Abstract: In this paper the effect of the aggregate content on drying
shrinkage microcracking in cement-based composites is
investigated. Experiments were performed on cement-based
composites containing spherical glass particles as aggregates. It
was found that the use of these model particles is an excellent
tool to study the basic mechanisms of drying shrinkage
microcracking in cement-based composites. The microcracks
were made visible by means of an impregnation technique in
combination with optical microscopy. Crack-patterns were
quantified by using image analysis software. The effect of
aggregate size and quantity on the defined crack-parameters is
reported in this paper. Cracking was recorded on two stages of
drying, which allowed to elucidate the long-term evolution of
drying shrinkage microcracking.
