Mineral foams obtained with super sulfated cement
Résumé
The purpose of this study is to evaluate the performances of Super Sulfated Cement (SSC) foams, focusing on structural, thermal and mechanical characteristics. The studied set of SSC foam samples is obtained with the same slurry. The chosen foaming method allows an interesting density variation: from 489 kg/m3 to 1793 kg/m3. Thanks to a CCD camera, the visual study of foam pore structure reveals two kinds of bubbles distribution and associated connectivity. This may partially explain the obtained thermal and mechanical behavior. Results show that SSC foams with low density (< 550 kg/m3) are usable as thermal insulator for non-loadbearing wall. Mean density SSC foams (550 kg/m3 < < 640 kg/m3) can be used 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.
