表层区的混凝土强度试验Ｊ．Ｈ．Ｂｕｎｙｅｙ（利物浦大学土木工程系）一、引言对确定现场混凝土强度这一问题，工程师们可从各种试验方法中作出选择，一种方法是钻取芯样，这种方法可靠，但取样和试验速度较慢，结构物受到破损，且应用上也有一定限制。另一种方法是回弹... Concrete surface strength test area J. H. Bunyey (Department of Civil Engineering, University of Liverpool) I. INTRODUCTION Engineers can choose from a variety of test methods to determine the strength of concrete in the field. One method is to drill a core sample, which is reliable but sampling and testing Slower, the structure is damaged, and there are some restrictions on the application. Another way is to rebound ...
