adapted Fig 3-10 "Reinforced Concrete...." by James K. Wight
It is rare in the extreme that initial testing on some material exceeds the wildest expectations, especially if it is a garage development. In this case, the testing lab was not able to test ASTM 1609 “residual strength”, which routinely adds close to 100 psi (when “chopped” fibers used) so our numbers did not jump higher off the page.
Fiber Distribution Ring
TNSR Fiber Distribution Ring’s 12 boxes of fiber, each holding 1800 feet of fiber, means 21,600’ per truck load (10yd) at a cent a foot. So $22/yard increase in bare concrete cost ($125/yd): increased DURABILITY, increase flexural STRENGTH >40%, potential for removing need for rebar in flatwork, environmental immunity, and reinforcement equal at concrete edges disregarding harsh environments completely!
Deposits ADD Up
There are approximately 55,000 concrete trucks in the United States which implies lots of fiber distribution ring deposits! If each truck makes 3 deliveries per day and TNSR Systems only gets ONE (1)…Isn’t it impossible to believe a number like a BILLION FEET?
UHMWPE fibers continuously streamed into concrete may approach UHMWPE rope in tensile strength. Another feature is the ability to mix and match materials [copper, titanium, UHMWPE, graphene,…] adapting the concrete composite as requirements change. Because the fiber distribution ring is swappable, changing requirements can happen within a truck load.
Admire UHMWPE Strength!
NO steel Tiltup panel
This is the first full-size test of our composite concrete:UHMWPE system. While being at the small end of tiltup panels (8′ x 25′), it exceeded our expectations because success is rarely expected on the first attempt. This is truly invigorating!
Success on the first attempt was not expected by “experts”.
• Reviewing leading textbooks, like “Reinforced Concrete: Mechanics…” by James Wight, and thirty years of engineering reports informs you that one cannot significantly increase the tensile strength of concrete by adding fibers. In fact, interesting tests for Fiber Reinforced Concrete (FRC) like ASTM 1609 are not as commonly performed today because of this general understanding.
• The TNSR Delivery Mechanism continuously streams Ultra High Molecular Weight Polyethylene (UHMWPE) fibers, today’s strongest production fiber. FRC applications to this point have always used chopped fibers (~2″) added into the concrete mixer.
Would rebar add tensile strength to concrete if it were chopped into 2″ pieces?
