This study investigates the effect of pozzolana and quick lime as stabilizer materials on expansive soil properties. Disturbed sample was collected from Al-Qadarif city in east Sudan. The basic properties, swelling strength were measured. shows very weak high potential. Mineralogical analysis tests conducted to using XRD tests. contains significant amount montmorillonite mineral (86%). Laborato...

We deal with the textural aspects, porometry and hydric behaviour of combinations of building materials and their durability under attack by salt crystallisation and freezing. We selected 4 types of lime mortar (pure lime mortar, lime mortar + air-entraining agent, lime mortar + pozzolana and lime mortar + air-entraining agent + pozzolana) which were used in combination with either brick or cal...

A common decay scenario in old and new buildings was simulated: the effects on masonry structures of salt efflorescence or subefflorescence produced by the rise of saline solution. Eight different types of masonry wall each made up of a combination of different construction materials (brick, calcarenite and four types of mortar were combined as follows: pure lime mortar, mortar + air entraining...
