Abstract EN
Illito-kaolinitic clay rich in hematite from south Tunisia was investigated in view of producing geopolymer materials.
Geopolymers with two different densities were elaborated: cement and foam.
The effects of activator concentrations on compressive strength, water absorption (durability), open porosity, and bulk density of geopolymers cement were examined, in order to assure optimal geopolymerization conditions.
Geopolymer cements aged 28 days with optimum performances were achieved for 13 M of alkaline solution concentration.
At these conditions, the compressive strength of prepared geopolymer reaches 27.8 MPa.
The addition of silica fume to reactant geopolymer mixture induces modification of geopolymer density and decrease in the compressive strength of the final product.
Geopolymer materials based on calcined Tunisian clay can be suggested as sustainable and cost-effective cement that may be applied to alternate Portland cement in many construction applications.
