 40 wt. parts. The basic formulation of the starting mixture for the production of molded porous concrete materials is practically unchanged, but the addition of glass sludge in the range of 3 to 9 parts by weight results in an unexpected increase in the physical-mechanical properties of the porous concrete products, which theoretically derives from the fact that the sludge particle structure In the case of glass-plastics and other stiffened polymeric materials, the porous concrete mass is similarly reinforced with a needle-like particle. The presence of CaSO4 in the glass sludge is also positively manifested, reducing its need as a pure starting material. It is necessary to add the glass sludge
