Abstract:
Concrete mixed, transported, and placed under conditions of high temperature, low humidity, or wind, requires an understanding of the effects such environmental factors have on concrete properties and construction operations. When these factors are understood, measures can be taken to eliminate or minimize undesirable effects. This recommended practice defines hot weather, lists possible unfavorable effects and recommends practices intended to minimize +hem. Among these recommendations are such important measures as precooling ingredients, limitations of concrete temperature as placed, length of haul, facilities for handling concrete at the site, and special placing and curing techniques. A selected bibliography is appended.
