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.
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.
