Abstract
CHAP-YTR is een chapemengsel waarin 50-100% gerecycleerd cellenbeton (0/3), afkomstig van sloopwerken, wordt gebruikt tesamen 50-0% rijnzand (0/3). Afhankelijk van de toegevoegde hoeveelheid cement kunnen druksterktes gehaald worden van 3 tot 8 Mpa. 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.CHAP-YTR is a screed mix in which 50-100% recycled aerated concrete (0/3), from demolition works, is used together with 50-0% rhine sand (0/3). Depending on the amount of cement added, compressive strengths can be achieved from 3 to 8 Mpa. The harmful leaching of sulphates makes it impossible to use broken aerated concrete in the soil. The dry application avoids this important obstacle to recycling.
Description
TECHNISCHE BESCHRIJVING InleidingTECHNICAL 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 rubble 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.
Enkel voor cellenbeton ontbreekt dit nog in Vlaanderen. In Nederland maakt men wel gewag van de recyclage hiervan maar zeer waarschijnlijk voor hergebruik in nieuw cellenbeton of gipsproducten.Only for aerated concrete is this still missing in Flanders. In the Netherlands the recycling of this is mentioned, but most likely for reuse in new aerated concrete or plaster products.
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: CHAP-YT®The invention: CHAP-YT®
De uitvinding betreft het gebruik van vermalen cellenbeton in chape of dekvloer. Dit is de laag die in principe geplaatst wordt boven de druklaag die op de welfsels ligt of bovenop de betonplaat. Deze laag bestaat meestal uit een mengsel van cement en zand (chapelaag).The invention relates to the use of crushed aerated concrete in screed or screed. This is the layer that is in principle placed above the pressure layer that lies on the cladding or on top of the concrete slab. This layer usually consists of a mixture of cement and sand (chapel layer).
Uit de bouwtechnische proeven die we zelf hebben uitgevoerd blijkt dat een mengsel van zand en vermalen cellenbeton geschikt is om een kwalitatief goede chape te maken. Deze toepassing heeft als grote voordeel dat de uitloging van de sulfaten geen probleem vormt, chape is immers steeds toegepast in een volledig droge omgeving afgesloten van het grondwater.The constructional tests that we carried out ourselves show that a mixture of sand and crushed aerated concrete is suitable for making a high-quality screed. This application has the great advantage that the leaching of the sulphates is not a problem, since screed has always been used in a completely dry environment separated from the groundwater.
Afhankelijk van de gewenste druksterkte kan een chapemengsel aangemaakt worden met 50 - 100 % gerecycleerd cellenbeton Doordat het de afzet van een afvalstof betreft, zal de prijszetting van het gerecycleerd cellenbeton gunstiger zijn dan voor primair zand.Depending on the desired compressive strength, a chapel mixture can be made with 50 - 100% recycled aerated concrete. Because it concerns the disposal of a waste material, the pricing of the recycled aerated concrete will be more favorable than for primary sand.
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 0/3 mm. Ter illustratie worden volgende zeefkrommes toegevoegd: 100% gerecycleerd cellenbeton (figuur 1), 25% rijnzand 0/3 met 75% gerecycleerd cellenbeton (figuur 2) en 50% rijnzand 0/3 met 50% gerecycleerd cellenbeton (figuur 3). De druksterkte die kan gehaald na 28 dagen worden varieert van 3 tot 8 Mpa (afhankelijk van de hoeveelheid toegevoegde cement) en is vergelijkbaar met de chapemengsels die heden al commercieel beschikbaar zijn.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 0/3 mm. As an illustration, the following sieve curves are added: 100% recycled aerated concrete (Figure 1), 25% Rhine sand 0/3 with 75% recycled aerated concrete (Figure 2) and 50% Rhine sand 0/3 with 50% recycled aerated concrete (Figure 3). The compressive strength that can be achieved after 28 days varies from 3 to 8 Mpa (depending on the amount of cement added) and is comparable to the chap mixes that are already commercially available today.
Voor de toepassing van het vermalen cellenbeton zal een gebruikscertifïcaat aangevraagd moeten worden bij de OVAM voor wat Vlaanderen betreft. 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.For the application of the ground cellular concrete, a user certificate must be requested from OVAM for Flanders. 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.
