Environment and health
The conditions related to environmental capability for cement admixtures and additives are the same as those for concrete. No pollutants are liberated during the entire life cycle of GFRC, Until ultimate disposal. The environmental comp atibility is therefore ensured, subject to adherence to usual measures. If organically structured additives are used, the limit values in the national codes of practice must be observed.
The 13mm glassfiber used in GFRC is considered non-harmful to health.
It has been proven that fiber with diameter of less than 3um are hazardous. Fiber of such diameters and less are capable of been suspended in the air.
Even when glassfiber reinforced concrete is mechanically processed e.g. by
By sawing, drilling, grinding, this will not cause the glassfiber to split up into thinner fibers. Therefore any of the typical equipment may be used in processing the material, even after hardening when the instructions specific to the equipment used are observed.
