Zagreb clay improved with various binders

The paper presents the results of laboratory testing clay samples from two localities in city Zagreb, mixed with fly ash, slag and cement. Under conditions, composite mixtures binders were prepared, where are added to ratios 5 %, 10 % 20 tested at different maturation time intervals 7, 14 28 days. influence type amount binder age sample on moisture uniaxial compressive strength was examined analysed. obtained show that utilization cement, ash can improve physical mechanical properties Zagreb clay, depending composite.
