摘　　要：研究了混凝土回弹仪钢砧率定值与其硬度及质量间的关系,确定了一款比较适合中型回弹仪用的轻型钢砧(率定值为40±1)。结果表明:该轻型钢砧可有效提升回弹仪检定周期内常用示值区间段回弹值的重复性、稳定性和准确性,同时,可确保回弹仪的使用过程处于标准状态,进而提高回弹法检测混凝土抗压强度的精度。Based on the study of the relationship between the setting value of steel anvil and its hardness and weight,a light steel anvil with the setting value of 40±1 was determined.The results show that the light steel anvil can effectively improve the repeatability,stability and accuracy of the rebound value of commonly used indication interval in the verification cycle of the rebound instrument.In addition,it can ensure that the use process of the rebound instrument is in a standard state,thereby improving the accuracy of the rebound method for testing the compressive strength of concrete.
