Description

This course presents the research and experience on the relationship between concrete strength assessments based on 6 x 12 and 4 x 8 in. test cylinders. The presentations describe the advantages and disadvantages of each cylinder type, and the differences and the significance of the differences between strength assessments of each type of cylinder type. Also discussed is microwave oven testing that is used to determine water-cement ratio and ensure durability requirements.

Table of Contents

Learning Objectives:

1. Identify the variations and differences in strength measurements of the “same” concrete using “different” standard size test specimens;

2. Explain the pros and cons of each of the standard test sizes, and whether the physical size of the test specimen or the number of samples constituting a test create significant differences between them for the assessment of the 28-day compressive strength;

3. Relate 28-day compression strength testing and the variability to quality assurance of concrete so that attendees can answer for themselves whether size matters; and

4. Consider factors other than specimen size, such as quality testing and water content controls that, perhaps more significantly, affect the production of quality concrete
