Mechanical Behavior of Workable Bio-Based Cementitious Composites for Construction Materials

This study presents the results of a wide experimental campaign aimed at characterizing the physical and mechanical response of sustainable cementitious composites produced different types of bio-aggregates (i.e., bamboo particles, wood shavings and rice husk). First of all, based on the specific physical and geometrical properties of the bio-aggregates, an adapted mixing process was performed in order to warranty an adequate moldability. Then, the stress-strain behavior of the hardened samples was investigated up to 28-days by unveiling the influence of the several types of particles on the resulting mechanical response. The results proposed herein demonstrate the high potential of the bio-concretes for being employed as an innovative and sustainable construction materials.
