Abstract: Industrial applications of modified sulfur concrete (MSC) have been extremely successful in areas of high corrosive activity such as load-bearing floors, walls, and sumps of chemical plants. However, there have been no research and development efforts involving the use of this high-strength, corrosion-resistant material in the very demanding structural component field. Designers require extensive structural test results to establish the confidence necessary to specify MSC as a structural material in any major structure. The objective of this study was to determine the applicability of MSC to the construction and repair of structural components and load bearing surfaces. A series of tests were conducted on MSC to determine mechanical properties important to structural design, freezing-and-thawing performance data, bonding of MSC to portland-cement concrete (PCC), and a series of limited reinforced MSC beam tests to compare with PCC structural design criteria. In general, MSC behaves similarly to a PCC with a comparable compressive strength. The modulus of elasticity and Poisson's ratio of MSC are comparable in magnitude to that of a PCC of comparable strength. Beam tests indicate that MSC appears to conform to the basic assumptions of reinforced concrete beam design including the formation of an effective moment-resisting couple. The ductility of MSC in the postyield regime, however, has not been determined in these tests.
