Abstract

The invention consists of a mixing process where the known technique of forced mixing of the materials, in order to obtain homogeneity and penetration, is exchanged for a technique of mixing by the flow implying the use of the peculiarities of the materials, developed during the mixing process and that the peculiarity of the coarse fraction to develop a continuous flow in the mixer is utilized for spreading the other materials in even layers over the surface of the coarse fraction, were the water phase as a first layer on the coarse fractions surface, has the peculiarity to bind, to the surface of the flowing coarse fraction, an even layer of cement and filler and to penetrate the layer and thereafter spread layer of the fine fraction in one step and develop a continuous phase through the skeleton of aggregate particles and thereby disperse both large and small particles in a combined volume of suspension whereupon the peculiarities of dispersed particles develop the toughness in the glue phase of the cement concrete.

Description

502 752 2 utveckling av cementbetong genom att uppnå gemensam supensionen med cement och finfraktion i ett steg varvid betongens limfas visar sig bli seg. För att säkerställa denna seghet i betongen skall finfraktionspartiklarna tillsättes före det att vattenfasen brutit genom lagret av cementpartiklarna. 502 752 2 development of cement concrete by achieving the joint suspension with cement and fine fraction in one step whereby the adhesive phase of the concrete turns out to be tough. To ensure this toughness in the concrete, the fine fraction particles must be added before the water phase has broken through the layer of the cement particles.

Detta för att finfraktionspartiklarna skall bli neddammade av cementen, eftersom vattenfasens penetration genom finfraktion leds av dammet på finfraktionens partiklar.This is so that the fine fraction particles will be dusted off by the cement, since the penetration of the aqueous phase through fine fraction is led by the dust on the particles of the fine fraction.

Förfarandets resultat optimeras genom kalibrering av tidsintervallerna mellan tillsöttningarna av de olika komponenterna. Betongstationen skall därför vara försedd med anordning för; 1) val av individuell tidpunkt för de olika komponenternas tillsättning till blandaren. 2) val av flöde vid cemenfasens och finfraktionens tillsöttning till blandaren.The results of the process are optimized by calibrating the time intervals between the additions of the various components. The concrete station must therefore be equipped with a device for; 1) selection of individual time for the addition of the various components to the mixer. 2) selection of flow at the addition of the cement phase and the fine fraction to the mixer.

Dessutom skall insläppet vara så utformat och placerat att cementen sprids vid insläpp i blandaren och att, vid inslapp av finfraktionens material detta ankngter direkt till strömningen i blandaren.In addition, the inlet must be designed and positioned in such a way that the cement is spread when it is introduced into the mixer and that, when the material of the fine fraction is let in, this directly relates to the flow in the mixer.

Om filler ingår tillsätts det blandaren tillsammans med cementfasen. Um flgtmedel ingår tillsätts det före finfraktionen. Förfarandet kan tillämpas med modifierad cement och andra förekommande kemiska tillsättningsmedel.If filler is included, it is added to the mixer together with the cement phase. If a preservative is included, it is added before the fine fraction. The process can be applied with modified cement and other chemical additives.
