Reinforced
cement
Cement is an alkaline medium. This is an inhibiting factor on the
use of glass as concrete reinforcement since it leads to early degradation.
This has lead to the development of a special product for this application,
so-called alkali-resistant glass. Alkali-resistant glass fiber is
a high-modulus fiber (10 times greater than polypropylene) with
a tensile strength three to four times that of steel. It is an ideal
fiber for the reinforcement of cement matrices. Some of the interesting
properties of glass fiber cement composites are their surface finish
(imitation stone or slate), low weight, capacity to be molded into
complex forms, resistance to crack spreading, non-flammability,
etc..
The combination of these different properties enables these products
to find many applications in general construction, external walls,
civil works (acoustical barriers, sewer piping, gutters, and so
on), architectural moldings (column capitals, porticos, etc.), and
as a replacement for asbestos (corrugated plates, fire break walls,
piping, etc.).
