Abstract

ISOCHAP-YT zijn uitgezeefde cellenbetongranulaten (4/16 mm) voor vloer- of dakisolatie waarmee een Lambda-waarde van 0,14 W/(m.k) (ongebonden) of 0,21 W/(m.K) (cementgebonden) gehaald kan worden. De schadelijke uitloging van sulfaten maakt een toepassing van gebroken cellenbeton in de bodem onmogelijk. Door de droge toepassing kan deze belangrijke hinderpaal voor de recyclage vermeden worden.ISOCHAP-YT are sieved aerated concrete aggregates (4/16 mm) for floor or roof insulation with which a Lambda value of 0.14 W / (m.k) (unbound) or 0.21 W / (m.K) (cement-bound) can be achieved. The harmful leaching of sulphates makes it impossible to use broken aerated concrete in the soil. This important obstacle to recycling can be avoided through dry application.

Description

Het gebruik van gerecycleerd cellenbeton in vloer- of dakisolatie TECHNISCHE BESCHRIJVING InleidingThe use of recycled aerated concrete in floor or roof insulation TECHNICAL DESCRIPTION Introduction

In Vlaanderen wordt het puin afkomstig van sloopwerken voor meer dan 90% gerecycleerd. Naast het puin is er voor de meeste andere fracties van het bouw- en sloopafval ook een valabele recyclagetechniek beschikbaar.In Flanders, the debris from demolition works is recycled for more than 90%. In addition to the rubble, a valid recycling technique is also available for most other fractions of construction and demolition waste.

Gerecycleerd cellenbeton wordt momenteel reeds in chape gebruikt (cfr. octrooiaanvraag BE2009/0672).Recycled aerated concrete is currently already used in screed (cf. patent application BE2009 / 0672).

Cellenbeton is een mengsel van cement, kalk en fijnkorrelig zand. Door de toevoeging van aluminiumpoeder gaat het mengsel rijzen. Hierdoor ontstaat een product met specifieke eigenschappen: licht van gewicht, dragend vermogen, onbrandbaar, hoge isolatiewaarde en een groot accumulerend vermogen. Na opstijving worden de platen in de gewenste formaten gesneden en in een autoclaaf verhard.Aerated concrete is a mixture of cement, lime and fine-grained sand. The mixture will rise due to the addition of aluminum powder. This creates a product with specific properties: light weight, load-bearing capacity, non-flammable, high insulation value and high accumulating capacity. After being stiffened, the plates are cut into the desired sizes and hardened in an autoclave.

Dit product werd meer en meer gebruikt de laatste 20 jaren en zal dus een steeds groter volume gaan uitmaken van het vrijkomende puin. Cellenbeton is echter geen gewenst product in te recycleren puin. De reden hiervoor zijn de beperkte bouwtechnische eigenschappen als funderingsmateriaal maar vooral het feit dat cellenbeton een sterke uitloging van sulfaten naar het grondwater vertoont. Door dit laatste feit zijn alle toepassingen in de bodem zo goed als uitgesloten. Voor gebruik in beton zijn er ook onvoldoende bouwtechnische kwaliteiten toe te schrijven aan het materiaal.This product has been used more and more in the last 20 years and will therefore form an increasing volume of the debris released. However, cellular concrete is not a desirable product in recyclable debris. The reason for this is the limited constructional properties as foundation material, but especially the fact that aerated concrete shows a strong leaching of sulphates to the groundwater. Due to the latter fact, all applications in the soil are virtually excluded. There are also insufficient structural qualities due to the material for use in concrete.

De uitvinding: ISOCHAP-YT®The invention: ISOCHAP-YT®

De uitvinding betreft het gebruik van uitgezeefde cellenbetongranulaten (4/16 mm) in vloer- of dakisolatie. De cellenbetongranulaten (4/16 mm) kunnen los of cementgebonden toegepast worden.The invention relates to the use of screened cellular concrete granulates (4/16 mm) in floor or roof insulation. The aerated concrete aggregates (4/16 mm) can be used loose or cement-bonded.

