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. Through a variety of resources, this course will help unlock the benefits of improved quality.
What will you learn?
- How do you know if you have good quality? What should be your quality metric?
- How to become more profitable through better quality?
- What are all the key statistical calculations you need to know in concrete?
- How to control the mixing water content in concrete?
- How to deal with temperature and delivery time variations?
- What is the most effective way to ensure that your material ingredients are of good quality?
- How to improve batching accuracy, mixing uniformity?
- How to identify non standard testing and curing? How to improve testing quality?
- Tests a producer should do, internal audits and many more…
Who Should Attend?
This course will be of significant value to concrete producers that 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 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.
