Furan polymer concrete is inherently brittle and, in large masses, has a
propensity to shrink. It is used when resistance to acids, alkalies, and
solventss ucha sa romatic and aliphatic solventsi sr equired. It has been
successfully used in smallareas in the chemical, electronic, pharmaceutical,
steel, and metal workingi ndustries.
Polyester,v inyl ester,a nd acrylicp olymerc oncrete have strong aromatic
odorst hat can be offensive to installation and in-plant personnel.F ire
codes, particularly for acrylics, must be scrutinizedt oe nsure compliance.
Sulfur cement polymer concrete is flammable; consequently,the potential
for oxides of sulfur would preclude its use for most indoor applications.
Sulfur cement polymerconcrete is not recommended as aconcrete topping.
Polymer concretes are not to be misconstrued with polymer-modified
Portland cement concrete. Polymerc oncretes are totally chemical-resistant,
synthetic resin compoundsw ith outstanding physical properties. Polymer
concretesp asst he totali mmersion test at varying temperaturesf or
sustained periods. Polymer-modified Portland cement concrete can use
some of the same generic resins as used in polymer concretes, but with
different results.
The major benefits to be derived from polymer-modifiedPortland cement
concrete are as follows:
1. Theyp ermit applicationofc oncrete in thinner cross-sections.
2. Theyprovide improved adhesion for pours onto existing concrete.
3. Theyl ower absorption of concrete.
4. Theyi mprove impact resistance.
