POLITERM® BLU FEIN READY MIX

ULTRA-LIGHTWEIGHT THERMALLY INSULATING AGGREGATE, PRE-COATED WITH E.I.A. ADDITIVE. 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 carry a higher dosage of E.I.A. additive for mixing in the truck mixer.

1 m³ (35 ft³) of mortar up to 350 kg/m³ (21.8 lb/ft³) needs 880 L (232 US gal) of aggregate (2 bags of 440 L (116 US gal)). Order of loading: water, aggregate, mix 10 minutes, cement, mix 10 minutes. Minimum pumping density 250 kg/m³ (15.6 lb/ft³). Densities from 130 to 1800 kg/m³ (8.1 to 112 lb/ft³).
