At CMC we have the equipment and expertise to satisfy the full range of petrological requirements in the construction industry.
Our staff are skilled in stereo-microscopy, transmitted and reflected polarised light microscopy and electron microscopy.
The petrological work is closely linked with our mineralogical and chemical services to provide an integrated approach to our clients requirements and as part of an investigation.
A common concern in the evaluation of bridge and other concrete structures in which potentially reactive aggregates were included is whether the aggregates have reacted with the alkali from the cement to produce an expansive gel. Petrography is the definitive method of identifying Alkali Silica Reaction (ASR) and whether it has developed to a disruptive stage.
