Abstract

The paper describes the particular and unknown constructive technique employed for Shali, an ancient fortress dating back to the XII century sited on a hill of the oasis of Siwa in the western Egyptian desert. The masonries are realised with salt blocks, taken from the nearby salty lakes connected by an abundant mud mortar very rich in salt. The drying process of the mixture (particularly of the mud with the role of mortar) obtains an immediate joint with the salt “stone” pieces because of the crystallization process. The result is a sort of conglomerate. Such a technique is the result of the capability and skill of man to take advantage of the local environmental resources and at the same time makes it possible to realise particularly comfortable buildings in the severe climatic condition of the oasis. In order to understand the building technology, the behaviour and the decay phenomena observed in the masonries, building materials from old masonries and ancient quarries have been characterised from the compositional and mechanical point of view. The first results of this research are offered in the paper.
