Web15 Oct 2024 · The tensile strength of concrete was measured on 21 cubes 150/150/150 mm at a splitting test. The obtained mean value of splitting tensile strength was f_\mathrm {ct,sp}=1.64~\hbox {MPa} (standard deviation s=0.18~\hbox {MPa} ), and the axial tensile strength was calculated as f_\mathrm {ct}=0.9 f_\mathrm {ct,sp} =1.48~\hbox {MPa}. WebThe theoretical compressive strength of concrete is eight times larger than its tensile strength. This implies a fixed relation between the compressive and tensile strength of concrete. In fact there is a close relation but not a direct proportionality. The ratio of tensile to compressive strength is lower for higher compressive strengths. WebThe magnitude of this tensile stress O sp (acting in a direction perpendicular to the line of action of applied loading) is given by the formula (IS : 5816-1970): O sp = 2P = 0.637 P/dl ∏dl The ratio of the split tensile strength to … lawngevity lawn service fremont ne
