REDCO II - RedcoLite Lightweight Perlite Concrete

RedcoLite Perlite Concrete

RedcoLite Concrete Aggregate is an expanded perlite of low density, meeting the requirements of ASTM C332. Portland Cement mixes using RedcoLite as the sole aggregate, or using RedcoLite combined with other aggregates have been designed to produce ultra-light concrete with dry densities from 22 lb. per cubic foot to 80 lb. per cubic foot. Comressive Strength will range between 90 and 3,000 psi. Insulation value increases dramatically as the density decreases.

The table below covers a few of the common mix designs for RedcoLite Perlite concrete. You may contact us for more mix designs. Quantities are for one sack batches with aggregate (RedcoLite) proportions expressed as a ratio of loose volumes. A 94 lb. sack of cement is presumed to be one cubic foot, loose.

Mixing Procedures

Proper mixing will assure maximum yield and uniformity. Low shear, low RPM mixers (similar to plaster mixers) are recommended for fastest uniform mixing on the jobsite. The mixing procedure should be:

1. Add all materials except RedcoLite (Cement, Water, Admix, and other aggregate, if required); mix until this slurry is fairly uniform. Two minutes will usually suffice.

2. Add all RedcoLite and mix only long enough for a uniform mix, probably 2 to 3 minutes.

Excess water and under mixing may reduce yield and workability. Over mixing may degrade RecoLite and increase concrete density.
