Readymesh PS

Monofilament macro-fibre for structural spritz-beton and prefabrication

Structural polyolefin macro-fibre, high performance, for improved adherence specific for structural applications, even as a substitute for conventional steel reinforcements. Readymesh PS increases the absorption of energy of the product in case of breakage and yielding, it gives the concrete a greater resistance to the forces of traction/bending, it reduces the risk of breakage of the concrete component in the corners and edges. It also reduces the phenomenon of segregation of the concrete during the installation and it reduces the risk of corrosion of the reinforcing rods (if present) due to the reduction in cracking from plastic shrinkage. Readymesh PS are available in three different lengths: Readymesh PS-300 = 30 mm; Readymesh PS-380 = 38 mm; Readymesh PS-480 = 48 mm

    Fields of application

    It can be used where widespread structural and three-dimensional reinforcement of the conglomerate is required. It is particularly indicated in structural applications and in severe operating conditions (after static-structural calculation). The main applications, to name a few, are projected concretes (spritz-beton, shotcrete, shotcrete), mass concrete, base slabs and underpinning, structural slabs, medium and large prefabrication, etc.

    Mode of use

    In the case of prefabrication or concrete mixing plants with pre-mixer, Readymesh PS can be added directly into the mixer drum or alternatively on the conveyor belt of the aggregates. Add the product, at the desired dosage, only after you have loaded the aggregates in the mixer. It is also possible to add it directly to the fibres in the mixer truck drum, after the same has been loaded with the other components of the concrete. Mix, with the drum of the mixer truck at full speed, for at least one minute for each m³ of concrete. The dosage, depending on use, is normally included between 1 to 6 kg/m³ The recommended dosage for most structural applications is 3 kg/m³. For information only (to be verified by preliminary tests): > industrial concrete floors: 2.5 - 5 kg / m³; > screeds in wet earth: 1 - 3 kg / m³; > prefabricated elements: 3 - 6 kg / m³. The replacement of the traditional steel reinforcement by the addition of the certified structural fibres Readymesh PS can occur only with the approval of the structural engineer in charge. Do not introduce the fibres in truck mixer until you have loaded at least 40% of the aggregates!
