Abstract:
To overcome major construction delays, the writer developed and directed an extensive testing program to establish blast vibration limits based on the actual performance of concrete matured up to 24 hr after casting. Test results quantified the maturing concrete’s tolerance for considerably higher construction vibrations than those historically published as common industry limitations. As an outgrowth of the initial test experience, concrete performance information has been further expanded by a literature search and correlated to round out threshold data to include more mature concrete and longer term vibration exposures. The condensed report represents a significant, comprehensive quantified data source and general recommendations to aid in planning limits for concrete placements and identifying preplacement monitoring and/or testing needs.
