MIXTURE PROPORTIONING FOR DURABLE CONCRETE: CHALLENGES AND CHANGES

Numerous changes and innovations have occurred in concrete materials and technology during last century. These changes have provided engineers with many advantages in the design and construction of concrete structures. Concurrently, however, the application of the new developments and changes in concrete mixture proportions have also generated new durability problems. This article addresses concerns surrounding the mixture proportioning of concrete and discusses a variety of related topics including extended service life requirements of modern concrete, advancements in concrete technology (portland cements, ready-mix concrete, air-entraining agents, high-strength concrete and admixtures), recent research (permeability, microcracking, early-age cracking), and recommendations for enhanced durability through better mixture proportioning.
