摘　　要：由于国家统一测强曲线的建立,为应用普通混凝土工程后续质量检测提供了许多理论支撑和实际应用便利,但是对轻骨料混凝土测强曲线的建立还研究尚少。建立测强曲线可以得到混凝土在役或者退役时的抗压强度,对后续混凝土质量进行检验。基于国内外应用无损检测技术方法,得到各种不同类型的混凝土测强曲线方程,以此作为开展研究轻骨料混凝土测强曲线的发展背景。对该领域研究的理论成果所得到的测强曲线进行集中梳理,同时,也为将来轻骨料混凝土强度推定曲线的建立奠定了研究基础。The establishment of national unified strength testing curve has provided theoretical support and practical application convenience for the following quality inspection of many ordinary concrete projects.However,there is still little research on the establishment of lightweight aggregate concrete strength testing curve.The compressive strength of concrete in service or decommission g can be obtained by establishing the strength curve,and the quality of subsequent concrete can be tested.The purpose of this paper is to obtain various types of concrete strength curve equations through the research on the application of nondestructive testing technology and methods at home and abroad,which is used as the development background for the research on the strength curve of lightweight aggregate concrete.The strength curves obtained from the theoretical results of some previous studies are reviewed,and the research foundation is laid for the establishment of the strength presumption curve of lightweight aggregate concrete in the future.
