The composition of FA and ASP used for cement replacement were 0%, 10% ASP, 30% FA, 10% ASP+30% FA, 10% ASP+40% FA, and 10% ASP+50% FA. The water-cement factor (FAS) and binder used are 0.3 and 500 kg/m3 fresh concrete, respectively. The specimens used for compressive strength is cubes of 100×100×100 mm with tests at the age of 1, 3, 7, 28, and 56 days. The results showed that the use of 10% ASP increased the compressive strength of the concrete compared to the control concrete but required more superplasticizers. The use of 30% FA as a cement substitute showed a decrease in compressive strength compared to control concrete but reduced the use of superplasticizer. The use of a combination of FA and ASP as a substitute for cement showed a decrease in compressive strength under control concrete and concrete using 30% FA. The...

Ecofriendly and economic concrete for heavily loaded structure. Significantly higher modulus of resilience and toughness of PSC concrete than NWC. Higher Displacement and torsional ductility of PSC concrete element compared to NWC element. Torsional ductility always higher than displacement ductility of PSC concrete element.
