Effect of mineralogical substitution raw material mixing ratio on mechanical properties of concrete
The aim of the original research was to examine and discuss the effects of mineralogical substitution raw material mixing ratios on some mechanical properties of concrete. In this study, fine-particle marble-cutting remnants and fine-particle burnt-clay brick remnants, fine and coarse crushed aggregate, CEM I 42.5N cement and tap water are used as concrete mixing materials. The mineralogical raw substitution material mixing ratio is an independent variable for concrete strength properties. Three substituted concrete groups and one control concrete group were prepared with and without substitution of fine-particle marble-cutting remnants and/or fine-particle burnt-clay brick remnants. The 7-, 14-, 28-, and 90-day compressive strength and flexural strength of concrete were measured with regard to the effects of the mineralogical raw substitution material mixing ratio. The findings unveil that the mineralogical raw substitution material mixing ratio can have positive effects on some mechanical stress factors affecting concrete.
