Multi-filament fibre 12 mm for screeds and concrete in general

Code: RDM.0356

Components: 1

Appearance: Fibers

READYMESH PM-120 is an auxiliary, multi-filament polypropylene micro-fibre, with CE marking, 12 mm long, suitable for the addition to cement conglomerates in general. The addition of READYMESH PM-120 to the mix counters the cracking phenomenon due to plastic shrinkage of the concrete, as well as having positive effects on the durability of the mix, resistance to frost/defrosting and resistance to knocks and overall impermeability.

Variable according to the type of work to be carried out (screeds, plasters, mortars), on average from 0.6 to 1.5 kg per cubic metre of cement or hydraulic lime based conglomerate.

Use fields

Sub-base screeds (also for radiating systems), fine casts, small pre-fabricated works, concrete floors, ballasts in cement mix and structures in concrete in general, also combined with traditional metal reinforcements.

Use method

Add the fibres to the cement conglomerate during mixing. Mix, with the drum of the cement mixing lorry at full speed, for at least one minute for each m³ of conglomerate. The dosage, based on use, is normally between 600 g/m³ and 1,5 kg/m³. The recommended dosage is 1.0 kg/m³, corresponding to a bag per metre cubed of conglomerate.
The addition of fibres could slightly modify the rheology of the cement mix. To restore original fluidity, if necessary, only use specific fluidifying additives. You are not advised to add water to the mix.
