• Abstract:

  Eight ASTM Standard tests were conducted at Brigham Young University in Utah using two types of pumice aggregates. The test methods used were as follows: C 138-74, C 136-71, C 33-74, C 40-73, C 192-69, C 39072, C 143-71, C 231-73.Results of tests are in the text, the appendix, and the figures. Conclusions drawn from the tests are:
  1. An all-pumice concrete mixture would not be practical because high cement content was needed to obtain a fair strength (7.5 bag/cu-yd yielded 3600 psi). See plots in Appendix.
  2. Pumice coarse aggregate with natural sands could be a possible mix even though high cement contents were still needed to obtain good strengths (6.7 bag/cu-yd yielded 4600 psi). Further tests would need to be made concerning long term effects of mica, freeze-thaw, etc.
  3. Bleeding of all mixes was a problem.
  4. Shrinkage may be a significant problem.
