| Abstract |
This study conducts core experiment with the making and curing of testing wall and mould in in-situ concrete, compares the strength of the concrete used in actual building to the compression strength of mould, carries out the non-destructive test according to the progress of age, makes the estimation expression and then examines the reliability of the expression by comparing and anayzing the estimated compression strength with the compression strength and estimated expression by the core. In addition, it investigates the test determinants of non-destructive measurement values of the curing method and the estimation of concrete strength and the rate of error and cancellation relation according to the estimation of strength and aims at providing the basic materials the combined non-destructive testing method for the quality control of read-mixed concrete and the estimation of strength of in-situ concrete can be used. |
