ACIDPROOF CONCRETE – LIGHTWEIGHT 54LW

Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data are subject to reasonable deviation.

Sauereisen Acidproof Concrete 54LW – with almost a half century of successful, varied service – is the original acid-resistant material for gunite construction. For those applications that require a lower K factor, lightweight materials, or higher temperature resistance.

54LW is potassium silicate, acid-resistant refractories for use as monolithic linings in chimneys, stacks, ducts, breechings, scrubbers, precipitators, sulfur pits, tanks, process vessels, floors and sumps. These two-component materials consist of Powder and Liquid which are mixed together on the job.

Benefits of 54LW include the capability to protect or restore acid attacked areas while avoiding the costs of brick or tile construction. Downtime will be reduced. (At 70° to 80°F, full operation can be resumed in 24-30 hours, depending on application). The acidproof concrete system typically incorporates an impervious, chemical-resistant membrane such as Sauereisen High Temperature Membrane 89.

CHARACTERISTICS

  • Potassium silicate-bonded.
  • Resists most solvents, oil, acids and acid salts (except hydrofluoric) over a pH range of 0.0 to 7.0.
  • Withstands water and vapor without special treatment.
  • Applied by guniting.
  • Fast chemical set – less construction delay.
  • Safe to use – nonflammable; will not support combustion.
  • Specially recommended for all concentrations of sulfuric, hydrochloric, nitric, and phosphoric acids.
