Hot Weather Concreting NoteAs a general rule, each 10o F increase in ambient temperature reduces slump about 1". A 30o F increase in mix temperature can cut setting time in half, increase water requirements, and reduce the 28-day compressive strength as much as 25%. A switch from ASTM C494 Type A to Type D water reducing and set retarding mix may be part of an effective plan for hot-weather concreting.
