dc.description.abstract | The investigation described in this report was conducted for the U.S. Army Engineer District, Pittsburgh as part of a preliminary investigation of cementitious materials and concrete design pursuant to construction of Charleroi Lock and Dam Monongahela River Reconstruction Project. Local materials provided to the U.S. Army Engineer Research Development Center (ERDC) for testing included three different coarse aggregate gradations, two fine aggregate sources, a type II (MH) cement, four fly ash sources, a slag cement, a silica fume, a limestone powder, five admixtures, and two water sources. Aggregate tests consisted of sieve analysis, specific gravity, absorption, materials finer than No. 200, organic impurities, soundness, LA abrasion, clay lumps and friable particles, flat and elongated particles, lightweight particles, and petrography. All cementitious, admixtures, and water-source materials were tested for chemical and physical properties based on appropriate specifications. In addition, four mixture proportions developed by the ERDC for this project in 2005 were scaled to determine the early stiffening of mortar, freezing and thawing, and heat of hydration. This report presents the material characteristic results determined by laboratory testing in accordance with American Society for Testing and Materials procedures or regulating specification criteria. | en_US |
