INVESTIGATION OF SULPHUR AS A STRUCTURAL MATERIAL

The feasibility of using sulphur-reinforced glass fiber composites was demonstrated in the field for the construction of shelter floors and helicopter landing pads under a previous study. The subject program was undertaken to optimize the system from the standpoint of strength, fire resistance, abrasion resistance, and economy. As a result of this program, a glass fiber mat was developed which was compatible with sulphur formulations. This mat, designated as GP 2-oz/sq ft Sulfophil III, has a terpene polymer sizing. The optimum sulphur formulation prepared during the course of this program consisted of 96 percent sulphur and 4 percent dicyclopentadiene. Flexural strengths of 4850 psi were attained with this composite which has good fire resistance and greatly improved abrasion resistance. The use of highway marking paint as a coating material was demonstrated to also aid the fire and abrasion resistance of sulphur-glass fiber composites. The feasibility of making building blocks of sulphur foam was demonstrated by the production of eighty blocks comparable in size and shape to lightweight aggregate blocks. The mechanical properties of rigid sulphur foam were determined to sufficient for wall construction. (Author)
