The action of some aggressve solutions on Portland, pozzolanic and blastfurnace slag cement mortars

An account of the results of a systematic investigation on the effects of percolation by solutions of magnesium sulphate and magnesium chloride of the same normality, respectively, through mortar samples manufactured with different types of cement is given by the Authors. The aim of the investigation is the comparative evaluation of the behaviour of the single cements under the attack from the two aggressive solutions, as well as the search for possible relationships between the manifold factors responsible, to a different extent, for the lowering of the mechanical strength of the resultant mortars.
