ABSTRACT
ABSTRACT: The aim of this study was to formulate sulfur polymer concrete having a workable consistency, good mechanical properties and high durability. In doing so novel modified sulfur was successfully prepared, which contains, in addition to the sulfur, a particularly polymeric material. Characterization as well as structural analysis of the modified sulfur was performed by C, H, S elemental analyzer, FT-IR spectra, x-ray diffraction, SEM, TGA and DSC. Comparison between sulfur concretes (using unmodified sulfur) and sulfur polymer concrete (using unmodified and modified sulfur) in addition to sand and fly ash was evaluated with respect to compressive strength, crystallization behavior, homogeneity, cumulative percentage of pore sizes, and thermal behaviors. Proper grain size distribution of the physical admixtures and suitable selection of manufacturing technological procedures have led to manufacturing novel sulfur polymer concrete with low porosity and high mechanical strength.
