    Since cement gains strength over time the time at which strength test is to be conducted must be specified. Typically times are 1 day (for high early strength cement) 3 days 7 days 28 days and 90 days (for low heat of hydration cement). Also it should be noted that cement-mortar strength is not directly related to concrete strength.
