ABSTRACT
The aim of the present study, an attempt to shed light on the use of industrial-based wastes as alkali-activated binder (AAB) material is mainly. The present novel research work, the characterization of waste ferrochrome slag (FCS) and the performance of alkali-activated mortar consisting of fly ash (FA) were investigated. The characterization of used materials were carried out using advanced microstructural analysis techniques (XRF, XRD and SEM). A total of thirty two mortars are prepared using FCS (90-60%) and FA (10-40%) with 5 M, 10 M sodium hydroxide (NaOH), Na2SiO3/NaOH (SS/SH = 1 and 2) solution. All specimens were cured in an oven at 70 °C and 100 °C for 24 h. After oven curing, the geopolymer mortars were kept in the laboratory for 28 days and thermal and mechanical tests were applied to them. The A5 mixture (SS/SH = 1 with 10%FA, 90%FCS and 5 M NaOH) was found to be optimum in terms of thermal insulation properties, making it suitable for use in sustainable construction in terms of low energy cost through exterior insulation. The C8 mixture (SS/SH = 1 with 40%FA, 60% FCS and 10 M NaOH) was found to be optimum in terms of strength and durability, making it suitable for use in sustainable construction. As a result, in this study, an optimum mixture of waste FCS and FA was obtained and geopolymer building materials that provide thermal insulation and structural performance and are resistant to external influences were produced.
