"This thesis represents a study which was made to evaluate and interpret the downstream variations in the quality of the Meramec River gravels as coarse aggregate for concrete. Since gravel deposits constitute a valuable resource for a region, it is desirable that extent and quality variations of these deposits are known. It was hoped that an evaluation of certain properties of the Meramec River gravels would assist in determining the value of the Meramec River as undeveloped aggregate source by indicating the relative quality of the gravels from alternate sites of the river. For the purpose of this investigation, representative samples from selected sites along the river were collected; engineering tests and petrographic analysis were conducted on those samples to evaluate their quality for concrete aggregates. Also an attempt was made to evaluate the effect of geologic conditions on the aggregate quality. It was found that gravels from the Meramec River, on the basis of their engineering properties, are a satisfy coarse aggregate source. Chert is the dominant rock type of the gravels. Petrographic examinations indicate they are potentially reactive aggregates. The results of the engineering tests showed little variation in the properties of gravel from the headwaters to the mouth. However, the lower portion of the river is judged to have the better quality aggregate. Although carbonate rocks constitute the most common bedrock in the basin, they form only a minor constituent of the gravels. Leaching and abrasion degradation are the main factors that cause the deficiency of carbonate rocks in the Meramec gravels"--Abstract, page ii.
