    摘要: PURPOSE: A method for evaluating compressive strength of structural concrete is provided to efficiently manage a construction process and to improve reliability of concrete quality. CONSTITUTION: A method for evaluating compressive strength of structural concrete comprises: a step of making a test piece having sample mixing condition with the structural concrete; a step of checking curing period and compressive strength of the test piece to draw accumulated temperature-compressive strength relation graph; a step of measuring the temperature by each curing period of structure concrete built in a form to calculate the accumulate temperature; and a step of estimating compressive strength of the structural concrete.
