SEMINAR PURPOSE & BACKGROUND

Dealing with concrete specifications, troubleshooting low strength problems and ensuring proper mixture submittals can be expensive and time consuming. This one-day course addresses potential conflicts in concrete specifications and ways to handle them before the project starts.

Utilizing a specification guideline document, several tips are offered on how to discuss specification requirements while saving money. This document suggests specification clauses and includes provisions incorporating the new ACI Building Code 318-08 exposure categories. It is the product of the review results of numerous concrete specifications belonging to large owners (Section 03300), and it has been reviewed and supported by the NRMCA Research Engineering and Standards Committee.

Troubleshooting low strength problems is perhaps the primary reason for back charges for a concrete company, all of which could be avoided almost entirely with knowledgeable concrete technical personnel. This seminar provides detailed instruction on the analysis of strength test results in order to identify the causes of low strength problems (including technician competence), and it provides guidance on tracking compliance with specification requirements. Non-destructive testing techniques to evaluate low strength problems (such as the Rebound Hammer) will be discussed, as well as other topics such as core testing, the evaluation of core test results for acceptance, and the assignment of responsibility.

Also covered during the seminar are the necessary details required for an efficient concrete mixture submittal, following the ACI 318 flowchart Selection of Concrete Mixtures. An analysis of a typical mixture submittal is conducted as a group exercise.

FORMAT & AGENDA

The course will be taught in a one-day format. Attendees can choose to register for the whole day, or register for half of the day (either first half or second half) at a reduced rate.
 

WHO SHOULD ATTEND?

Producers, contractors, engineers and testing labs will find the discussions on investigating low strength problems very helpful to avoid issues that impact partnering, project cost and schedule. Understanding how to do a proper mixture submittal is an essential function for the concrete producer.
