Abstract:
The autogenous volume change was measured in mass concrete mixtures having cementing materials, portland cement, and pozzolan, ranging from 222 to 302 lb per cu yd ( I32 to 179 kg/m3 l Some concrete contained pozzolans replacing 30 percent of the portland cement by absolute volume and others contained no pozzolan. One mixture contained a 50 percent pozzolan replacement. Seven pozzolans from a wide range of sources were used. Observation periods have extended to 3 years. This investigation was performed in connection with the U.S. Army Corps of Engineers’ design of Dworshak Dam, North Fork Clearwater River near Orofino, Idaho.
