  • 摘要:The utilization of cement in concrete was an ancient method as well the utilization of cementitious materials in concrete not only improves mechanical properties but also improves workability and durability etc., Today urbanization expands in many folds, so that the usage of cement became more due to this the production of cement increases. The production of cement on one hand affects the environment in form of Carbon dioxide gases on other hand depreciation of raw materials like lime stone and sand etc. Globally many construction industry and researches focussed in reduction of cement content in concrete by production of new alternatives like Geo polymer concrete etc. In this investigation Alkali-Activated Fly Ash slag concrete (AAFSC) is introduced as an alternative for ordinary Portland cement concrete (OPCC). Researchers developed AAFSC with NaOH and Na2SiO3 as activators. In this study AAFSC produced is with neutral grade sodium silicate solution with silica modulus 2.9 (Ms).For production of AAFSC the quantity of binder content is 500kg/m3 by varying binders proportions like Fly Ash and GGBS along with solution/binder ratios varying from 0.6 to 0.7. During this experimental investigation the workability and compressive strength of AAFSC is tested.
