Performance of alkali-activated slag concrete
Environmental about the high energy consumption and huge emissions of CO2 associated with the production of Portland cement are leading to the search for more environmentally viable alternatives to Portland cement. One of these altemative materials is alkali-activated slag (AAS) in which ground, granulated blast furnace slag is used not as a partial replacement to cement but as a binder in itself in the production of concrete. This paper presents results of tests carried out to study the performance of alkali-activated slag concrete using sodium silicate (water glass) as an activator in Na2O dosages of 4 % and 6 %. The fresh concrete properties (setting time, workability and air content) were examined in addition to the engineering properties (compressive strength, splitting tensile strength, drying shrinkage, dynamic modulus of elasticity and ultrasonic pulse velocity). Hydration products were identified using XRD.
