CHANGES IN CEMENT PROPERTIES AND THEIR EFFECTS ON CONCRETE. REPORT OF A CONCRETE SOCIETY WORKING PARTY

The report presents the findings of a working party set up to quantify the effects of changes that have taken place in the properties of manufactured cements, and to assess the effects of such changes on concrete properties and durability. Conclusions show that: 1) the total proportion of silicates and other compounds has remained at about the same level but the ratio of tricalcium silicate/dicalcium silicate has increased; 2) there has been no significant change in cement fineness; 3) there has been a marked increase in the strength of concrete; 4) such strength increases are likely to affect mix designs by allowing lower cement contents and increased water/cement ratios; 5) the changes have serious implications for reducing the durability of concrete; and 6) concrete should be specified to meet not only design strength but also environmental durability requirements. A number of recommendations are made concerning the conclusions reached. (TRRL)
