Abstract

The effect of particulate matter - as a component of an internal combustion engine's exhaust gas - on 8 different types of construction materials have been studied under laboratory conditions. Our aim was double. On the one hand it was to investigate the degree of discolouration, whether there is a difference between the 8 types of rock in the same exposure, after laboratory contamination. On the other hand to measure the mass effect of particulate on the rocks. For testing the adverse effects of diesel soot and particulate matter on stones a small scale laboratory exposure chamber was constructed and built in the exhaust system of the engine. A compression ignition engine was used to pollute directly the set of stones. Mass and colour measurement tests have been carried out on the stones before and after the exposure. The result is as expected small difference in the mass properties and a greater changes in terms of colour measurement.
