Abstract

Fill and ground binding agent comprises (by wt.%) cement 1-30 pref. 1-15, more pref. 7-10; and waste (I) 99-70, (I) being fly ash or prods. of de-sulphurisation of granulated blast-furnace slag, mixed with water and/or air, pref. fly ash 99-85 pref. 93-90. The compsn. pref. contains water to a water binder index (water/(cement + fly ash) of 0.20-0.60 pref. 0.38.

Description

452 312 Konsistensen på blandningen styres med vattenbindemedelstalet, exempelvis så att blandningen kan pumpas in i kaviteter som är mer eller mindre svåra att fylla upp, eller så att massan kan skyfflas ner i gropar och hål. 452 312 The consistency of the mixture is controlled by the water binder number, for example so that the mixture can be pumped into cavities that are more or less difficult to fill, or so that the mass can be shoveled into pits and holes.

Hållfastheten varieras med cementmängden och beror även av vat- tenbindemedelstalet.The strength varies with the amount of cement and also depends on the water binder number.

Flygaskan fungerar som en fin ballast vid cementens hydratation och förhindrar sådan uppsprickning som skulle ske vid använd- ning av vanlig betong till fyllning. Kostnaden för betong omöj- liggör för övrigt också dess användning som fyllning för de all- ra flesta ändamål.The fly ash acts as a fine ballast during hydration of the cement and prevents such cracking that would occur when using ordinary concrete for filling. The cost of concrete also makes it impossible to use it as a fill for most purposes.

Många typer av flygaskor är däremot ett mycket billigt avfalls- material och det är därför ekonomiskt möjligt att använda vår fyllmassa för en mångfald olika ändamål, där den aktuella, komp- lexa byggnadstekniken behöver ett lätt borttagbart fyllningsma- terial med styrbar densitet, varigenom kostnaderna för arbete och utrustning kan minskas och arbetet går snabbare. '” Sålunda lämpar sig vår fyllmassa utmärkt för fyllning av upptag- ningar i vägar och gator, såväl i tvär- som längsriktningen, som fyllning i rörgravar och som avjämningsbädd för rörledningar, för fyllning av sönderrostade underjordstankar och gropar, som fyllning i håligheter under golv och vägar, och även som belägg- ning på deponerade avfallshögar för att förhindra urlakning av olika giftiga och skadliga ämnen.Many types of fly ash, on the other hand, are a very cheap waste material and it is therefore economically possible to use our filling compound for a variety of different purposes, where the current, complex building technology needs an easily removable filling material with controllable density, whereby the costs for work and equipment can be reduced and work goes faster. '”Thus, our filling compound is excellent for filling catchments in roads and streets, both in the transverse and longitudinal directions, as filling in pipe trenches and as a leveling bed for pipelines, for filling broken underground tanks and pits, as filling in cavities under floors and roads, and also as a coating on landfilled waste heaps to prevent leaching of various toxic and harmful substances.

Förutom att fyllmassan är sättningsfri och icke ändrar sin volym är den också möjlig att använda i alla slags väder och lätt att avlägsna även efter lång tid. Den är sålunda möjlig att "skära" bort med grävmaskin eller till och med med spadar.In addition to the filling mass being sediment-free and not changing its volume, it is also possible to use in all kinds of weather and easy to remove even after a long time. It is thus possible to "cut" off with an excavator or even with shovels.

Tillverkningen av fyllmassan kan ske i vanliga cementblandare, antingen industriellt för transport som färdigblandad, pumpbar fyllmassa eller direkt på arbetsplatsen i mindre cementblandare.The filling mass can be manufactured in ordinary cement mixers, either industrially for transport as ready-mixed, pumpable filling compound or directly at the workplace in smaller cement mixers.

Ett annat alternativ är att tillsätta de olika komponenterna i en roterbil, varefter blandning sker under den tid, då massan transporteras till arbetsplatsen.Another alternative is to add the various components in a rotary truck, after which mixing takes place during the time when the pulp is transported to the workplace.

1. 452 312 Patentkrav Användning av fyllmassa med en sammansättning av 1 ~ 15 vikt% cement 99-85 vikt% flygaska och vatten till ett vattenbindemedelstal av 0,30-0,60 som täckningsmaterial pà deponerade avfallshögar, soptippar och dylikt eller som inblandningsmassa i miljöfarligt avfall för att binda materialet och därigenom förhindra urlakning av skadliga och giftiga vattenlösliga ämnen.Use of filling compound with a composition of 1 ~ 15% by weight of cement 99-85% by weight of fly ash and water to a water binder number of 0.30-0.60 as a covering material on deposited waste heaps, landfills and the like or as a mixing compound in environmentally hazardous waste to bind the material and thereby prevent leaching of harmful and toxic water-soluble substances.
