Roofp Lax Sp 300 Is Single Component Liquid Reinforcement Protection Super Plasticizing And Water Reducing Admixture. 
How Reinforcement Corrosion Takes Place And Concrete Deteriorates:
  • 0Water Ingress Is A Major Contributor To Many Of The Concrete Related Problems That Cause Deterioration Of Concrete Within Concrete Structures. These Include Corrosion, Chlorides, Carbonization, Alkali-silicate Reaction, Freeze/Thaw, And Chemical Attack. 

Water Ingress And Corrosion:
  • The Two Most Common Causes Of Reinforcement Corrosion Are (I) Localized Breakdown Of The Passive Film On The Steel By Chloride Ions And (Ii) General Breakdown Of Passivity By Neutralization Of The Concrete, Predominantly By Reaction With Atmospheric Carbon Dioxide. Sound Concrete Is An Ideal Environment For Steel But The Increased Use Of Deicing Salts And The Increased Concentration Of Carbon Dioxide In Modern Environments Principally Due To Industrial Pollution, Has Resulted In Corrosion Of The Rebar Becoming The Primary Cause Of Failure Of This Material. The Scale Of This Problem Has Reached Alarming Proportions In Various Parts Of The World. Corrosion Deterioration In Concrete Normally Occurs Due To An Electrical Reaction Caused By Exposure Of The Reinforcing Steel To Oxygen And Moisture. When The Iron In The Steel Oxidizes, It Expands, And Causes Tensile Stress In The Concrete Until Eventually The Concrete Cracks Or Spalls. As The Cracks And Spalls Begin To Occur Increased Amounts Of Water And Oxygen Access The Reinforcing Steel Increasing The Rate Of Corrosion And Accelerating The Deterioration Effects. Stopping Water Ingress Will Also Stop The Effects Of Corrosion On The Reinforcing Steel Thereby Preventing Tensile Stress Cracks And Spalling. 

Water Ingress And Chlorides:
  • When A Concrete Structure Is Often Exposed To Deicing Salts, Salt Splashes, Salt Spray, Or Seawater, Chloride Ions From These Will Slowly Penetrate Into The Concrete, Mostly Through The Pores In The Hydrated Cement Paste. The Chloride Ions Will Eventually Reach The Steel And Then Accumulate To Beyond A Certain Concentration Level, At Which The Protective Film Is Destroyed And The Steel Begins To Corrode, When Oxygen And Moisture Are Present In The Steel-concrete Interface. Even High Alkalinity Will Have Minimal Abilities To Reduce Deterioration. If Water Ingress Is Stopped Even Cast In Chlorides Will Not Deteriorate The Concrete. 

Water Ingress And Carbonization:
  • Corrosion Can Also Occur Even In The Absence Of Chloride Ions. Carbonization Is A Chemical Reaction Between Carbon Dioxide In The Air And The Calcium Hydroxide In The Hydrated Cement Paste And With The Presence Of Moisture Reduces The Ph Of The Concrete Through The Creation Of Carbonic Acid. Over Time This Process Will Lower The Ph As Low As 8.5 Of The Concrete Thereby Permitting Corrosion Of The Embedded Steel. By Stopping Water Ingress The Effects Of Carbonization Can Be Dramatically Reduced.

Features:
  • Highly corrosion resistant admixture.
  • Provides high early strength.
  • Binds with iron rebar in the concrete and protects against corrosion.
  • Makes concrete water tight.
  • Increases workability of concrete mix and producing pumpability.
  • Provides excellent bonding adhesion with concrete to reinforcement.
  • Highly crack resistance.
  • Economicalwhen comparedwith epoxy coatings to the rebars, surface coatingson the concrete structuresetc.
  • Non-toxic
