| Abstract: | Regional materials in Lanzhou area are used to make standard concrete test blocks.The rebound and compression strength tests are performed on test blocks according to the technical regulations. And the relation between the concrete compression strength and the rebound value is investigated.Several mathematical models between rebound values and compression strength values are set up based on the regression analysis with least squares technique.The regional rebound curve is obtained to detect compression strength for Lanzhou area and the superiority of this regional curve is verified based on precision analysis and comparison with the coded national curve. Finally,several factors influencing the rebound curve are discussed. |
