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.
