HI-STRAIN CONCRETE

Substituting 50% slag cement for Portland cement reduces greenhouse gas emissions by more than 40%

During compression testing, the Hi-Strain™ organic concrete  exhibits a period of energy absorption, characterized as strain hardening, shown as a “flat-line” interval, never present in conventional concrete  Typical strain curves of conventional concrete at maximum compression are around 0.002.  The Hi-Strain™ organic concrete ‘strain curves before failure’ are as much as 35 times that of conventional concrete.

The result of 6 years of research and development, Hi-Strain™ Concrete exhibits a unique personality: 

  • exhibits high flexural strength—over 1300psi unreinforced

  • is impermeable to water

  • has strong performance under freeze thaw conditions

  • is never subject to ARS

  • is highly resistant to sulfate attack

  • exhibits strain hardening, a trait not found in conventional concrete

  • is fireproof

  • has high R value of 1.79 per inch thickness

  • is 20-35% lighter than conventional steel-reinforced concrete

  • utilizes exclusively basalt rebar when reinforcement is required

  • incorporates hydrophilic nylon fiber for minimal shrinkage cracking and greater cohesion

All mixes have been thoroughly tested at both University of Tennessee Chattanooga and Heidelberg Cement Laboratory in Doraville GA.  Product prototypes have been tested at NC State University Constructed Facilities Laboratory, RailTEC facilities at UIUC University Illinois, and at Transportation Technology Center TTCI Pueblo CO.
