The American Concrete Institute (ACI) has released its 2015 edition of the Manual of Concrete Practice.

Containing more than 240 documents, ACI said the manual is a comprehensive source of information.

"The Manual of Concrete Practice is a must-have for professionals and contains all the ACI documents needed to answer any questions about code requirements, specifications, tolerances, concrete proportions, construction methods, evaluation of test results and many more topics," said an ACI representative.

The Manual of Concrete Practice also includes the 2014 version of ACI 318, Building Code Requirements for Structural Concrete and Commentary.

The manual is available in a traditional hard copy version, which contains a set of seven books and a separate index, an easy-to-use USB drive version, or an online version.
