Study of Fly Ash in Making Cementitious Composites

Abstract:

Applications of fly ash in building industry have very important and relevant problems of origin which are discussed in this paper. Authors have performed tests on mortar, plain concrete and Self Compacting Concrete (SCC) specimens. Experiments showed satisfactory results concerning possible application of fly ash as admixture for cementitious composites. Experimental research was conducted in the Laboratory for materials at the Faculty of Civil Engineering, University of Belgrade.
