Mapefibre NS12 are 100% virgin mono-filament polypropylene fibres which are resistant to alkalis and which do not absorb water. They have been specially developed to reduce the formation of cracks induced by hygrometric shrinkage of the concrete at the fresh and hardened stages. The special “mono-filament” formation makes their distribution and position within the concrete mix easier, so that they are distributed uniformly, to create a particularly strong matrix which is resistant to the stresses induced by the setting and hardening process.
The normal dosage of Mapefibre NS12 is 600 g/m³, usually added to the concrete. Higher dosage can be used for special applications such as shotcrete or fire resistance
