Abstract
The moisture content of concrete affects the ultrasonic pulse velocity and compressive strength. This effect adversely affects the estimation of the concrete compressive strength by ultrasonic testing. Therefore, this study conducted ultrasonic and compressive tests on dry concrete specimens. By applying the measured experimental results, this study proposed an estimation equation for concrete compressive strength that considers the effect of the moisture content. The proposed equation can estimate the compressive strength of dried concrete, concrete that has been dried and underwater curing again, and concrete that ha s been cured under standard curing conditions with an accuracy of about ±20%.
期刊介绍：
The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
