Determination of Test Methods to Quantify the Effects of Organic and Inorganic Constituents in Silica Sand Used for Construction

Quality control of sand and fine aggregate is of paramount importance to ensure the structural adequacy, long-term durability and sustainability of structures owned by the Florida Department of Transportation. To ensure the organic components within sand do not exceed minimum threshold values, an evaluation of the materials as well as the test methods themselves will be performed as part of this research project. The results from the research project BEB28 suggest that there is a good correlation between the results obtained from the Modified Walkley Black (MWB) method and elemental analysis via combustion (EA) method. The two methods yield similar or consistent measurements of organic carbon content in soil samples. Such correlation is valuable because it indicates that both methods can be used interchangeably or in conjunction to assess soil organic carbon levels. This correlation strengthens the reliability and applicability of both techniques in soil research and management.
