The signature "Creamy Effect" of KF-A on a concrete batch, with lower slump and high workability. At left is the yield of a plaster mix and at
right is the yield of a concrete mix for flat works with the same slump of 2.56" or 6.50 cm, as shown in the center image.
Both mixes are easily pumpable without clogs, and highly adhesive without sliding or shrinkage cracks.
KALMATRON® KF-A is a powder admixture to concrete mixes. KF-A provides extension of the cement gel surface by decay-hydration of the cement grains from 100 µm to 10 µm during the first 20 minutes. This increases the cementitious value and volume of the cement rock.
Complete cement hydration by KF-A makes it possible to completely replace SILICA FUME and MICROCEMENTS at a fraction of the cost.
The quality and durability of concrete depend on cement hydration. KF-A hydrates all of the cement in a concrete batch, resulting in a uniform, isotropic concrete structure. KF-A is a cost‐effective example of the transformation of any conventional concrete mix into a High Performance Concrete.
KF-A acts in four ways when added to the concrete batch:
1. As a Water Reducer during mixing and pumping
2. As a Plasticizer during transportation and placement
3. As a Shrinkage controlling and Curing Compound during setting time
4. As a Strength gainer and impermeability performing agent during hardening time;
5. As a rebar corrosion inhibitor during batching.
KF-A is safe for use in drinking water systems and food storage structures.
EXPECTED RESULTS
1. Highest volume of cement hydration results in concrete formation without curing. No curing is required.
2. Exothermic heat is lower at 30% to 50%. There are no shrinkage cracks and slab’s curling. No fibers are required.
3. The volume of the cement gel is higher by 8% to 14% per batch. No water reducer or plasticizer required.
4. Plaster is 100% water impermeable at ¾” thick and concrete is 100% impermeable starting at 2” thick. No membrane is required.
5. Early strengthening at 1-3 days at 25%. No strength gainers and excessive rebar arming is required.
7. Corrosion Inhibition meeting the requirements of ASTM C1582. After being added to concrete during batching, KF-A chemically inhibits the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete.
Concrete must be free of cracks, impermeable, and durable without excuses. This is KALMATRON® CONCRETE at the cost of conventional one.
