In this work a granular cementitious composite has been developed whose performance has to be characterized by low compressive strength and high deformation and energy dissipation capacity. This can be achieved by uniform grain size distribution, paste content as low as minimum theoretical void ratio and low paste strength, so to allow for energy dissipation after paste cracking due to both rearrangement of grain meso-structure and, in case, grain crushing. This study details the optimization of the material composition, in terms of w/c ratio, content of air entraining agent, mixing protocol, paste volume fraction, grain size distribution of the lightweight ceramic aggregate (LWA), and the static characterization.

Abstract

In this work a granular cementitious composite has been developed whose performance has to be characterized by low compressive strength and high deformation and energy dissipation capacity. This can be achieved by uniform grain size distribution, paste content as low as minimum theoretical void ratio and low paste strength, so to allow for energy dissipation after paste cracking due to both rearrangement of grain meso-structure and, in case, grain crushing. This study details the optimization of the material composition, in terms of w/c ratio, content of air entraining agent, mixing protocol, paste volume fraction, grain size distribution of the lightweight ceramic aggregate (LWA), and the static characterization.
