Influence of composition of repair Roman cement mortars on their salt weathering susceptibility


Abstract eng:
Salt crystallization is a common cause of decay for mortars used in historical buildings. This paper describes the influence of mortars composition on their salt crystallization resistance. The optimum formulation and application of Roman cement mortars which could produce compatible and durable repairs of the original substrates was studied. The measurements of pore size distribution related to mortars composition, hydric parameters as well as the salt crystallization cycles were performed. The results of the crystallization tests shown that the repair Roman cement mortars with hydric parameters close to those obtained for historic substrates, though different pore size distributions have similar salt crystallization resistance and they are in broad terms compatible with historic masonry or stuccoes. .
