Description
Oblast technikyField of technology
Vynález sa týká lahkého tepelnoizolačného betonu, pri výrobě ktorého sa spotrebúvajú odpady z iných výrob.The invention relates to a lightweight thermal insulating concrete, in the production of which waste from other productions is consumed.
Súčasnv stav technikyCurrent state of the art
V súčasnosti sa na výrobu lahkých tepelnoizolačných betónov využívájú rožne priemyselné odpady, ako například tehelná drtina, elektrárenský popolček, škvára, spenená troska, dřevný odpad a pod. Podstatná část týchto betónov sa vyrába podlá dosial platných československých noriem.At present, industrial waste, such as brick pulp, power plant fly ash, slag, foamed slag, wood waste and the like, is used for the production of light thermal insulation concrete. A substantial part of these concretes is produced according to the hitherto valid Czechoslovak standards.
Z uvedených priemyselných odpadov možno vyrobil lahký beton s objemovou hmotnostou nad 1100 kg.m a sucimtelom tepelneg vodivosti vyšším ako 0,25 W.m“1.K~1.Light concrete with a bulk density of more than 1100 kg and a thermal conductivity of more than 0.25 Wm -1 .K ~ 1 can be produced from the mentioned industrial wastes.
Pri výrobě potravinářských obalových fólií vznikájú v přírodě tažko rozložitelné odpady, ktoré sú v mnohých prípadoch velmi tažko spalitelné. Niektoré z nich po úpravě znova recyklujú, avšak mnohé nemóžu recykloval, zostávajú na skládkách, kde znečislujú a znehodnocujú životné prostredie.In the production of food packaging films, waste is difficult to decompose in nature, which in many cases is very difficult to burn. Some of them are recycled after treatment, but many cannot be recycled, they remain in landfills where they pollute and degrade the environment.
Podstata vynálezuThe essence of the invention
Uvedený problém rieši lahký tepelnoizolačný beton podlá vynálezu, pozostávajúci z cementu, plniv a vody, ktorého podstatou je, že obsahuje 25 až 35 % hmot, cementu, 20 až 45 % hmot, posekaného alebo inak upraveného fóliového odpadu, 5 až 20 % hmot, doplňkového plniva a zvyšok do 100 % hmot. vody. Doplňkovým plnivem móže byl expandovaný perlit, riečny piesok, alebo ich zmes.This problem is solved by a lightweight thermal insulation concrete according to the invention, consisting of cement, fillers and water, the essence of which is that it contains 25 to 35% by weight, cement, 20 to 45% by weight, chopped or otherwise treated foil waste, 5 to 20% by weight. of additional filler and the remainder up to 100 wt. water. The additional filler may be expanded perlite, river sand, or a mixture thereof.
Z upravených fóliových obalov, expandovaného perlitu (alebo alternativně iných doplňkových plniv, napr. riečneho piesku), cementu a vody sa dajú vyrobil rožne tepelnoizolačné a murovacie tvarovky, vnútorné priečkovky, priečkové dielce a pod. Lahký tepelnoizolačný beton podlá vynálezu sa dá použil ako podkladový a vyrovnávací beton do podláh, ako tepelnoizolačný výplňový beton, alebo ako konštrukčnoizolačný beton.From heat-treated foil packaging, expanded perlite (or alternatively other additional fillers, e.g. river sand), cement and water, it is possible to produce barbecue thermal insulation and masonry fittings, internal partitions, partition parts and the like. The lightweight thermal insulation concrete according to the invention can be used as a base and leveling concrete for floors, as thermal insulation infill concrete or as structural insulation concrete.
