عنوان انگلیسی Eco-friendly Blocks by Blended Materials
چکیده انگلیسی مقاله In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ash and ground granulated blast furnace slag (GGBS) are used as source materials. Since fly ash and GGBS are industrial wastages which are non-renewable in nature, quarry dust is used as the partial replacement that is 50% in weight with fine aggregate. Soluble activators like Sodium hydroxide (NaOH) and Sodium silicate (Na2SiO3) of 12M are used instead of water in the ratio of 1:2.5. Different mix proportions are considered in this study such as F80G20, F70G30 and F60G40. These mix proportion results were compared with conventional concrete of M20. The results were drawn for different strength tests such are Compressive strength test, Split Tensile strength test and Flexural strength test. From the results it is concluded that F60G40 mix has high Compressive strength, Split Tensile strength and Flexural strength compared to remaining mixes along with conventional concrete.
