摘　　要：以某实际工程建设项目为依托,对该工程中使用的混凝土进行了试验研究,通过对回弹法测算出混凝土试件的表面强度与采用钻芯测得的试件内部强度进行分析,得出了两者之间的强度关系曲线,并对专用测强曲线强度进行了验证,结果表明,回弹专用测强曲线得到的强度值更接近芯样的抗压强度。Based on the construction program of some project,the paper undertakes the test research on the concrete used in the construction,analyzes the surface strength of the concrete test specimen with the rebound method and the inner strength on the specimen with the drilled core method,concludes the strength relation curve of the two methods,proves the strength of the special strength curve,and proves by the result that the strength value obtained by the rebound special strength measuring curve is close to the compressive strength of core samples.

关 键 词：混凝土强度 回弹强度 芯样强度
