EDITORIAL
THE 7th INTERNATIONAL CONGRESSON THE CHEMISTRY OF CEMENT TO BE HELD IN 1980 IN PARIS The First International Congress on the Chemistry of Cement was held in London in 1918. I t was not until 20 years l a t e r that the next Congress of this nature was convened in Stockholm in 1938. Although provisions had been made to arrange Congresses every 8 years, the next was delayed due to the Second World War and was not held until 1952 in London. The fourth took place in Washington and Skokie in 1960, and the f i f t h in Tokyo in 1968. With a reduction of the periodicity of the symposia to six years, the Sixth International Congress on the Chemistry of Cement was held in Moscow in 1974. The Seventh Congress on the Chemistry of Cement w i l l be held at Palais des Congres in Paris on Monday, June 30 through Friday, July 4, 1980. tific
The themes of the Congress have been selected by the International ScienCommittee. The themes and sub-themes are as follows:
Theme I: Influence of raw materials, fuels and manufacturing processes on clinker structure and phoperties. Leader: M. Peter (Switzerland). Sub-themes: I . I ) Influence of the nature and preparation of raw materials on the r e a c t i v i t y of raw mix; 1.2) Influence of thermal treatment of raw mix; 1.3) Kinetics of clinker formation. Structures and composition of clinker and its phases; 1.4) Influence of grinding and type of clinker storage. Theme 2: Hydration of pure Portland cements. Leader: F. Locher (GFR). Sub-themes: 2.1) Hydration mechanisms; 2.2) Hydrate structure and composition. Theme 3: Structure of slags and hydration of slag cements. Leader: M. von Euw (France). Sub-themes: 3.1) Slag structure and i d e n t i f i c a t i o n of slags; 3.2) Hydration mechanism of slag cements. Hydrate structure and behavior. Theme 4: Structure of pozzolana and fly-ash and hydration of pozzolanic and fly-ash cements. Leader: F. Massazza ( I t a l y ) . Sub-themes: 4.1) Structure and i d e n t i f i c a t i o n of pozzolana and fly-ash; 4.2) Hydration mechanism of pozzolanic and fly-ash cements. Hydrate structure and behavior. Theme 5: Special cement. Leader: F. de Assis Basilio (Brazil). Sub-themes: 5.1) Aluminous cements; 5.2) Expansive cements; 5.3) Other cements. Theme 6: Cement pastes: rheology, evolution of properties and structures. Sub-themes: 6.1) Structure and mechanical properties of hydrates; 6.2) Rheology; 6.3) Mathematical models for forecasting cement paste properties. Theme 7: Interface reactions between cement and aggregate in concrete and mortar. Leader: G. Idorn (Denmark). Sub-themes: 7.1) Bond strength; 7.2) Durability.

In connection with the Congress, four seminars will be attended by experts invited by the Scientific Committee: A) Role of C3A in the hydration process of cements and its interaction with sulfates. B) Fixation of industrial wastes by hydraulic binders. C) Energy savings - prospective outlook. D) Influence of cement characteristics on concrete performance.

RECENT (CCR).JOURNA~ CHANGES We are pleased with the steady input of interesting papers on an increasing breadth of subjects. The inevitable accompaniment is the fact that we continue to receive more papers than we can publish, and must steadily find ways to res t r i c t the volume of pages printed.
