oXoCrete Features and BenEfits

OXOCRETE: CONCRETE PROTECTION & REHABILITATION

oXoCrete Solves Your Concrete Problems.
You only have two things to do with your concrete… protect it, or replace it.
With oXoCrete— you no longer have to replace it.
You can protect it and rehabilitate it to like new conditions for a fraction of the cost.

The oXoCrete System is designed to protect and rehabilitate concrete damaged from water penetrating into the concrete matrix-weakening the concrete matrix, reducing the pH from alkaline levels of 11 to low pH levels of 8 or less—and causing corrosion to reinforcing steel or rebar. The following provides a description of the features and benefits of oXoCrete.

Description of 

Increased Depth of Penetration

The increased penetration depth achieved by the OXOCRETE system sets the stage for the rest of OXOCRETE’s incredible outcomes and is unmatched by any concrete rehabilitation system in the world.

Exfoliation of Salt and Other Damaging Materials From Concrete

Salts are the nemesis of concrete. Once salts have permeated into the matrix of the concrete, concrete remains consistently damp and cause efflorescence of the salts to the surface. Coatings and finishes can’t bond to these surfaces. – they’re pushed off the concrete surface through the release salts, etc, via the capillaries and pore spaces which they originally permeated.

Note: Once salts have permeated into the concrete matrix, the concrete will remain consistently damp and cause efflorescence of the salts to the surface resulting in a surface with which coatings or finishes cannot bond. After OXOCRETE application, airborne seaside salts, salts of acids and other harmful materials are exfoliated from within the matrix the concrete.

Abrasion Resistance

The OXOCRETE CPR system application has shown to add substantial abrasion resistance and performance to concrete floors and ramps where excessive weight transfer and abrasive conditions exist. Testing where consistent abrasion occurs has shown the material to resist the effects of abrasion even in chemically affected environments and has resulted in minor maintenance since 2008.

Acid and Chemical Resistance

When the OXOCRETE CPR system has been used in highly corrosive environments it was proven that concrete exposed to such conditions result in severe degradation of the internal concrete matrix. The OXOCRETE CPR system has been proven to extract the salts and acids stabilizing the concrete and providing resistance to acids or chemicals penetrating the concrete.

Reduction and/or Elimination of Electrolytic Activity

Electrolysis or oxidation and corrosion of the reinforcing steel embedded in concrete is the single largest problem in infrastructure today. Once reinforcing steel is compromised, the entire structure is in danger. To increase the time between maintenance cycles, various methods (similar to those used in the marine industry) have been developed with sacrificial anodes that are attached at the oxidation site, and achieved via OXOCRETE application.

In instances where corroding conditions exist, OXOCRETE has demonstrated success in preventing further corrosion, and inhibiting or terminating corrosion all together.

Note: Utilizing ASTM’s 867 “Half Cell Method,” electrolytic activity was reduced to negligible activity on aged concrete structures on the Gulf and Atlantic Coast in the Florida Keys. Projects dating back to 2008 have resulted in no rehabilitative work on structures treated with the OXOCRETE CPR system.

Increased Flexural Capacity

Increased flexural capacity is demonstrated in multiple instances where flexural stressors are prevalent. OXOCRETE has demonstrated success in increasing flexural strength over conventional rehabilitation systems.

Note: Laboratory compression of cores has exhibited improved flexural capacity over conventional non-treated materials.

Increased Compressive Strengths

Compressive strength improved within the matrix up to 10” deep in existing concrete substrates once the OXOCRETE CPR system has been applied and before and after cores have been extracted from the project. We have resulting case histories that date back over 25 years showing test results with increases in PSI from 20% up to 294%.

Note: All cores are extracted and tested in accordance with ASTM standards by certified and accredited testing laboratories.  

Restored pH to Better Than New Levels

In every instance where the loss of pH in the concrete existed, the pH was restored to better than new levels when the OXOCRETE CPR system was applied. Concrete when new, has a pH of 11+, which passivates the corrosion of reinforcing steel.

The pH of concrete was measured utilizing a phenolthalein solution, both before and after OXOCRETE treatment. The results of the photo survey showed that the pH was fully restored.

Note: New concrete has a pH of 11+, which passivates the corrosion of reinforcing steel. Carbon dioxide can lower the pH through a process called carbon dioxide diffusion. When the OXOCRETE System is applied from the surface, it has fully restored pH to better-than-new conditions.
