Acid Resistant Concrete Additive Production Process

  • Precast Concrete Pipe Durability

    Acid attack of concrete is a surface attack, in which the acid is neutral-ized by the concrete alkalinity, so that without acid replenishment, the reaction stops. Continuous replen-ishment of acid with a pH below 5.0 is considered aggressive and below 4.0 is highly aggressive to buried concrete pipe. Exterior acid attack, although

  • Polymer Concrete vs. Polymer Modified Concrete | ErgonArmor

    Degradation of the concrete might take longer if it is very dense and, therefore, has less surface area. In an acidic environment, the relative improvement in chemical resistance of polymer-modified concrete over Portland cement concrete is usually not sufficient to ensure its structural integrity long-term.
