FARMINGTON HILLS, Mich. (March 26, 2010) – The American Concrete Institute (ACI) announces the availability of three new publications to educate and inform industry professionals on the newest concrete-related information and technology.  As always, ACI members receive a special discount (up to 40 percent) on all ACI publications.  Publications can be ordered by calling 248-848-3800 or online at  
Report on Early-Age Cracking: Causes, Measurement and Mitigation (231R-10)
Early-age cracking is a challenge for the concrete industry. Materials selection, environmental conditions, and field practices all have considerable influence on the propensity for early-age cracking to occur. This document focuses on thermal- and moisture-related deformations; both are materials-related and contribute to early-age cracking. The document provides detailed reviews on the causes of deformation and cracking, test methods for assessing shrinkage and thermal deformation properties, and mitigation strategies for reducing early-age cracking.

Report on Pervious Concrete (522R-10)
Pervious concrete is widely recognized as a sustainable building material, as it reduces storm water runoff, improves storm water quality, may recharge groundwater supplies, and can reduce the impact of the urban heat island effect. This report provides technical information on pervious concrete’s application, design methods, materials, properties, mixture proportioning, construction methods, testing, and inspection.

Report on the Physical Properties and Durability of Fiber-Reinforced Concrete (544.5R-10)
This document addresses the physical properties and durability of fiber-reinforced concrete (FRC). The effects of fiber reinforcement are evaluated for various physical, short-term, and long-term benefits they impart to the concrete mixture. A variety of test methods, conditions, and properties are reported. The various properties listed, in addition to the wide variety of the choices available in formulating matrix systems, allow performance-based specification of concrete materials using fibers to become a viable option. This document provides a historical basis and an overview of the current knowledge of FRC materials for tailoring new, sustainable, and durable concrete mixtures.
