Abstract

ABSTRACT This paper reports a laboratory implementation of a prototype sensor for the measurement of in situ concrete static modulus of elasticity. Sensor measurements for a trial concrete mixture were generated, post-processed, and calibrated to best match companion ASTM C469 modulus of elasticity testing performed on the same mixture for concrete ages up to 28 days. The sensor prototype measurements demonstrated close agreement with ASTM C469 testing with approximately 90% of calibrated sensor prototype measurements within ±5% of companion testing. The initial sensor prototype implementation reported in this study affirms the feasibility of in situ concrete modulus of elasticity measurement and justifies further sensor development and implementation efforts.

混凝土静态弹性模量的原位测量:概念实现的证明

本文报道了一种用于测量现场混凝土静态弹性模量的原型传感器的实验室实现。对试验混凝土混合物的传感器测量值进行了生成、后处理和校准，以最佳地匹配ASTM C469对同一混合物进行的长达28天的混凝土龄期弹性模量测试。传感器原型测量结果与ASTM C469测试结果非常吻合，大约90%的校准传感器原型测量结果在±5%的伴随测试范围内。本研究中报告的初始传感器原型实现肯定了原位混凝土弹性模量测量的可行性，并证明了进一步的传感器开发和实现努力。

期刊介绍： Research in Nondestructive Evaluation® is the archival research journal of the American Society for Nondestructive Testing, Inc. RNDE® contains the results of original research in all areas of nondestructive evaluation (NDE). The journal covers experimental and theoretical investigations dealing with the scientific and engineering bases of NDE, its measurement and methodology, and a wide range of applications to materials and structures that relate to the entire life cycle, from manufacture to use and retirement. Illustrative topics include advances in the underlying science of acoustic, thermal, electrical, magnetic, optical and ionizing radiation techniques and their applications to NDE problems. These problems include the nondestructive characterization of a wide variety of material properties and their degradation in service, nonintrusive sensors for monitoring manufacturing and materials processes, new techniques and combinations of techniques for detecting and characterizing hidden discontinuities and distributed damage in materials, standardization concepts and quantitative approaches for advanced NDE techniques, and long-term continuous monitoring of structures and assemblies. Of particular interest is research which elucidates how to evaluate the effects of imperfect material condition, as quantified by nondestructive measurement, on the functional performance.
