Overview - EN 196-1:2016 (Methods of testing cement - Determination of strength)

EN 196-1:2016 is the CEN standard that defines the reference method for determining the compressive and (optionally) flexural strength of cement mortar. It specifies the mortar composition, specimen geometry, laboratory conditions, reference equipment and procedures used to assess whether cement strength conforms to its specification. The method is applicable to common cements and other cements or materials when their product standards call up EN 196-1. It is not suitable for some special cements (for example, those with very short initial setting times).

Key topics and technical requirements

  • Specimen geometry and mix: Prismatic specimens 40 × 40 × 160 mm cast from mortar with a binder : sand : water mass ratio of 1 : 3 : 0.5 (water/cement = 0.50) using CEN Standard sand or validated equivalent.
  • Reference equipment:
    • Mechanical mixer (stainless steel bowl ≈ 5 L, planetary blade; specified gap 3 ± 1 mm; defined low/high speeds).
    • Steel moulds with three compartments for 160 mm prisms, hardened internal faces.
    • Jolting compaction apparatus (reference method) - alternative compaction and vibration tables permitted only after validation.
    • Flexural and compressive strength testing machines calibrated per ISO/EN requirements.
    • Test sieves to ISO 3310-1 / ISO 565 series.
  • Laboratory conditions and curing:

28 d ± 8 h. 9 Testing procedures 9.1 Flexural strength Use the three-point loading method with one of the types of apparatus described in 4.7. Place the prism in the apparatus (4.7) with one side face on the supporting rollers and with its longitudinal axis normal to the supports. Apply the load vertically by means of the loading roller to the opposite side face of the prism and increase it smoothly at the rate of (50 ± 10) N/s until fracture. Keep the prism halves covered with a damp cloth until tested in compression. Calculate the flexural strength, Rf, in megapascals from: ××ff31,5
lF = Rb (1) where Rf is the flexural strength, in megapascals; b is the side of the square section of the prism, in millimetres; Ff is the load applied to the middle of the prism at fracture, in newtons; l is the distance between the supports, in millimetres. 9.2 Compressive strength Carry out the test on halves of the prism broken either as described in 9.1 or by using suitable means which do not subject the prism halves to harmful stresses. Test each prism half by loading its side faces using the equipment described in 4.8 and 4.9. Centre the prism halves laterally to the platens of the machine within ± 0,5 mm, and longitudinally such that the end face of the prism overhangs the platens or auxiliary plates by about 10 mm.
