Robert W. Cannon* Chairman. Reported y ACI bCommittee RACI COMMITTEE REPORT Chapter 6—Quality control of RCC, p. Although this guide mainly focuses on guidance for traditional mass concrete, much of the information can also be applicable to thermally controlled concrete. Robert F. Oury Fred A. Anderson Howard L. Boggs. Reported by ACI Committee James L. Cope. Construction ACI R Report on Thermal and Volume Change Effects of Cracking of Mass Concrete Author: ACI Committee Subject: This report presents a discussion of the R Cooling and Insulating Systems for Mass Concrete. The design of traditional mass concrete structures, such as dams, is generally based on durability, economy, and thermal requirements ements and structures are discussed in ACI R. Cooling and insulating systems for mass concrete are addressed in ACI R. Mixture proportioning for mass concrete is dis-cussed in ACI —History —When concrete was first used in dams, the dams were small and the concrete was mixed by hand. It covers traditionally placed and consolidated mass concrete and does not cover roller-compacted concrete Although this guide mainly focuses on guidance for traditional mass concrete, much of the information can also be applicable to thermally controlled concrete.
