Development of construction materials from the geopolymerization of red clay and coal fly ash

Red clay contains solid aluminosilicate has been shown to be reactive in the presence of an alkaline activator. The addition coal fly ash and lime improvements their mechanical physical properties geopolymer products. FTIR analysis SEM images product have formation gel geopolymeric product. maximum compressive strength products GP-RFL was achieved 15.92 N/mm2 having water absorption 10.47 % bulk density 2.81 g/cm3. These results indicated that mortars made from red clay, could used as alternative construction material./p> BIBECHANA 19 (2022) 119-126
