Commonly, bleach-making consists of mixing sodium hydroxide (caustic) with chlorine to produce sodium hypochlorite of various strengths. For example, bleach for home laundry use is weak while bleach for disinfection is stronger. Industrial bleaching operations, such as in pulp and paper applications, typically require strong bleaching action.
Polymer concrete is one of the most durable, longest-lasting, and corrosion-resistant materials available for industrial infrastructure. This class of products consists of a matrix composed of heavy-duty aggregate and either chemical-resistant resin or cement binder. These castable materials may offer up to five times the physical strength compared to standard Portland-based concrete.
