Concrete Contamination and Its Effects on Coating Work

Oils and fats can cause two problems with concrete. One isattack; the other is contamination. Crude oils that are highin sulphur can cause acid attack, especially when water ispresent. Also, sulphur-oxidising and sulphate-reducingbacteria have been known to attack the cement binder incrude oil storage vessels made of concrete.

How To Encapsulate Contaminated Concrete Cure for ...

Now many state and local pollution control agencies have found that encapsulating contaminated concrete is the most economical and long-lasting solution for existing contamination. 100%-solids epoxy can seal contaminants into the concrete with layers of 10 to 100 mils thick. In effect, the encapsulation works like an insect trapped in amber.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...
