STARcrete™ is a sulfurbased 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 subzero temperatures
Comparative Deterioration
IMMERSION IN 20% SULFURIC ACID
SulfateResistant 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.

The table below gives test results as compared to a typical Portland cement concrete using a 19 mm (3/4") washed gravel
with approximately 60% fractured face. Note that the relationship of compressive strength to modulus of elasticity can,
if desired, be varied with special additives.
