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. |