Beton podlá vynálezu sa vyrába z dvoj zložkového plniva, pričom prvou zložkou je fóliový odpad upravený do formy aglomerátu a druhou zložkou je expandovaný perlit (alebo iné vhodné doplňkové plnivo, napr. riečny piesok). Spojivom je cement. Všetky zložky sa zmiešajú v miešačke spolu s vodou. Zmes sa ukládá do debnenia alebo do formy, připadne do konštrukcie, kde sa zhutní. Najvhodnější spósob je vibrolisovanie, osvědčilo sa aj dusanie alebo vibrácia. Pri výrobě třeba zásadné dodržal dobu miešania 3 min. Předlženie doby miešania zhoršuje vlastnosti betonu.The concrete according to the invention is produced from a two-component filler, the first component being foil waste formed into an agglomerate and the second component being expanded perlite (or other suitable additional filler, e.g. river sand). The binder is cement. All components are mixed in a mixer together with water. The mixture is placed in a formwork or mold, or in a structure where it is compacted. The most suitable method is vibro-pressing, suffocation or vibration has also proved successful. During production, it was essential to observe a mixing time of 3 minutes. Prolonging the mixing time impairs the properties of the concrete.
Výsledné vlastnosti betonu podlá vynálezu ovplyvňuje spósob zhutňovania zmesi a tvar použitéj formy. Preto před zahájením každéj výroby, pri každéj zmene spósobu zhutňovania alebo tvaru formy, je potřebné ověřit kvalitu výrobkov a potom podlá potřeby regulovat dobu zhutňovania a v krajnom případe aj dávku vody v zmesi. Nedodržanie týchto zásad móže spósobiť, že sa cementový tmel usadzuje v spodněj časti výrobku, pri dne formy alebo debnenia.The resulting properties of the concrete according to the invention are influenced by the method of compaction of the mixture and the shape of the mold used. Therefore, before the start of each production, whenever the method of compaction or the shape of the mold changes, it is necessary to verify the quality of the products and then to regulate the compaction time and, in extreme cases, the dose of water in the mixture. Failure to observe these principles may cause cementitious sealant to settle in the bottom of the product, at the bottom of the mold or formwork.
Hlavnou výhodou lahkého tepelnoizolačného betonu podlá vynálezu je, že na jeho výrobu sa používájú odpady, ktoré znečisťujú životné prostredie, pričom sa z nich vyrobia tepelnoizolačné prvky s výbornými vlastnosťami. Jednotlivé zložky zmesi možno přitom dávkovať v poměrně širokom rozsahu, a to:The main advantage of the lightweight thermal insulation concrete according to the invention is that waste which pollutes the environment is used for its production, and thermal insulation elements with excellent properties are produced from them. The individual components of the mixture can be dosed in a relatively wide range, namely:
upravený fóliový odpad 20,0 až 45,0 % hmot expandovaný perlit 5,0 až 20,0 % hmot cement 25,0 až 45,0 % hmot voda 20,0 až 40,0 % hmottreated foil waste 20.0 to 45.0% by weight expanded perlite 5.0 to 20.0% by weight cement 25.0 to 45.0% by weight water 20.0 to 40.0% by weight
Fóliový posekaný alebo ináč upravený odpad možno použiť aj priamo v stavebných konštrukciách na rózne, predovšetkým tepelnoizolačné zásypy.Foil cut or otherwise treated waste can also be used directly in building structures for various, especially thermal insulation backfills.
Příklady uskutočnenia vynálezuExamples of embodiments of the invention
V nasledovných troch příkladech sa uvádzajú rózne možnosti dávkovania fóliobetónovej zmesi, vhodnéj například pre výrobu murovacich tvaroviek, pričom sa vyrobil vždy 1 m betonovéj zmesi.The following three examples show various dosing options for a foil concrete mix, suitable, for example, for the production of masonry fittings, 1 m in each case producing a concrete mix.
Priemvselná využitelnostIndustrial usability
Základné overené fyzikálně a mechanické vlastnosti sú dokladem toho, že lahký tepelnoizolačný beton podlá vynálezu možno využit v stavebných konštrukciách, predovšetkým na výrobu murovacích a priečkových tvaroviek, ale aj na výrobu dielcov, najma priečkových. Možno ho použit aj na betonáž priamo do debnenia alebo ako tepelnoizolačný beton vo vodorovných konštrukciách například do podláh.The basic verified physical and mechanical properties are proof that the light thermal insulation concrete according to the invention can be used in building constructions, especially for the production of masonry and partition fittings, but also for the production of parts, especially partition ones. It can also be used for concreting directly into the formwork or as thermal insulation concrete in horizontal structures, for example in floors.
