Tvångsblandare är kostsama och stora och få privatpersoner och mindre företag har möjlighet att hålla sig med en sådan. Samtidigt har detta material så stora byggnadstekniska fördelar att det är intressant även på konsumentmarknaden. Problemet som föreliggande uppfinning avser att lösa är att åstadkomma en konsumentprodukt som med säkerhet ger de positiva egenskaper som kan fås på stora byggen.Forced mixers are costly and large and few private individuals and smaller companies have the opportunity to stick with one. At the same time, this material has such great building technical advantages that it is also interesting in the consumer market. The problem which the present invention seeks to solve is to provide a consumer product which certainly provides the positive properties that can be obtained on large buildings.
Detta problem har många försökt lösa de senaste fem åren men inte lyckats med förrän nu.Many have tried to solve this problem for the past five years but have not succeeded until now.
SSAMMANFATTNING AV UPPFINNINGEN Uppfinningen löser problemet genom ett tillverknings- förfarande enligt patentkrav 1 och en konsumentprodukt enligt patentkrav 6.SUMMARY OF THE INVENTION The invention solves the problem by a manufacturing method according to claim 1 and a consumer product according to claim 6.
Tack vare uppfinningen är cementen redan jämnt fördelad i förhållande till cellplasten då vatten ska tillsâttas för att bilda lâttbetongmassan. Det betyder att konsumentprodukten kan blandas med vatten i exempelvis en hink och det räcker med att röra runt med en pinne för att massan ska bli homogent blandad och därmed ge önskade -. u- mm, 10 15 20 25 30 » ø 1 - v, nu u. a v o nu H n u. o. s nn u nu nu n n n n o H i I *w .u . . f f. v u .» -. u. - - n n e n v n v n n a. u ~ v n u n . ~ u. n u ...I » 3 egenskaper hos materialet. Om materialet inte är homogent blandat kommer olika delar av lättbetongen ha olika tekniska egenskaper. Framförallt kommer hållfastheten att fluktuera i materialet, vilket är mycket negativt.Thanks to the invention, the cement is already evenly distributed in relation to the foam when water is to be added to form the lightweight concrete mass. This means that the consumer product can be mixed with water in, for example, a bucket and it is enough to stir with a stick for the mass to be homogeneously mixed and thus give the desired -. u- mm, 10 15 20 25 30 »ø 1 - v, nu u. a v o nu H n u. o. s nn u nu nu n n n n o H i I * w .u. . f f. v u. » -. u. - - n n e n v n v n n a. u ~ v n u n. ~ u. n u ... I »3 properties of the material. If the material is not homogeneously mixed, different parts of the aerated concrete will have different technical properties. Above all, the strength will fluctuate in the material, which is very negative.
Uppfinningens kärna är att cellplasten i sig binder cementet till sig.The core of the invention is that the cellular plastic itself binds the cement to itself.
DETALJERAD BESKRIVNING AV EN FÖREDRAGEN UTFÖRINGSFORM För att tillverka en konsumentprodukt som innefattar en cement- och cellplastblandning börjar man med att finfördela, exempelvis genom rivning, cellplast, företrädesvis expanderad polystyren, till partiklar, exempelvis i storleksordningen 5-8 mm. Företrädesvis antistatbehandlas och härdas den finfördelade cellplasten.DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT To manufacture a consumer product comprising a cement and foam mixture, one begins by atomizing, for example by tearing, foam, preferably expanded polystyrene, into particles, for example in the order of 5-8 mm. Preferably, the atomized foam is antistatic treated and cured.
Den finfördelade cellplastens yta måste behandlas så att den smälter, varvid ytan blir klibbig. Detta kan ske genom upphettning av ytan medelst exempelvis varmluft.The surface of the atomized foam must be treated so that it melts, making the surface sticky. This can be done by heating the surface by means of, for example, hot air.
Upphettningen av ytan kan också ske genom en kemisk reaktion på ytan mellan en kemikalie och cellplasten.The heating of the surface can also take place by a chemical reaction on the surface between a chemical and the foam.
Cellplastpartiklarnas yta bör uppnå en temperatur av 45-60 °C, företrädesvis 50-55 °C, för att bästa vidhäftning ska uppnås mellan cement och cellplastyta. Dä rätt temperatur uppnåtts på cellplastytan blandas den finfördelade cellplasten med cement, varvid cementen fäster vid cellplastens yta, närmare bestämt runt hela ytan på varje partikel av cellplasten.The surface of the foam particles should reach a temperature of 45-60 ° C, preferably 50-55 ° C, in order to achieve the best adhesion between cement and foam surface. When the correct temperature has been reached on the foam surface, the atomized foam is mixed with cement, the cement adhering to the surface of the foam, more specifically around the entire surface of each particle of the foam.

Den färdiga produkten enligt uppfinningen innefattar alltså partiklar av cellplast som omges av cement.The finished product according to the invention thus comprises particles of cellular plastic surrounded by cement.
Konsumenten blandar sedan produkten enligt uppfinningen med vatten, varvid en.homogen blandning av cement och cellplast uppstår automatiskt då allt cement blivit fuktat. Därefter kan konsumenten gjuta efter eget önskemål något som ger en lättbetong som torkar på 1-3 dygn.The consumer then mixes the product according to the invention with water, whereby a homogeneous mixture of cement and cellular plastic arises automatically when all the cement has been moistened. After that, the consumer can cast according to their own wishes something that gives a lightweight concrete that dries in 1-3 days.
