• Why Corrosion is a problem?

What justifies the use of MST-BAR™ in today's infrastructures

• Governments & Taxpayers can no longer afford to pay concurrently for replacing, maintenance and expansion of infrastructure

• Corrosion is a dangerous and extremely costly problem and is draining the economy silently

• Safety of infrastructures can become problematic when subjected to harsh environmental conditions

• Steel is an old material, it’s great but often does not fit some applications!

• Typical example of Corrosion on bridges & Seawalls

• Typical example of corrosion on bridge decks

• Typical example of corrosion on Marine Structures

• Typical example of corrosion on Marine Structures

MST-BAR™ -Mega Strength Bar

Mechanical & Physical Properties of Straight GFRP

Stress-Strain Curves

Steel’s maximum stress level is 500MPa and GFRP is above 1000MPa for the same diameter. That is twice the load capacity of steel.

Zero corrosion: 100% resistance to any & all harsh environmental factors, No rusting High chemical resistance: Impervious to salt and other chemical attacks High tensile strength: 2 x stronger than steel with tensile strength of 1000MPa Light weight: 4 x (i.e. 73%) lighter than steel, (2100 Kg/m3 vs.7800 Kg/m3), Ease of transportation Long life span: over 100 years life span (GFRP) vs 25 years (Black Steel) High fatigue life: 20 x higher resistance under cyclic loading (440,000 cycle vs. 40,000 cycle) Non Conductive, & Non-Electromagnetic: Ideal for high electrical field, e.g. power stations Non Magnetic: Ideal for hospitals, MRI rooms, laboratories & other uses Radar Transparent: ideal for Airport Low thermal conductivity: Makes it suitable for use in hot and cold environments, power plants Low thermal expansion: Very low thermal expansion factor results in compatibility with concrete High bonding strength: Much greater bonding strength to concrete (20 Mpa) Ease of cutting & handling: Faster & cheaper installation and site handling Fire rated: Capacity to stand for more than 3 hours in direct fire with minimum concrete cover Sustainable to environment: Environmentally friendly, less Green House Gases while transporting High durability & performance: No maintenance required, No additional project cost, Major savings Min. concrete cover: requires minimum concrete cover i.e. 38mm, (2 ½ x less cracking of concrete) Detection by GPR : Easily detected by GPR No waterproofing: For bridge decks, unique saving for future

Advantages of MST-BAR™ Over Steel Rebar

Dis-advantages of MST-BAR™ Over Steel Rebar

CONCLUSION:

MST-BAR® it is proven for its long-term saving with life of over 100 years vs Black steel of 25 years

MST-BAR® with its proven higher performance not only will not add additional costs to the project; it will certainly result in major savings

Cost Study: BLACK STEEL

Chloride ions, moisture and salts will penetrate through the membrane and begin corroding its top reinforcement

CONCLUSION: 25 years after the road construction, its asphalt surface will have to be rehabilitated, the membrane would require replacement and the upper reinforcement would corrode needing to be replaced. Considering the life span of MST-BAR® at well over 100 years, the savings that it brings to any and all construction projects is undoubtedly substantial.

COST SAVINGS OF MST-BAR™

Transportation Costs, 4 times lower due to its 73% lighter weight

Minimum required concrete cover, 38mm for bars #2 -5 and 50mm for bars #6 -8, (the regular steel bar concrete requires 65mm)

Increase in labor performance and less fatigue for labors during placing the bar result in faster installation

MST-BAR® price with its proven higher performance will not add any extra cost to the project however it will result in saving.

40-60% less expensive than stainless steel rebar while MST-BAR® has much higher performance than the most expensive Stainless-Steel

No water proofing membrane, a unique cost-saving feature

NEVER Epoxy coat paint, re-patch the concrete or replace the rusted bars is no longer needed

MST-BAR, does not required any maintenance
