    Abstract

    Sulfur concretes are typically brittle. Sulfur concretes that are less brittle have been produced and tested for durability. Specimens were immersed continuously for up to 200 days in various salt solutions and seawater. Comparison of these specimens with companion specimens kept in air and distilled water showed no adverse effects in terms of compressive strength and modulus of rupture; no cracking was observed and dimensional changes were similar for all specimens. When subjected to temperature cycling, compressive and flexural strengths of some sulfur concretes were reduced, the largest effect being observed in flexure. Preliminary tests for resistance to freezing and thawing showed no detrimental effects and material left outdoors for 18 months has suffered negligible change due to weathering. The abrasion indexes of these materials are between typical portland cement and asphaltic concretes. Comparison is made with results for a typical brittle sulfur concrete.
