摘要

Elemental sulfur possesses a number of interesting properties such as high electrochemical capacities, high relative indices, corrosion resistance, thermoplastic characteristics, high compressive strength, and antifungal properties. These properties make it a promising candidate for possible use as a construction material for niche applications in the chemical industry. In this article, we have attempted the preparation of sulfur composites using refinery solid waste such as spent fluid catalytic cracking (FCC) catalysts. Modified sulfur is mixed with spent FCC catalysts with different compositions to make sulfur composite blocks. Performance of these materials was tested and compared with cement concrete under different environments such as acidic conditions, alkaline conditions, saline water, and hydrostability. Based on the results of performance testing such as compressive strength and leaching analysis, sulfur composite shows better stability in such critical environments. Sulfur composite materials are useful construction materials for coastal saline areas, a corrosive acid environment, and could find application as an antifungal coating of surfaces.
