DURABILITY OF POZZOLANIC CEMENTS AND ITALIAN EXPERIENCE IN MASS CONCRETE. IN: DURABILITY OF CONCRETE. SECOND INTERNATIONAL CONFERENCE. AUGUST 4-9, 1991, MONTREAL, CANADA. VOLUME II

In comparison to portland cements, pozzolanic cements are more resistant to various aggressive agents such as pure and acidic water, chlorides, and sulphates. Furthermore, they can also prevent expansion caused by alkali-aggregate reaction. Provided that concretes having the same strength are compared, carbonation depth of pozzolanic cements is similar to that of portland cements. In Italy, where they have been used extensively for the construction of buildings and civil engineering works, pozzolanic cements accounted for over 15 million tons of cement prodcution in 1989. Direct evidence of the durability of pozzolanic cements is provided by many Italian dams built over forty years ago which - despite heavy and varied environmental conditions - still show good serviceability.
