A new topic in the Technology in Practice (TIP) series is available – TIP 17 – Drying Shrinkage of Concrete. TIPs are developed by the NRMCA Research Engineering and Standards (RES) Committee as educational material directed to concrete producers. TIP 17 discusses the mechanisms of volume change and factors that impact shrinkage of concrete. It provides guidance on developing concrete mixtures for shrinkage specifications and the test method for shrinkage.
