关于回弹法检测与结构实体混凝土强度验收的探讨

回弹法是测定混凝土表面砂浆层硬度来捧定强度.而表面硬度与强度没有直接的、统一的、固定的关系.更何况混凝土是一种复杂的多相非均质性材料,其硬度与强度之间更没有稳定统一的相关性.因此,采用同弹法测定的混凝土强度存存较大误差,并非科学、准确、合理的方法.参考并引用了混凝土领域多位专家、学者及工程技术人员的观点和资料.并结合笔者多年工作经验与试验研究,介绍了回弹法榆测和结构实体混凝土强度验收存在的问题,希望引起迷信同弹法测强人员的思考,减少错判误判问题的发生.

Testing on rebound method and receiving inspection of the strength of the integral concrete structure

The rebound method is used to test the hardness of the surface motor and estimating the strength of concrete.But there no direct,unified and stable relationship between the surface hardness and compressive strength of concrete.The concrete is a kind of comprehensive and highly heterogeneous body,so it,s hardness and strength has no stable and unified relativity.Thus the rebound method exists bigger inaccuracy and isn't scientific,exact,logical method.Consulting and quoting to viewpoints and data of lots of ...