Uit de laboratoriumproeven, uitgevoerd door het Laboratorium voor akoestiek en thermische fysica van de KULeuven blijkt dat de ongebonden cellenbetongranulaten (4/16 mm) een Lambda-waarde (thermische conductiviteit) van 0,14 W/(m.K) hebben. De cementgebonden cellenbetongranulaten (4/16 mm) hebben een Lambda-waarde (thermische conductiviteit) van 0,21 W/(m.K). Deze toepassing heeft als grote voordeel dat de uitloging van de sulfaten geen probleem vormt, de isloatielagen worden immers steeds afgedekt door vloeren binnen in huis cf waterdichte dakbedekkingen.The laboratory tests carried out by the Laboratory for acoustics and thermal physics at KULeuven show that the unbound cellular concrete aggregates (4/16 mm) have a Lambda value (thermal conductivity) of 0.14 W / (m.K). The cementitious aerated concrete aggregates (4/16 mm) have a Lambda value (thermal conductivity) of 0.21 W / (m.K). This application has the great advantage that the leaching of the sulphates is not a problem, since the insulation layers are always covered by floors inside the house or waterproof roof coverings.

Om gebruikt te kunnen worden dient het cellenbeton d.m.v. een chrusher (betonschaar) verkleind te worden tot een maximale diameter van 200 mm. Vervolgens dient het cellenbeton in een kakenbreker vermalen te worden tot op een kaliber van 0/16 mm. De fractie 4/16 mm kan dan afgezeefd worden voor het gebruik in ISOCHAP-YT®.To be used, the aerated concrete must be obtained by a chrusher (concrete cutter) to be reduced to a maximum diameter of 200 mm. The aerated concrete must then be ground in a jaw crusher to a caliber of 0/16 mm. The 4/16 mm fraction can then be sieved off for use in ISOCHAP-YT®.

Voor de toepassing van de uitgezeefde cellenbetongranulaten (4/16 mm) werd een gebruikscertificaat bekomen bij de OVAM. Het is niet uitgesloten dat dit ook nodig zal zijn voor andere lidstaten. Verder moet het product van een CE-certificaat voorzien worden om te mogen verhandeld worden in de Europese Unie.A certificate of use has been obtained from OVAM for the use of the screened cellular concrete granulates (4/16 mm). It is not excluded that this will also be necessary for other Member States. Furthermore, the product must be provided with a CE certificate in order to be traded in the European Union.

CONCLUSIE De voorgestelde uitvinding speelt in op de vraag naar duurzame isolatiematerialen in de bouw én opent een belangrijke afzetmarkt voor gerecycleerd cellenbeton . Op deze wijze is een economische relevantie gekoppeld aan een maatschappelijke relevantie. Het milieu kan door de recyclage immers ontlast worden door het verminderen van het delven van primaire grondstoffen. Afhankelijk van de toepassing kan met de uitgezeefde cellenbetongranulaten (4/16 mm) een Lambda-waarde van 0,14 W/(m.K) (ongebonden) of 0,21 W/(m.k.) (cementgebonden) gehaald worden. Om gebruikt te kunnen worden dient het cellenbeton d.m.v. een chrusher (betonschaar) verkleind te worden tot een maximale diameter van 200 mm. Vervolgens dient het cellenbeton in een kakenbreker vermalen te worden tot op een kaliber van 0/16 mm. De fractie 4/16 mm kan dan afgezeefd worden voor het gebruik in ISOCHAP-YT®.CONCLUSION The proposed invention responds to the demand for sustainable insulation materials in construction and opens up an important market for recycled cellular concrete. In this way an economic relevance is linked to a social relevance. After all, the environment can be relieved by recycling by reducing the extraction of primary raw materials. Depending on the application, the screened aerated concrete aggregates (4/16 mm) can achieve a Lambda value of 0.14 W / (m.K) (unbound) or 0.21 W / (m.k.) (Cement-bound). To be used, the aerated concrete must be obtained by a chrusher (concrete cutter) to be reduced to a maximum diameter of 200 mm. The aerated concrete must then be ground in a jaw crusher to a caliber of 0/16 mm. The 4/16 mm fraction can then be sieved off for use in ISOCHAP-YT®.
