A compression test of a standard 6" times 12" concrete cylinder was conducted at 28 days. The axial deformation was measured over a gauge length of 4". Following are the test data. Use the test data to: a) Plot the stress-strain .
An unconfined compression test was performed to determine the average strength of con- crete cylinders (in psi). It is believed that the strength is approximately normally dis- tributed with a standard deviation of 196 psi. A sample of 50 concrete cylinders was taken, and it was found that the average strength was 2500 psi.A compression test along the length (z-direction) of a cylinder of unreinforced concrete gives an ultimate strength of -26 Mpa and the fracture surface is at a 25.2-degree angle to the loading direction. A tension test along the x direction gives the ultimate tension strength of 2.6 Mpa.
