Purpose and Background
Improved concrete quality has far reaching benefits—in improved performance, reduced time and costs, a lower environmental footprint of concrete and an overall improvement in the quality of concrete construction. However it is hard to find a course focused on the subject of improving concrete quality. Based on quality surveys and award submissions, it has been observed that the industry does not commonly track quantifiable quality indicators and, as a result, the return on quality investments is not well understood. Improving Concrete Quality, a book authored by one of the instructors addresses these issues. That book, as well as other NRMCA resources provides the basic content for the course.
This course will delve into quantifying tangible and intangible benefits due to improved quality. It will discuss variability associated with concrete ingredient materials, manufacturing and testing—means to measure and thereby improve concrete quality. Basic statistical concepts will be presented to measure and monitor quality and to recognize when action is needed. Other key topics include recognizing abnormal material variation, tracking and improving batching accuracy including mixing water, internal testing, identifying non standard testing and initial curing, essential elements of a quality management system, internal audits, and tests a concrete producer should do.
Who Should Attend?
This course will be of significant value to concrete producers who will come away with readily implementable steps to manage variability and attain a more consistent product thereby seeing performance benefits and cost savings. Concrete ingredient material suppliers will benefit by understanding the needs of their customers and to develop information on variability that can help their quality systems.
The course will be of interest to contractors and testing laboratories. The course will help testing labs measure and improve testing quality.
Design professionals can benefit from this course by recognizing the opportunity for improved quality in concrete construction and the evolution to performance based specifications.
