• Abstract:
  The overall objective of the work contained in this report is to develop an ALDOT procedure to evaluate core strength results obtained under various conditions. Since there are many factors that influence the apparent strength of cores, strength correction factors must be applied to core strengths in order to convert them to a standard which can be compared with specified 28-day design strength. The following major factors that affect the relationship between the in-place strength and the strength of molded cylinders were assessed in this project: concrete age, concrete strength level, coarse aggregate type, degree of microcracking and difference in strength gain due to using different cementitious materials in the concrete mixture.
