Influence of pore connectivity on the spalling behaviour of mortars

Experimental research into the spalling behaviour of mortars and if it is possible to predict the spalling resistance. Research is divided into spalling experiments with varying parameters and experiments to analyse and characterize the pore structure. By combining both results, a first step is taken into a formula that is able to predict the...

Determination of aggregate shapes using X-ray computed tomography and making virtual concrete

The shape of aggregates has significant effect on the concrete properties. To predict these properties with computational models the mathematically characterized shape has to be known. In the past, scientists assumed simple shapes like spheres and ellipsoids. To make models more realistic, aggregate shapes has to be also more realistic. X-ray...
