Mechanism of plastic cracking resistance of FARCOFIBER
FARCOFIBER P.P improves the early tensile strain capacity of the concrete at the critical period 2-6 hours after placing. It therefore reduces crack frequency and size. FARCOFIBER P.P be cause of their very high surface area, are more effective than steel mesh.
At a later stage when the concrete has matured and begins to shrink, FARCOFIBER P.P bridges the cracks and therefore reduces the risk of failure.
FARCOFIBER P.P reduces the bleeding of concrete by means of more efficient hydration control thus reducing the development of intrinsic stress. Plastic settlement cracks are subsequently reduced due to the greater control over bleeding of water to the surface
Tests show that the fibers increase the apparent cohesiveness and reduce the slump of a concrete mix.
Additional water must not be added to increase the slump of fiber concrete mixes.
The placeability of the fiber dosed concrete and its compact ability under vibration is much better than indicated by the lower consistency in the slump test.
Method of Use
The fibers may be added at either a conventional batching / mixing plant, or by hand to ready – mix truck on site.
When dry mixing, the fines should be added first followed by the fibers and the coarse aggregates.
When wet mixing, the consistency of the matrix should be neither too fluid (nor stiff), to ensure that the fibers are immediately dispersed and inter mixed.
The fibers are added to the mixes at the rate of 800gr to 1000gr per m³ of concrete and 1000gr to 2000gr per m3 of mortar.
FARCOFIBER PP is suitable for use with cement replacement materials e.g. Fly ash, silica fume, blast furnace slag cement concrete.
With other Admixtures
FARCOFIBER P.P is compatible with other chemical admixtures.
Other product info
No special precautions are necessary when pouring into moulds or shutters.
Fiber dosed concrete mixes will flow around rein forcemeat, into restricted areas and against mould faces in the same manner as conventional concrete of similar mix design.
Fiber dosed concrete mixes may be hand tamped or vibrated by conventional means to provide the necessary ompaction.
It is essential that all normal good curing procedures for conventional concrete are strictly followed.
The fibers are from polypropylene and should not be used when steam curing is to be carried out at temperatures in excess of 140˚c.
FARCOFIBER P.P is supplied in 5kg bags.
Keep the packages of FARCOFIBER P.P on a clean and dry surface, away possibility of damage.
