Description
This presentation will cover research conducted by South Dakota State University under the Mountain-Plains Consortium Project 437 and with additional funding from SDDOT. There is little guidance for SDDOT pertaining to the use and testing of FRC. There is also lack of information about new fiber products that have been introduced to the market in recent years. A comprehensive literature review, as well as interviews with SDDOT and other DOT personnel, were carried out in this study to evaluate past FRC experiences, effect of different factors on the properties of FRC, and existing FRC design and construction practices. The effect of fiber type and dosage on air content, slump, flexural strength, compressive strength, and impact resistance was examined by conducting laboratory experiments on FRC mixes incorporating five different fiber types and four different fiber dosages.
The presentation will include:
- Results of the literature review and DOT interviews.
- Summary results of 21 mix designs regarding concrete properties of slump, compressive strength, flexural strength, etc.
- Suggested guidance for FRC design, construction, and testing.
