Tests for mechanical and physical properties of aggregates - Part 10: Determination of water suction height

This European Standard describes the reference method, used for type testing and in case of dispute, for determining the water suction height of an aggregate in direct contact with a free water surface. For other purposes, in particular production control, other methods may be used, provided that an appropriate working relationship with the reference methods has been established.
NOTE   Capillary water uptake in an aggregate layer under the ground floor may cause moisture problems in the building. If the layer is thicker than the water suction height of the aggregate used, the layer is considered as a capillary barrier.

Prühfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 10: Bestimmung der Wassersaughöhe

Diese Europäische Norm beschreibt ein Referenzverfahren für die Bestimmung der Wassersaughöhe von Gesteinskörnungen, die direkten Kontakt zu einer freien Wasseroberfläche haben, welches zur Anwendung für die Typprüfung und im Streitfall vorgesehen ist. Für sonstige Zwecke, insbesondere für die werkseigene Produktionskontrolle, dürfen andere Verfahren angewendet werden, unter der Voraussetzung, dass eine angemessene funktionierende Beziehung zu den Referenzverfahren hergestellt wurde.
ANMERKUNG   Die kapillare Wasseraufnahme in einer Gesteinskörnungsschicht unter dem Erdgeschoss kann zu Feuchteproblemen im Gebäude führen. Ist die Schicht dicker als die Wassersaughöhe der verwendeten Gesteinskörnung, wird die Schicht als Kapillarsperre angesehen.

Essais pour déterminer les caractéristiques mécaniques et physiques des granulats - Partie 10 : Hauteur de succion d’eau

La présente Norme européenne décrit la méthode de référence, destinée à être utilisée pour des essais de type ou en cas de litige, pour la détermination de la hauteur de succion d’eau d'un granulat en contact direct avec la surface libre d'une couche d'eau. Pour d'autres besoins, en particulier le contrôle de la production, d'autres méthodes peuvent être utilisées, à condition d'établir une relation de fonctionnement appropriée entre ces dernières et la méthode de référence.
NOTE   La montée d'eau par capillarité au travers d'une couche de granulat située sous la dalle de sol risque de causer des problèmes d’humidité dans le bâtiment. Si l'épaisseur de la couche est supérieure à la hauteur de succion d’eau du granulat utilisé, la couche est considérée comme une barrière anti-capillarité.

Preskusi mehanskih in fizikalnih lastnosti agregatov - 10. del: Določevanje kapilarnega dviga vode

Standard EN 1097-10 določa referenčno metodo, ki se uporablja za tipsko preskušanje, in v primeru spora za določevanje kapilarnega dviga vode agregata v neposrednem stiku s prosto površino vode. Za druge namene, zlasti za kontrolo proizvodnje, se lahko uporabijo druge metode, če obstaja primerna delovna povezava z referenčno metodo.

Overview

EN 1097-10:2014 - Tests for mechanical and physical properties of aggregates - Part 10 provides the reference method for determining the water suction height of aggregates in direct contact with a free water surface. Published by CEN, this method is intended for type testing and as the authoritative procedure in case of dispute. For routine production control, alternate methods may be used only when an appropriate relationship to this reference method has been established.

Why it matters: capillary water uptake in aggregate layers under ground floors can cause moisture problems. If an aggregate layer is thicker than its water suction height, it functions as a capillary barrier, reducing rising damp risk.

Key topics and technical requirements

• Scope: Reference method for water suction height; hygroscopic moisture and compacted dry bulk density are also measured and recorded.
• Test principle: A dry aggregate test portion in a vertical transparent tube is placed in contact with water. Water rises by capillarity; equilibrium moisture distribution defines the suction height.
• Measured parameters:
  • Maximal hygroscopic moisture content (in sealed container near 100% RH)
  • Compacted dry bulk density (by layer filling and light compaction)
  • Capillary water uptake over time and derived water suction height
• Apparatus & environment: transparent tube and vessel (minimum dimensions depend on aggregate size), moisture container with saturated K2SO4 solution, ventilated oven at (110 ± 5) °C, test cabinet maintained ~20–25 °C (±2 °C).
• Sampling & preparation: Laboratory sample reduced per EN 932-2; specified minimum test portion volumes; oven-dry to constant mass (EN 1097-5).
• Test progression: initial 5 min mass, then measurements at 24 h, 48 h, 72 h, 168 h and weekly until mass change over 7 days is < 0.2 kg/m² of suction area.
• Reporting: mandatory data include suction height, hygroscopic moisture, compacted dry bulk density and test conditions.

Applications and users

• Who uses it: aggregate manufacturers, independent testing laboratories, QA/QC engineers, consultants, structural and civil engineers, flooring and foundation designers, building regulators and contractors.
• Practical uses:
  • Establishing whether an aggregate layer will act as a capillary barrier beneath ground floors
  • Type testing for product specifications and conformity assessments
  • Resolving contractual disputes about moisture performance
  • Supporting material selection for drainage, sub-base and floor construction

Related standards

• EN 932 series (sample reduction, general properties)
• EN 1097 series (other mechanical/physical aggregate tests)
• EN 1097-5 (water content by oven drying)
