New Equations to Calculate Failure Stress and Strain of Concrete
The gravel geometry (shape and size of aggregate), and water to cement ratio affect the constitutive law of concrete. In concrete technology, it is intended to increase the failure stress and strain for enhancing the seismic performance during the earthquake. The aim of the present study is to propose mathematical equations that the independent variables are aggregate size and water to cement ratio. These equations evaluate the failure stress and strain of plain concrete in compressive behavior. The samples were prepared to cover a varied range of compressive strength from 17 to 37 MPa. Two sets of samples were selected, the rounded and sharp aggregates with a variety of sizes (9.5, 12.5, 19, and 25 mm) and water to cement ratios (0.35, 0.42, 0.54, and 0.76). Error analysis shows that the proposed relations are intolerable agreement with the test results and the models suggested by the other researchers, especially regarding failure stress.
