Mass Concrete - design and construction aspects - Structural Guide

WebThe most important component of these types of concrete is the mix design as there are many factors to be incorporated and need to be considered. Some of the key factors considered in the mix design are as follows. Low strength requirements. Use of low cement content. Development of compressive strength by 56-90 days. Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change to minimize cracking." As interior temperature of mass concrete rises due to the process of cement hydration, the outer concrete may be cooling and contracting. If the temperature differs too much within the structure… irc home office
