Abstract: This study presents a partially nondestructive testing (PDT) method, the innovative double-shear test method (DSTM), to improve the accuracy of concrete strength tests in situ and reduce structural damage. This method ...

Abstract: This study analyzed the impact of freeze–thaw cycles on a 3% NaCl solution and water in recycled concrete, utilizing a rapid freezing method and a water–cement ratio of 0.45. The weight, relative dynamic modulus of elasticity, ...

Abstract: The point-load test method (PLTM) commonly used in the geotechnical area is shown in this paper to estimate the compressive strength of in situ masonry mortar. A specially developed portable PLTM instrument was used for ...
