Readymesh PW-120 is an auxiliary fibrillated polypropylene micro-fibre, with a length of 12 mm, suitable for adding concrete in general. The addition of Readymesh PW-120 to the mixture allows for preventing the phenomenon of cracking from plastic shrinkage of the concrete, as well as having positive effects as regards the ductility of the mixture, the resistance to freezing/thawing, the shock resistance and overall watertightness.
A calculated evaluation of the type of steel is necessary, in accordance to the compound that will be used on the mould, so as to compensate the effects that they can have, and also to permit more longevity of the mould itself.
