Inhibits rusting of reinforcing steel
Phoscrete has the unique ability to protect imbedded steel from corrosion. When steel corrodes, it creates pressure that causes the overlying concrete to crack. This creates a "domino effect" in which the imbedded steel is further exposed to air and water, increasing its corrosion. In addition, when concrete cracks, the water that enters may freeze and even further crack the concrete. Phoscrete actually inhibits rusting of reinforcing steel when used to repair deteriorated concrete where re-rod is exposed.
Resists freeze-thaw cycling
Other concrete repair materials are porous (usually with at least 10% porosity). Therefore when exposed to freeze-thaw cycling, water enters the material, freezes, and causes the material to fail, both internally and on the bond line between it and the existing concrete. Phoscrete® has less than 3% porosity, so even when exposed to drastic temperature changes and freeze-thaw cycling, the Phoscrete® repair will last.
High early and ultimate strengths
Phoscrete achieves substantially higher early strengths and substantially higher ultimate strengths than other concrete repair materials on the market. These higher early strengths allow Phoscrete® to be exposed to traffic sooner. Typically Phoscrete® may be exposed to rubber tire traffic after only thirty minutes. Phoscrete® higher ultimate strengths make it the clear choice for long-term applications.
