thermoplastic sulfur concrete

I am trying to find out where to buy sulfur concrete. I read that it achieves compressive strength in excess of 9000 psi in one day of casting. Does anyone know about it or any web sites for it?

RE: thermoplastic sulfur concrete

Are you referring to sulfur as an admixture or molten sulfur "concrete", a mixture of sulfur and flyash that is used for leveling and for a capping compound for testing concrete specimens?

Sulfur was tried numerous times as an admixture in both PCC and asphaltic concrete with various results, none of which seemed to be commercially viable. It has to be heated into a fluid mix and hardened to achieve anything like the strengths you referenced, which makes it impractical to use in a mixture with PCC.

Can be used as a leveling medium, but you have to remember that it leaches and the leachate can be highly acidic, thus creating corrosion problems.

RE: thermoplastic sulfur concrete

Sulfur Concrete indeed can exceed 9000 psi compressive strengths.  I am currently working on a project in Central Asia for utilizing SC as a road surface.  Basically, SC is a thermoplastic material so it is mixed and applied more like asphalt, although it is poured and finished like regular concrete.  The composition is about 10-12% sulfur, 86-88% aggregate, and 2% modifier.  The whole trick is to add a "modifier" to this material (about 2%) to keep it from becoming brittle.  The mixture is kept at 125-141C during mixing and pouring.  It attains nearly full strength within 24 hours.  Currently the best uses include chemical resistant floors (as the chemical resistance of SC is far superior to normal concrete).  If you want more information let me know.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
