Polimerni materijali u betonu

, 25. 2004

Razlikujemo četiri vrste betona koji sadrže polimere: (1) polimer beton (PB), (2) polimerima modifikovani beton (PMB), (3) polimerima mikro armirani beton (PMAB) i (4) polimerima impregnisani beton (PIB). PB se formira polimerizacijom mešavine monomera i agregata. PMB se dobija dodatkom monomera ili polimera u svežu portland cementnu betonsku mešavinu, a koji naknadno vulkanizuje i polimerizuje posle ugrađivanja betona. PMAB se dobija dodatkom polimernih vlakna (npr. polipropilenska)u svežu portland cementnu betonsku mešavinu koja se nakon mešanja ugrađuje, čime se postiže mikro armiranje betona. PIB se dobija impregnacijom očvrslog portland cementnog betona sa tečnim monomerima i naknadnom polimerizacijom tog monomera in-situ.

POLYMER MATERIALS WITHIN THE FRAMEWORK OF CONCRETE

SUMMARY

We are differentiating four types of concrete which are containing the polymers: (1) polymer concrete(PC), (2) polymer modified concrete (PMC), (3) polymer micro reinforced concrete (PMRC) and (4) polymer impregnated concrete (PIC). PC is created through the polymerization of the mixture made of monomers and aggregates. PMC is obtained through the addition of monomers or polymers into a green portland cement concrete mixture, which are subsequently vulcanized and polymerized after the concrete setting. PMRC is obtained through the addition of polymer fibers (e.g. polypropylene) into a green portland cement mixture being set after the mixing, whereby one is obtaining a micro reinforcement of concrete. PIC is obtained through the impregnation of consolidated portland cement concrete with liquid monomer and subsequent in-situ polymerization of that monomer.
