BRIEF HISTORY
The IS0 Recommendation R 597, Definitions and Terminology of Cements, was drawn
up by Technical Committee ISO/TC 74, Hydraulic Binders, the Secretariat of which is
held by the Institut Belge de Normalisation (IBN).
Work on this question by the Technical Committee began in 1952 and led, in 1962,
to the adoption of a Draft IS0 Recommendation.
In January 1965, this Draft IS0 Recommendation (No. 771) was circulated to ali the
IS0 Member Bodies for enquiry. It was approved, subject to a few modiikations of an
editorial nature, by the following Member Bodies :
Argentina Ireland Romania
Australia Israel Spain
Austria Italy Sweden
Belgium Japan Turkey
Czechoslovakia Korea, Rep. of U.A.R.
Denmark Netherlands United Kingdom
France New Zealand U.S.A.
Poland U. S. S.R.
Hungary
India Portugal Yugoslavia
Two Member Bodies opposed the approval of the Draft:
Germany
Norway
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in August 1967, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 597 August 1967
DEFINITIONS AND TERMINOLOGY OF CEMENTS
1. SCOPE
This IS0 Recommendation lays down the general definitions applicable to cements, as well as
the particular definitions and the denominations which pertain to each type of cement.
L
2. GENERAL DEFINITIONS
2.1 Cement
Finely ground material forming, by the addition of an appropriate quantity of water, a more
or less liquid binding paste, capable of hardening both under water and in air and of binding
together appropriate material. The compositions and denominations should be in con-
formity with the present IS0 Recommendation.
2.2 Principal component materials
L
2.2.1 Properties of principal component materials. The principal materials used in the manu-
facture of cement have either hydraulic or pozzolanic properties.
Hydraulic properties. The ability of a material to set and harden in the presence of
water, with formation of stable compounds.
Pozzolanic properties. The ability of a material to combine with lime at ambient tem-
perature and in the presence of water in order to produce compounds having hydraulic
properties.
2.2.2 Portland clinker. A product consisting mostly of calcium silicates which is obtained by
heating to partial fusion a predetermined and homogeneous mixture >f materials
principally containing lime (Cao) and silica (SiOJ with a smaller proportion of alumina
(A1,OJ and iron oxide (Fe,O,).

2.2.3 Blastfurnace slag. The granulated product obtained by suddenly cooling (quenching)
of iron ore in a
a melt of suitable chemical composition, resulting from the smelting
blast furnace.
2.2.4 High alumina clinker. A product consisting mainly of calcium aluminates which is
obtained by complete or partial fusion of a predetermined mixture of materials mainly
containing alumina (Al,O,) and lime (Cao) with smaller proportions of iron oxides,
silica (SiOa and other oxi
