A new topic in the NRMCA Technology in Practice (TIP) series is now available, TIP 18 – Managing Concrete Temperature for Specified Requirements provides guidance to concrete producers on managing temperature of freshly mixed concrete to comply with specification limits or for quality reasons. It provide the typical equations and charts that can be used to estimate concrete temperature or to determine quantity of hot or cold water or ice to use to achieve target temperature. The TIP only focusses on temperature management and not mixture development for hot or cold weather concreting. TIP 2 – Establishing the Required Average Strength of Concrete Mixtures, has been revised.
TIPs are developed by the NRMCA Research Engineering and Standards (RES) Committee and are intended as an educational resource for ready mixed concrete industry personnel. They can be previewed on the NRMCA Web site.
