PROPERTIES

STARcrete™ is a sulfur-based concrete with unique properties. General properties of STARcrete™ include:

  • Extreme corrosion resistance
  • High physical strength
  • High fatigue resistance
  • Low permeability
  • Fast setting
  • Avoids the usual freezing problems in sub-zero temperatures

IMMERSION IN 20% SULFURIC ACID

Sulfate-Resistant Portland Cement Concrete STARcrete™
AFTER THREE WEEKS AFTER THREE YEARS

The properties of STARcrete™ can be tailored for specific applications, e.g., where toughness or impact resistance may be required, or for use in chemical tanks and floors where continuous exposure to acids may occur.

By selecting appropriate aggregates, the density of STARcrete™ can be varied over a wide range. Cost is governed by source and supply of suitable aggregates, as well as sulfur, when comparing it with normal Portland cement in developing suitable mix designs recommended for specific applications.
