Investigation of testing materials for the Chickamauga Lock and Dam Reconstruction Project

Abstract

In support of the U.S. Army Corps of Engineers (USACE) Nashville District, a preliminary investigation of concrete materials was conducted pursuant to reconstruction at the Chickamauga Lock and Dam located near Chattanooga, TN. 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, two type I/II cements, a fly ash sources, a slag cement, a silica fume, and a limestone powder. 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, petrography, and freezing and thawing. All cementitious and admixture materials were tested for chemical and physical properties based on appropriate specifications. This report presents the material characteristic results determined by laboratory testing in accordance with American Society for Testing Materials (ASTM) procedures or regulating specification criteria.
