Comparison of measurements in standards for the properties of pozzolanic materials.

Property	EN 13263	ASTM C 1240
Reference mix	225 g of distilled water 1350 g of standard sand 450 g of test cement	242 g of distilled water 1375 g of standard sand 500 g of test cement and X g of Flow agent (superplasticizer)
Pozzolanic (by replacement)	45 g	50 g
Superplasticizer (Flowability determined using specific equipment)	Superplasticizer is inappropriate with EN-934-2. As much superplasticizer as necessary to determine the standard flow (±5 mm).	Dry high range water reducer in conformity with C494 Type F. Adding superplasticizer to gain a flow mixture of 100–115% (summation of 4 measurements which done with a special caliper).
Curing (after 24 h in the mold)	Submerged in 20 ± 1 °C water temperature for 27 days.	In airtight glass containers at temperature of 65 ± 2 °C for 6 days.
