ACI uses cement content alone as the basis for allowable chloride limits for new construction.
With the heightened use of SCMs and performance specifications for cement, there is need to evaluate using total cementitious materials content as the basis for allowable chloride limits in new construction and for chloride thresholds.
Looking forward, rational design approaches will be discussed, as well as the current knowledge gaps that must be addressed before such methodologies could be standardized.
A review of current research in fire performance of concrete and masonry will also be reviewed, especially as that research relates to promoting rational design methods.
Effective construction practices are essential to the long-term performance of the concrete pavement structure.
“Guide to a Simplified Design for Reinforced Concrete Buildings,” ACI 314R-16 presents simplified methods and design techniques that facilitate and speed the engineering of low-rise buildings within certain limitations.This session will be useful for researchers, engineers, consultants, and those developing standards and specifications.ACI Subcommittee 440-M, FRP-Repair of Masonry Structures, is sponsoring this technical session focusing on various applications of fiber-reinforced polymer (FRP) systems for masonry structures.The objective of the session is to educate government code officials, licensed design professionals, owners, and contractors on the applicability and use of ACI 562-13, “Code Requirements for Evaluation, Repair, and Rehabilitation of Concrete Buildings and Commentary,” and the new ACI/ICRI “Guide to the Code for Evaluation, Repair, and Rehabilitation of Concrete Buildings” through practical examples.This session will explore whether ground limestone and mineral filler should be considered inert fillers or considered to contribute to hydration, strength, economy, and sustainability of concrete mixtures.Early-Age Concrete Properties Measurements for Concrete Pavement Construction Operations and Traffic Opening (ACI Fall 2016 Convention, Philadelphia, PA) This session will promote best practices for obtaining the early-age concrete properties desirable for good concrete pavement performance based on reliable measurements instead of empirical evaluation, guessing estimates, or personnel experience.
