The feature of this year's work has been the completion of tests to determine the effect of weather conditions on outdoor curing of concrete masonry units. Block were made each month during the year, beginning November, 1925, and tested at 28 and 90 days after the usual initial curing followed by storage in the open. These tests were made through the cooperation of the Diamond Block Co., St. Paul, Minn., and the structural division of the civil engineering department, University of Minnesota, and the test program was conducted under the direction of Earle D. McKay, a member of this committee. The results of this investigation are given in Appendix 1 of this report.
