Abstract

Results of a testing program to compare the cyclic triaxial behavior of Monterey No. 0 and No. 0/30 sands are presented. Monterey No. 0 sand, the standard sand used by Silver et al in 1976 to establish the performance specification for cyclic triaxial systems, is no longer available and a replacement is needed. The supplier of the test sand, Lone Star Industries, stopped producing No. 0 sand in 1977, and the 4500-kg (10 000-lb) supply stockpiled by the University of California at Berkeley is exhausted. Since 1977, Lone Star Industries has filled requests for Monterey No. 0 by shipping Monterey No. 0/30 sand. The results of a duplicate testing program conducted at two independent laboratories lead to questions regarding the validity of substituting No. 0/30 sand for No. 0 sand. When tested under identical conditions, the Monterey No. 0/30 sand yielded higher cyclic strengths than did Monterey No. 0 sand.
