Properties of self-compacting concrete with different types of additives

Abstract

Self-compacting concrete is one of 'the most revolutionar development' 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 it's properties in the fresh state: the most frequently used are slum-flow test, L-box and V-funnel. This work presents properties of self-compacting concrete, mixed with different types additives: fly ash, silica fume, hydraulic lime and a mixture of fly ash and hydraulic lime.Samougradjujuci beton je jedno od 'najrevolucionarnijih otkrica' u razvoju tehnologije betona; ovaj beton moze da tece i da ispuni i tesko dostupne oplate bez vibriranja. Postoji vise metoda za ispitivanje njegovih svojstava u svezem stanju: najcesce koriscene su slum-flow test, L-box and V-funnel. U ovom radu su pokazana svojstva samougradjujuceg betona sa razlicitim dodacima: letecim pepelom, silikatnom prasinom, krecnim brasnom i mesavinom leteceg pepela i krecnjackog brasna.
