Determination of compressive strength of concrete in prefabricated units using NDT methods and advanced regression diagnostics
Uchytilová, Jitka ; Kocáb, Dalibor (referee) ; Misák, Petr (advisor)
This thesis deals with the rebound hammer method as a tool for approximation of the time limit for handling the concrete. The theoretical part is focused on three fields of knowledge - rebound hammer test, production of precast concrete components and statistical data analysis. The following practical part deals with the design of two single-parameter linear functions for two types of rebound hammer testers - SilverSchmidt L and SchmidtOriginal N. Statistical data processing is completed by the analysis of influential points by using the Cook’s distance. The resulting statistical models are compared with commonly used relationships.
