Neutralization-induced damages
Concrete is alkalic, but carbon dioxide and water invaded into the micro-space of the concrete reacts and generates H+ ions, which in turn, neutralizes the concrete itself.
Aggregate-induced damages
Water smeared into the micro-space of the concrete induces hydration reaction and release a lot of alkali hydroxide, which in turn, reacts with aggregates of the internal structure of the concrete. This reaction further results in an expansion of the concrete and causes deterioration of the whole structure.
Damages caused by oxygen and moisture
After the deposition and curing of the concrete, reactive gases as air, oxygen, chloride, and moisture can smear into the concrete through the micro-space of the structure. The moisture and oxygen together cause corrosion of the iron bars resulting in ferrite oxide (Fe2O3) which expands several fold. This increased volume, in turn, causes further cracks in the structure.
Damages caused by repetitive freeze and thaw
The repetitive freezing (expansion) and thawing (shrink) of the moisture smeared into the micro-space will enlarge the space and more cracks, resulting in enhanced corrosion of the iron bars, breakages of aggregates, peeling off of the surface, and chipping off of the corners etc.
Principles of Dr.Crete’s protective effects
Produced with hydrophilic inorganic materials, Dr.Crete can smear into the micro-space of the concrete and induced chemical reactions among cement, sand, iron, aluminum, silicates, and the impurities contained in the concrete. The end product of the reaction is an air-tight concrete mass which fundamentally blocks penetration of air, oxygen, moisture, or any pollutants that can damage the structure.
