Mass concrete is defined in ACI 116R as “any volume of concrete with dimensions large enough to require that measures be taken to cope with generation of heat from hydration of the cement and attendant volume change to minimize cracking.”
ACI 207.1, Guide to Mass Concrete, is the primary resource for guidance in the use of mass concrete for structural building elements. Most of the data and concerns related to the use of mass concrete were formulated from lessons learned during the United States golden era of dam construction.
Although this guide mainly focuses on guidance for traditional mass concrete, much of the information can also be applicable to thermally controlled concrete. The design of traditional mass concrete structures, such as dams, is generally based on durability, economy, and thermal requirements.
Standard Specifications for Concrete Structures (JSCE-SSCS), which show the model for plan, design, execution, maintenance and repair of concrete structures, have been highly recognized in practice and contributed to the development of concrete technology in Japan since its first publication as “Standard
This document contains a history of the development of mass concrete practice and discussion of materials and concrete mixture proportioning, properties, construction methods, and equipment.
