摘要: The use of alkali activated fly ash concrete (AAFAC) is an important step towards addressing two problems in the construction industry – environmental impact cement production and large landfills. In this study, AAFAC was prepared with class F from power plant 'Nikola Tesla B' Serbia a mixed activator consisting sodium silicate hydroxide solutions. experimental programme consisted three phases. First, eight pastes (AAFAP) different combinations mass ratio to 0.6 were tested order investigate their effect on compressive strength workability. second phase, four mixtures made one optimal solution additional water added study its workability strength. Finally, development through time. All samples oven-cured at 80°C for 6 hours. results concretes showed that can be used as binder activators.
