IRCI technical guidelines revised

The International Concrete Repair Institute (ICRI) has released two new technical guidelines and revised an existing document. “Pictorial Atlas of Concrete Repair Material Mixing Equipment” aims to aid in consistent specifications for equipment used when mixing concrete repair materials, while “Guide for the Evaluation and Repair of Unbonded Post-tensioned Concrete Structures” will offer an introduction to evaluating and repairing concrete structures post-tensioned with unbonded single-strand tendons. Finally, the revised “Guide for Inorganic Repair Material Data Sheet Protocol” now includes updates on testing and reporting for cement-based repair materials.
