The Behavior of Non-Destructive Test for Different Grade of Concrete

, 2020
Rebound hammer are prefer as non-destructive testing methods; where compression test as destructive test. A general series of tests for rebound hammer and destructive test was carried out at heavy concrete laboratory to obtain the desire result. A set of

Experimental determination of the initial compressive strength of concrete using a rebound test hammer

IOP Conference Series: Materials Science and Engineering, 2018
This paper deals with rebound hammer testing of concrete in the early stage of ageing. Six types of concrete were produced for the purpose of the presented experiment and differed in the water/cement ratio and were otherwise identical as to the input components.

Policy Networks and Policy Entrepreneurship in the EU: Explaining Structural Policy Change in Pharmaceutical Innovation Incentives and Health Technology Assessment

European Policy Analysis, EarlyView.
ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...

Uniaxial Compressive Strength of Antarctic Peninsula Rocks: Schmidt Hammer Rebound Test

Sains Malaysiana, 2017
The uniaxial compressive strength test is a destructive and time consuming test. A number of non-destructive methods using portable testing equipment are more applicable and easier to conduct. This paper presents the results of a systematic approach to determine the uniaxial compressive strength of rock material using the Schmidt hammer rebound test. A
