Sulfcrete is commercializing a Next Generation Sulphur Polymer Cement under an exclusive License from the US Department of Energy and Brookhaven National Laboratory. Sulfcrete uses byproduct material produced in oil and gas Refinement, to create a superior strength, low carbon, waterless alternative to Portland Cement, which for the first time can now be manufactured in economic parity to conventional Portland Cement.

Scientists at Brookhaven National Laboratory have invented a new, cost effective process to manufacture sulphur polymer concrete, with a stabilized sulfur binder using activated fillers (SSBAF).  This is the product embodied in Sulfcrete.  The new product replaces expensive ($2000 a ton) conventional additives with a lower grade organic additive ($20 a ton) enhanced by energetic mixing with fillers. The lower grade organic additive is also a by-product of the petrochemical industry. The process effectively displaces conventional portland hydraulic cement in certain non-structural applications with sulfur-based thermoplastic binders in a new, clean sulphur concrete product. 

Unlike concrete made of Portland hydraulic cement, the SSBAF concrete technology embodied in  Sulfcrete uses only sulphur, fly ash, sand, and an organic modifier in a unique composition to produce a concrete that has a number of advantages: 

⦁    Sulfcrete has compressive and tensile strengths which are twice that of portland hydraulic cement. 

⦁    Full strength is reached in a matter of hours rather than several weeks.
  
⦁    Sulfcrete is highly resistant to corrosive environments of acid and salt. For example, sulfates, which are known to attack      and compromise portland hydraulic cement, have little or no effect on the integrity of  Sulfcrete. 

⦁    Sulfcrete also has a relatively low melting point of 120°C. It can thus be processed easily in a heated, stirred mixing process.  

⦁    SSBAF used in  Sulfcrete also does not use any water in its manufacture. Hence, it is of non-hydraulic nature, highly suited for manufacture in arid and sub freezing environments.

⦁    Sulfcrete can be manufactured on economic parity with Portland cement using existing concrete and asphalt equipment.


As a result of these superior properties, sulphur polymer concrete in its new commercially viable breakthrough process embodied by  Sulfcrete has been proposed for use as a paving material and for the production of tanks, pipes, and other structures where durable concretes are required. Based on its superior properties for construction applications, the patent pending process using SSBAF embodied in the sulphur polymer concrete of  Sulfcrete can also treat and encapsulate radioactive, hazardous, and mixed wastes.  It has been applied to a wide range of waste types including evaporator concentrates, ash, and sludges.  Improved waste loadings have been achieved while exceeding waste form performance standards specified by the NRC and EPA.
