This document describes two equivalent test methods for determining the glass content in Granulated blast furnace Slag (GBS) as constituent for common cement as defined on EN 197-1.
Method A - Method of determining the glass content of GBS by X-ray diffraction.
Method B - Method of determining the glass content of GBS by polarized optical microscopy.
The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass.
It is usually expressed as a percentage (wt%) of the total slag.
In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.

This document describes a method for the determination of whiteness and the colour of common cements and clinkers.
This method can be used to determine the whiteness of white cements defined in the EN 197-1.
This document does not apply to colour measurements on cement-based formulated products or cement-based products.
The method is based on the measurement of the CIE XYZ trichromatic coordinates and describes the mathematical procedure for converting these coordinates into the CIE 1976 (L*a*b*) colour space.
NOTE Although the possible values of the L* parameter range from 0 to 100, this document applies to the range between 70 and 100 (photopic vision).

This document describes the method for determining the contribution of cement’s alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack.
The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blast furnace slag, or limestone) [1].
This test method can be used in the framework of preventing the risk of alkali silica reaction [2].

This document specifies the equipment to be used, the procedures to be applied and the requirements for sampling common cement and/or its constituent materials, representative of defined lots, for testing purposes.
The same equipment and procedures can be used for other types of cement or materials; in some cases, modifications to the procedure are also permitted, provided that this document and/or the modifications are referenced in the relevant product standards.
The provisions of this document are only applicable when samples of constituent of common cement are:
a) required for evaluating the conformity of common cement or constituent of cement at the characteristics related to common cement, to cement constituents, to the release of dangerous substances to soil and ground water of common cement, and to environmental sustainability of common cement; or
b) requested for checking a delivery or a lot with a standard, the provisions of a contract or the specification in an order.
This document is applicable to the sampling of powders or bulk materials, whether they are:
c) contained in silos;
d) contained in bags, canisters, drums or any other packages;
e) transported in bulk in road vehicles, railway wagons, ships, etc.
NOTE The requirements of this document can also, by agreement between the parties, be followed for acceptance inspections for all non-standardized hydraulic binders.
