    Rationale

    ASTM C94 includes maximum temperature limit for concrete in the section on hot weather. This revision responds to negatives and comments on C09 LB 20-04 to revise section 12.12 to comply with temperature limit stated by the purchaser. The note refers the user for to temperature limits in ACI specifications and indicates there may be other entities that specify different limits. The Note also deletes the general statement that difficulties may be encountered, because it is not considered useful and can be said of any factor when producing and delivering concrete.
