An in-depth analysis of the theoretical background of reactive mechanical impedance measurement and results of laboratory and field tests on compressive strength estimation of concrete.

The study, which was published in the journal Nature Scientific Reports, examined the use of biochar — carbon-rich ...

Unfortunately, it’s impossible to predict the unidirectional compressive strength of composites based on fiber and matrix properties, even when tensile strength is known. Thus, compression testing ...

However, measuring concrete compressive strength in-situ can be challenging. Coring, which involves cutting cylinders of concrete from the final structure and measuring their strength using a ...

When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the in ...

The first parameter, compressive strength, must be equal to or greater than 4,500 pounds per square inch. Thorough consolidation, the second parameter, means that concrete must be embedded around ...

Nevertheless, particular test standards which govern the concrete industry need strain rate feedback that cannot be attained with manual operation. For a portion of concrete tests, it is necessary to ...

Can flexure testing provide estimates of composite strength properties? Flexure tests are simple to perform, yet the state of stress and failure modes are among the most complex.
