SulfCrete™
Next Generation Sulphur Polymer Cement
SulfCrete™ is the next generation of sulfur cement that is applicable for a wide range of construction projects. It can be a replacement cement/concrete in both the precast and ready-mix markets.
Unlike portland cement, SulfCrete™ cement comes in a pelletized form, which is environmentally stable with a long shelf life. To turn it into concrete, the product is melted and blended with aggregates based on the end-product strength requirements. In this regard, its casting is similar to the production of asphalt. OTBM provides the mixing equipment to accomplish this along with a certified training program.
SulfCrete™ offers higher strength at early ages when compared to portland cement, which makes it suitable for precast or prestressed concrete In a precast application it can be demolded very quickly after casting, enabling more efficient and cost effective turn-around.
Another key features of SulfCrete™ is its impermeability, which makes it resistant to scaling caused by freeze/thaw cycles. Unlike other materials, SulfCrete™ is incapable of entraining liquids or gases, which ensures that it remains stable in even the most aggressive sulfate and acidic environments. This benefit fits applications such as components in storm drainage and sewage systems, but also for precast or ready-mix roadway pavement.
SulfCrete™ meets or exceeds the physical requirements of ASTM C150 and AASHTO M85.
SulfCrete™ Benefits
High Early Strength
Recycled & Recyclable
Achieves full strength (up to 10,000 psi) in 24 hours
Every ton of SulfCrete created produces 95% less CO2 than concrete
Utilizes recycled concrete & asphalt as an aggregate and can be recycled and used as an aggregate itself
Accelerates Mold
Cycle Time
100% Reduction in Water Usage
High Resistance to Acid
Faster cure times means more efficient mold cycle time
Requires no water in production
Highly resistant to acid attack
Salt Water Resistant
SulfCrete can withstand long term exposure
to salt water
Water & Vapor Impermeable
Both water and vapor impermeable
Use Cases
1 / Precast Concrete Production
SulfCrete™ can be used in the production of an array of precast concrete products, such as pipe, sewer components, underground vaults, highway barriers and sea walls. Its curing properties enable quick turn-around of molds ultimately providing better economics for the precaster. As a water and vapor barrier it is also suitable for use in water collection and treatment facilities.
2 /Marine Applications
SulfCrete™ is highly resistant to saltwater and can be used in marine applications such as seawalls, docks, and wave abatement structures.
3 / Roadway and Pavements
SulfCrete™ can be used in the construction of roadways and pavements where its resistance to freeze/thaw cycles, water, and vapor impermeability, and high early strength development are essential. SulfCrete's impermeability to liquids and gases makes it less susceptible to scaling from freeze/thaw cycles, making it an ideal material for harsh environments.
4 / High Sulfate and Acidic Environments
SulfCrete™ can be used in concrete structures exposed to highly aggressive sulfate and acidic environments. Its high resistance to acids and impermeability to liquids and gases make it an ideal material for use in these environments.
5 / Encapsulation of Hazardous Waste
The technology behind SulfCrete™ was originally developed as a way to encapsulate toxic and hazardous waste materials, specifically mercury. Data shows that SulfCrete™will bind these wastes in a water/acid resistant shell and limit leachability to the parts-per-billion level. Besides mercury, this would also include chromium, arsenic, lead and other forms of waste.
