Although Alkali-Silica Reactivity (ASR) has created problems in concrete mixtures for centuries, the mechanism was not understood and documented until the mid-1930s. ASR is now recognized as a significant cause of concrete deterioration anywhere in the world where siliceous aggregates are found. In this blog article, we discuss what ASR is, the effect it has on concrete, prevention, and the equipment to use for testing.

This blog post provides insight into test methods and testing equipment for use in concrete resistivity testing. We discuss the use of the Proceq Resipod Concrete Resistivity Meter for surface resistivity and how to perform bulk resistivity.

In this month's blog post we will focus on standard-cure cylinders made for compressive strength acceptance testing. Including the importance of cylinder testing, a quick guide on the procedure, and the equipment needed in the field and lab.

It's important to run a complete set of tests, including air content and unit weight, on all fresh concrete batches, whatever the mix design. This is the best method to secure accurate and complete data that is very difficult to obtain later, and assures adherence to QC/QA requirements.

Comparing the differences between sulfur mortar capping and the use of neoprene pads with metal retainer rings will help you select the ideal procedure for your application.

Evaluating the differences between moisture rooms and curing tanks for concrete test specimen curing procedures will help you select the best option for your lab.

Understand the basic methods used to ensure your concrete samples live up to their full potential.
