"We cannot afford to work without Kalmatron."

---Los Angeles Department of Water and Power

KALMATRON® KF-A is a patented (U.S.A. Patent 5,728,208) powder admixture to concrete mixes. KF-A provides high early strength, quick setting times, resistance to rebar corrosion and absolutely NO shrinkage cracks. KF-A is used in shotcrete, gunite, precast, cast-in-place, poured, plaster, stucco and many other kinds of applications. 100% non-toxic and safe for drinking water.

Production of bathtubs, kitchen sinks, countertops, veneers, and roof tiles with Kalmatron KF-A results in natural-looking, ceramic-strength, durable concrete products. By using KF-A, it is also possible to utilize a great variety of local raw materials as filler and aggregates, including industrial waste such as glass, wood, paper, and metal. We provide mix designs on request.
