Chemical properties of building stones need to be con- sidered in conjunction with physical properties in studying processes of deterioration, and they are covered elsewhere in these proceedings. The comprehensive book on properties and durability of stone by Erhard Winkleri has been helpful in preparing this report.

The following properties of the stones should be looked into before selecting them for engineering works: (i) Structure: The structure of the stone may be stratified (layered) or unstratified. Structured stones should be easily dressed and suitable for super structure. Unstratified stones are hard and difficult to dress. They are preferred for the foundation works.

When the cost of quarried stone to cost of finished stone is considered, it will be found that the labour cost is far greater than the price of the stone. Thus, a difference in the price between two alternative stones is unimportant and it would be unwise to reject a more durable stone on the grounds that it was costly.
