The American Concrete Institute recently published “ACI 308R-16 Guide to External Curing of Concrete” for concrete industry professionals. This guide reviews and describes practices, procedures, materials and monitoring methods for the external curing of concrete and provides guidance for specifying curing procedures. Current curing techniques are presented and commonly accepted methods, procedures and materials are described. Methods are given for curing structures and buildings, pavements and other slabs-on-ground, and for mass concrete. Curing methods for several specific categories of cement-based products are discussed in this document. New research and methods of curing are presented. The guide also covers definitions, curing methods and materials, curing for different types of construction, and monitoring curing and curing effectiveness. Topics such as internal curing, curing at elevated temperatures, sustainability, curing of moisture-sensitive flooring, sensors for mass concrete curing, and new curing monitoring techniques have been added or enhanced in this document.
