Preparation and characterization of foamed concrete using a foaming agent and local mineral resources from Burkina Faso
Alassane Compaoré, Moustapha Sawadogo, Youssouf Sawadogo, Moussa Ouedraogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine ZerboLightweight-foamed concretes (LFC) were formulated from cement, natural sand, and foam from a
foaming agent with densities of 600 and 700 kg/m3. The identified mineral phases in the cement are
alite, belite, celite, ferrite, calcite, and gypsum. The obtained foamed concretes have a porosity...
