Both ASTM and EN specifications require specimen curing by leaving the moulds for the first 16 hours up to a maximum of three days, protected against shock, vibration and dehydration at a temperature from 20 ± 5°C or 25 ± 5°C in hot climates (EN method) and 16 to 27°C (ASTM method). After the removal from their molds, specimens need to be stored in moist conditions at 20 ± 2°C (EN) or 23 ± 1.7°C (ASTM) with a relative humidity ≥ 90%. Alternatively, they can be cured in water at the same temperature.
