Abstract
A novel design approach of an impact testing apparatus for concrete and highperformance
cementitious composite specimens is described in this paper. To
date, various approaches have been adopted when measuring the behaviour of
concrete under impact loading. Most of the research teams used machines based
on a guided drop-weight falling down freely on a concrete specimen. This paper
describes the development process of a novel machine that is based on the
pendulum principle. This experimental setup allows a horizontal placement of a
specimen which has several advantages, such as easy elimination of a so called
double hit, easy access to the sample and free space for the sensor mounting. The
machine in the current setup is used for testing beam specimens, but, due to its
modular concept it is also possible to rearrange the setup to test slabs utilizing a
proprietary load transformer. The preliminary experimental results are shown in
this paper as well as a description of the data acquisition system and adopted
method of data filtration.
Keywords: impact, horizontal loading, concrete, filtration.
