Our results show that the C-LWA produced by pelletization and cold-bonding can be used in a similar way as conventional LWA. Although concrete with C-LWA exhibits lower mechanical properties compared to concrete with normal-weight aggregates, this effect is to be expected considering the introduced porosity and is well known for concretes with regular LWA . The reduction of strength caused by the introduction of the C-LWA (with estimated increase in porosity by 9% of porosity) can be analyzed from the point of view of the reduced density of concrete. In , the reduction of density by 1% corresponded to about 3% reduction in compressive strength. These results were however obtained for high strength lightweight concrete; they are thus not necessarily relevant for the normal-weight concrete studied here. For the C-LWA saturated concrete (where the effective w/c was nominally equal to that of the reference concrete), the reduction of density by 1% corresponds to about 2% loss in strength.
