POLITERM® BLU FEIN READY MIX
PRE-ADDITIVATED THERMAL INSULATING ULTRA-LIGHTWEIGHT AGGREGATE. BEAD Ø ≤ 2 MM
POLITERM® BLU FEIN READY MIX is the version of POLITERM® BLU FEIN designed for concrete batching plants: the lightweight concrete is prepared in a truck mixer and pumped to the floor with a concrete pump, for large sites and large surfaces.
It is made of EPS beads coated with E.I.A. additive: the additive makes the beads mix perfectly with cement, stops them floating and spreads them evenly through the mix, at low and high densities alike. The result is a lightweight concrete that does not settle, does not shrink and does not crack. It is the only RAL-certified aggregate. The beads have a higher degree of additivation for mixing in the truck mixer.
1 m3 of mortar up to 350 kg/m3 needs 880 L of aggregate (2 bags of 440 L). Order of loading: water, aggregate, mix 10 minutes, cement, mix 10 minutes. Minimum pumping density 250 kg/m3. Densities from 130 to 1800 kg/m3.
