Monitoring of concrete hydration by electrical measurement methods
Analysis of impedance spectra of inhomogeneous materials is a part of the impedance spectroscopy which is still waiting for its development. Materials having higher electric resistance values (over 500 kohm) can be considered ...
Cast Screws as Shear Anchors for Composite Slabs
Composite slabs consist of trapezoidal steel sheeting and concrete cover. The steel sheeting serves as both, a lost framework and a tension bearing member after hardening of concrete. The longitudinal shear between the ...
Behaviour of cement composites with lightweight and heavyweight aggregates at high temperatures
(Budapest University of Technology and Economics, 2017-03-24)
This paper presents new results of the research of the influence of individual input components done on the behaviour of cement based composite materials exposed to high temperatures. A new approach of this research lies ...
Nondestructive Testing of Advanced Concrete Structure during Lifetime
(Hindawi Publishing Corporation, 2015-07-08)
The paper reports on measurements and analysis of the measurements during hardening and drying of specimens using selected acoustic nondestructive testing techniques. An integrated approach was created for better understanding ...
