AbstractAfter tests were carried out on flues and chimneys at the Champs-sur-Marne Experimental Station, certain principles were established for improving the manufacture of lightweight concrete flue units. At the same time, simple apparatus was developed for carrying out rapid heat- resistance tests on flue units. The article includes a description of the research and the conclusions which can be drawn from it, and deals with the permeability to air, expansion and heat resistance of flue and chimney units, and the way in which the simplified heat resistance testing apparatus is used. This article also includes details of some of the first results of tests which were carried out at the C.S.T.B. Experimental Station in order to establish the effect of the various parameters involved in the manufacture of concrete on its behaviour when subjected to heat.
