Standard Sand CEN EN 196-9
Hydration heat measure of cements semi-adiabatic method
USAGE
This sand is used for the measurement of the hydration heat of cements by semi-adiabetic calorimetry according to the Langavant method.
TECHNICAL CHARACTERISTICS
The CEN standard sand (ISO standard sand) is a natural and siliceous sand (silica > 98%)
The grains are round-shaped. The sand is washed, dried, sieved and prepared in a modern workshop offering all guarantees of quality and regularity.
The sand is packaged in polyethylene bags, each containing 1 080 +/- 1 g.
CONTROLS
The particle size composition is determined by sieving complies with the requirements of standards EN 196-1 (§ 5) and ISO 679: 2009 (§ 5).
Square mesh size (mm) | Cumulative (%) retained |
|---|---|
0.08 | 99 ± 1 |
0.16 | 87 ± 5 |
0.50 | 67 ± 5 |
1.00 | 33 ± 5 |
1.60 | 7 ± 5 |
2.00 | 0 |
The other controls are bag weight, humidity level measurements and mechanical strength checks, according to the requirements of standards EN 196-1 (§ 11) and ISO 679: 2009 (§ 11).
CONFORMITY
Compliance with the standard is checked by the L.E.M.V.P. (Laboratoire d’Essais des Matériaux de la Ville de Paris), 15 rue Jean Baptiste Berlier 75013 PARIS.
The certificate of compliance to the European standard is issued by AFNOR (Association Française de Normalisation), 11 Rue Francis de Pressensé – 93571 La Plaine Saint Denis Cedex.
