A mixture of sulfur, plasticizer, and mineral aggregates that holds up under several corrosive conditions has been developed as a result of the US Bureau of Mines sulfur utilization program. A sulphur concrete tank used to store an extremely corrosive acidic leaching solution showed no signs of damage after 16 months. Sulfur concrete test slabs exposed to high concentrations of sulfuric acid for two years showed no signs of corrosion while slabs of portland cement concrete had virtually disintegrated. Because it resists attack by chloride ions and absorbs very little moisture (0.05 percent or less), the mix is highly resistent to salt water, thus lending itself to marine applications. Several saving tests in progress suggest it may provide a high-quality paving surface without the use of petroleum-based asphalt. Sulphex, a plasticized sulfur compound being texted by Southwest Research Institute, can be formulated to resemble either flexible asphalt or rigid concrete pavements.
