Abstract

This European Standard specifies a method for determining the water retentivity of freshly mixed mortars (in the following referred to as fresh mortars) containing mineral binders and normal, as well as light weight aggregates, when subjected to suction.  This method applies to masonry mortars, rendering mortars and plastering mortars.

Overview

prEN 1015-8 - Methods of test for mortar for masonry - Part 8: Determination of water retentivity of fresh mortar is a CEN draft European Standard that specifies a laboratory method to measure the ability of freshly mixed mortars to retain water when subjected to suction. The scope covers mortars containing mineral binders and both normal and lightweight aggregates, and applies to masonry mortars, rendering mortars and plastering mortars.

Key topics and requirements

  • Purpose: Determine the water retentivity of fresh mortar under suction to assess suitability for adhesion, workability and curing on absorbent substrates.
  • Materials covered: Fresh mortars with mineral binders and normal or lightweight aggregates.
  • Test focus: Behaviour of the fresh mortar when subjected to suction (i.e., the capacity to resist water loss to substrates or suction plates).
  • Standardization elements:
    • Defined scope and applicable mortar types.
    • Controlled sampling and specimen preparation to ensure repeatable results.
    • A reproducible test procedure to quantify water retention for comparative and quality-control use.
    • Reporting of results in standardized form so formulations, batches and workmanship can be compared.

Note: prEN 1015-8 defines the method concept and the parameters to be measured; it does not replace project-specific requirements or on-site workmanship controls.

Applications

  • Quality control in mortar production - manufacturers can use the method to verify that fresh mortar batches meet water-retentivity expectations before shipment.
  • Product development and formulation - R&D teams use water-retentivity data to optimize binder, admixture and aggregate ratios for desired application (masonry, rendering, plastering).
  • Construction specification and conformity assessment - specifiers and testing laboratories use the standard to assess compliance with performance requirements and to reduce risk of poor adhesion or premature drying on absorbent backgrounds.
  • Site troubleshooting - contractors and technical advisors use water-retentivity results to diagnose issues related to suction, workability and setting on different substrates.

Who uses this standard

  • Mortar and cementitious product manufacturers
  • Independent testing laboratories and certification bodies
  • Construction materials R&D teams
  • Contractors, specifiers and quality managers in masonry, plastering and rendering trades

Related standards

  • prEN 1015 series - Methods of test for mortar for masonry (other parts cover sampling, consistency, strength and durability tests).
  • prEN 1015-9 (referenced in related documents) - Determination of service life of fresh mortar.
