Abstract. Selfcompacting concrete is one
of "the most revolutionar developement" in concrete research this concrete
is able to flow and to fill the most restacted places of the form work
without vibration. There are several methods for testing its properties
in the fresh state the most frequently used are slumflow test, Lbox
and Vfunnel.
This work presents properties of selfcompacting
concrete, mixed with different types additives fly ash, silica fume,
hydraulic lime and a mixture of fly ash and hydraulic lime.
Key words: Selfcompacting concrete,
slumflow test,Vfunnel fly ash, hydraulic lime
SVOJSTVA SAMOUGRAĐUJUĆEG BETONA
SA RAZLIČITIM DODACIMA
Samougrađujući beton je jedno od "najrevolucionarnijih
otkrića" u razvoju tehnologije betona; ovaj beton može da teče i da
ispuni i teško dostupne oplate bez vibriranja. Postoji više metoda za
ispitivanje njegovih svojstava u svežem stanju najšeće koričćene
su slumflow test, Lbox and Vfunnel.
U ovom radu su pokazana svojstva samougrađujućeg
betona sa različitim dodacima: letećim pepelom, silikatnom prašinom,
krečnim brašnom i mešavinom letećeg pepela i krečnjačkog brašna.
