The influence of various inorganic salts, as chloride admixtures to Portland cement, on the mechanical properties and the durability of the matrix has been studied. The salts used in this study are CrCl(3).6H(2)O, NiCl(2) and CdCl(2). Improved compressive strength values are obtained which have been correlated to the stable metal hydroxide formation in high pH environments. Under static water conditions at 50 C, hydrolised chloride ions exhibit adverse effects on the matrix durability through rapid release of calcium as CaCl(2) in the initial period of leaching. On the other hand, enhanced matrix durability is obtained on long term leaching in the case of cement containing CrCl(3).6H(2)O.
