Provedena su istraživanja kako bi se odredila svojstva obradljivosti betona u kojem su pepeo šećerne trske i rižinih ljuski korišteni kao djelomična zamjena za cement. Pripremljene su i ispitane probne mješavine s različitim vodocementnim omjerom, različitim udjelom zamjenskih materijala, različitom količinom superplastifikatora i stabilizatora mješavine. Na temelju dobivenih rezultata određeni su omjeri za tri optimalne betonske mješavine koje zadovoljavaju zahtjeve za samozbijajući beton koji se može koristiti za različite konstrukcijske namjene.
In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proportions, which comply with the self-compacting concrete requirements for several structural applications.
