The fibers are added to the mix at about 2% to 3% for premixed GFRC or 4% to 6% by weight for spray-up mixes. Many GFRC experts will also use silica fume, metakaolin, or other pozzolans in their mix.
Three different cases have been selected: a fiber-reinforced concrete with 80 kg/m 3 fibers type Dramix 65/35 (mix D), a second one containing 50 kg/m 3 fibers type Dramix 65/60 (mix E) and a concrete with a hybrid fiber reinforcement consisting of 25 kg/m 3 fibers Dramix 65/35 and 25 kg/m 3 fibers Dramix 65/60 (mix F).
Design of fibre reinforced concrete Here the use of fibres allow for the ready mix truck to discharge directly on the slab base at the point of use. Macro Synthetic fibres are very useful for the design of ground bearing slabs for the following reasons: The Durus range of fibres improves the apparent flexural toughness of the composite concrete/fibre material. This provides an improved

Several worked examples are included to …
some reinforced cement composites were probably due to alkali attack of the fibres by the pore water present in the cement matrix. Suggestions to resist this deterioration included changing the alkalinity of the pore water, replac-ing part of the cement with silica fume, using natural pozzolans in the mix or by sealing the pore system using additives in the mix or impregnating it with sulphur

Glass Fiber Reinforced Concrete is, well, pretty much exactly what it sounds like: concrete reinforced with glass fibers. As in most composite materials, the fiber elements in GFRC can be carefully oriented, or randomly distributed, in the solid matrix. The nice thing about the latter method is that you can just mix the reinforcing fibers into the bulk concrete and don’t have to pre-position
Superplasticizers, when added to fiber-reinforced concrete, can lower water: cement ratios, and improve the strength, volumetric stability and handling characteristics of the wet mix. The properties of PFRC with various fiber volume % are shown in Table 2.
CIP 24 – Synthetic Fibers for Concrete WHAT are Synthetic Fibers? Synthetic fibers specifically engineered for concrete are manufactured from man-made materials that can withstand the long-term alkaline environment of concrete. Synthetic fibers are added to concrete be-fore or during the mixing operation. The use of syn-thetic fibers at typical addition rates does not require any mix design
Mix design of steel fiber reinforced concrete (SFRC) is concerned with achieving a workability, homogeneity, durability and strength suitable for its use.
