Evaluation method of frost damage repair effect

摘要

P To quantitatively evaluate a repair effect after repairing a frost damage by a patch repair method. PSOLUTION: A deposit strength is found in a repair execution time point by a procedure comprising the first step for obtaining preliminarily a relation expression between a relative dynamic modulus of elasticity of concrete and a length change rate thereof, and a relation expression between a length change rate of a repair material and the deposition strength thereof, and for acquiring the relative dynamic modulus of elasticity of the repair objective concrete, when executing the repair, the second step for finding the length change rate from the relative dynamic modulus of elasticity, based ON the relation expression between the relative dynamic modulus of elasticity of the concrete and the length change rate thereof and the third step for finding a relative deposit strength from the length change rate and based ON the relation expression between the length change rate of the repair material and the deposition strength thereof, an then the frost damage repair effect is evaluated based ON a decrease degree of the deposition strength from the repair execution time point up to the repair evaluation time point after the lapse of year, after finding the optional repair evaluation time point after the lapse of year and by the procedure comprising the first step-the third step.
