Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

This study investigates the mechanical behavior of alkali-activated concrete (AAC) subjected to triaxial compression under different confining pressures and freeze-thaw cycles. A series of triaxial ...

Concrete compressive strength testing is crucial for construction quality control. The traditional methods are both time-consuming and labor-intensive, while machine learning has been proven effective ...

The use of the non-destructive testing methods for determining the compressive strength of high performance concrete ensures high quality. Compressive strength test results are mainly used to ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

In the global construction quality assurance and materials testing industry, Zhuozhou Tianpeng Imp. and Exp. Trade Co., Ltd. has emerged as a top concrete testing equipment manufacturer, recognized ...
