Module 4 covers quality control measures necessary for a Concrete Surface Repair Technician to perform a pre-placement inspection. This module discusses mock-ups and trials, and presents a pre-placement checklist. The checklist training covers specification criteria, general information, existing concrete condition (presence of chlorides/carbonation, repair area configuration, and prepared surfaces), reinforcing steel condition (steel cleanliness, section loss, lap length, and concrete cover/bar coatings), and repair material condition (origin, storage, and mixing). Slump of conventional concrete, slump flow of self-consolidating concrete, and making of test cylinders is also detailed in this module.
To complete this module, you will need a copy of the Pre-Placement Inspection Checklist, ASTM C143/C143M, ASTM C1611/C1611M, and ASTM C31/C31M.
