ACI 207.1R-05 (R2012) PDF Download

The ACI 207.1R-05 (R2012) standard provides guidance on the design considerations, materials, construction methods, and equipment used in mass concrete structures. Mass concrete refers to any concrete volume that is large enough to experience significant heat generation from hydration and subsequent volume change, which can lead to cracking. The focus of this standard is on durability, economy, and thermal action, with strength being of secondary concern.

The document includes a historical overview of the development of mass concrete practice, highlighting the evolution of best practices over time. It also covers various aspects related to materials and concrete mixture proportioning, discussing the choices that need to be made to achieve desired properties. Construction methods and techniques for placing and consolidating mass concrete are described in detail, providing practical guidance for ensuring the integrity of the structure.

It is important to note that the scope of this standard does not include roller-compacted concrete, which is a separate concrete placement method commonly used in large-scale construction projects. ACI 207.1R-05 (R2012) serves as a valuable resource for engineers, architects, and contractors involved in the design and construction of mass concrete structures, offering comprehensive guidance on key considerations to ensure the successful implementation of these projects.
