Overview

EN 196-5:2011 - Methods of testing cement: Part 5 - Pozzolanicity test for pozzolanic cement (CEN) specifies the reference laboratory procedure for measuring pozzolanicity of pozzolanic cements conforming to EN 197-1. The standard defines how to prepare test samples, the reagents and apparatus to be used, standardization of titrants, the test procedure and interpretation. It excludes Portland pozzolana cements and raw pozzolanas.

Key topics and technical requirements

  • Scope and status: Reference method for pozzolanic cements; aligns with EN 197-1 requirements.
  • Sample preparation: Laboratory sample taken per EN 196-7; representative portion sieved (125 µm or 150 µm), ground and homogenized before testing.
  • Test principle: Compare calcium ion concentration (expressed as CaO) in the aqueous phase in contact with hydrated cement after a fixed period with the calcium concentration that would saturate a solution of the same alkalinity. A lower measured CaO than saturation indicates a positive pozzolanic reaction.
  • Typical test conditions: Example condition in the standard - 20.00 g cement in 100 ml water at 40 °C reaches equilibrium in 8–15 days; if positive at 8 days, continuation is unnecessary.
  • Reagents and titrations: Analytical-grade reagents; EDTA titration for Ca standardization (approx. 0.03 mol/l) and 0.1 mol/l HCl standardized against Na2CO3. Optional visual (Calcon, Patton & Reeders, murexide) or photometric end-point determinations (absorbance at 520 nm or 620 nm).
  • Apparatus & accuracy: Thermostatic enclosure at (40 ± 1) °C, pH meter (±0.05), balance (±0.0005 g), spectrophotometric titration setup, class A pipettes and burettes.
  • Quality control: Requirements for repeatability, reproducibility, expression of results, and reporting; single or duplicate tests depending on statistical control or dispute.

Applications and users

  • Cement manufacturers performing quality control and product certification for pozzolanic cements.
  • Independent testing laboratories and notified bodies verifying compliance with EN 197-1.
  • Research and development teams evaluating new pozzolanic additives or optimizing cement blends for durability, performance and sustainability.
  • Regulatory authorities and procurement bodies requiring standardized proof of pozzolanic activity.

Related standards

  • EN 197-1 (cement composition and conformity) - material scope reference.
  • EN 196 series (general cement test methods), notably EN 196-1, EN 196-2 and EN 196-7, which cover strength, chemical analysis and sampling/preparation referenced by EN 196-5.
