The Tensile-Compressive Strength Relationships of Concrete Containing Waste Materials

Utilizing waste materials as an alternative for cement in concrete to reduce its harmful effects on the environment to produce green concrete is interesting for researchers. In this paper, an experimental database including compressive and tensile strength of green concrete, containing Limestone, Granite, Marble and Red Mud powder as waste materials, was collected from literature and with the nonlinear regression (NLR) technique, the tensile-compressive strength relationships in different curing times of ۲۸, ۵۶ and ۹۰ days was predicted. The results showed that the tensile-compressive strength relationship for ۹۰ days of curing time with R۲ value of ۰.۷۴۲۴ is the most accurate predicted relationship in comparison to other relationships designated to different curing times.
