Mineral foams obtained with super sulfated cement

Résumé

The purpose of this study is to evaluate the Super Sulfated Cement (SSC) foams performances, focusing on structural, thermal and mechanical characteristics. The studied set of SSC foam samples is obtained with the same slurry but the chosen foaming method allows density variation: 489 kg/m3 to 1793 kg/m3. Thanks to a CCD camera, the pore structure of all of SSC foam samples is described. It reveals two kinds of bubbles distribution and associated connectivity. This may in part explain the thermal and mechanical behavior obtained. Results show that SSC foams with low density (< 550 kg/m3) are usable as thermal insulator for non-loadbearing wall, SSC foams with mean density (550 kg/m3 <  < 640 kg/m3) as slight-loadbearing and thermal insulating products in housing and SSC foams with high density (640 kg/m3 <  < 1200 kg/m3) as loadbearing products staying within lightweight class.
