A well-executed Quality Control program is vital to the success of a precast operation. This Quality Control module will present a number of topics that will build on NPCA’s Quality Control Manual and support the NPCA Plant Certification program. Coursework covers aggregate gradations analysis, aggregate moistures, hot-temperature concrete and cold- temperature concrete. Attendees will learn why water-to-cement ratio is so critical to concrete properties and the need for frequent testing to assess water absorption and movement in concrete. Adjustments to batch quantities of constituent materials based on aggregate moisture conditions are reviewed to optimize concrete mixture properties. The Maturity Method will be presented in layman’s terms so that a precaster can accurately assess strength development and timing of construction operations. Additional topics include averages and trends in data, reinforcing steel. Please bring a calculator for this course.
