UNHYDRATED CEMENT: A PROBLEM IN CONCRETE

Unhydrated cement grains constitute a major problem in new concrete construction. It is estimated that unhydrated cement grains make up about 8-10% of the total concrete volume. However, Kalmatron® works on the unhydrated cement grains before crystallization and dissolves them. Plus, the water/cement ratio can be decreased from 300 lbs. (37 gal.) of water per cubic yd. of concrete, to 270 lbs. (33 gal.) of water per cu. yd., which is an important reduction for concrete mix.

NOT A FILLER

There are numerous concrete additives available on the market today and almost all of them are some type of filler. It is a well-known fact that over time, concrete repels foreign inclusions. Kalmatron® is NOT a filler; NOT a polymer; NOT a plasticizer; NOT an organic mineral; NOT pozzolanic; and, does NOT contain chloride. Kalmatron® is an inorganic composition which is chemically similar to cement. Kalmatron® diffuses into the concrete in a way that creates one homogeneous mass. Kalmatron® is compatible with concrete. On the molecular level, there is an affinity between Kalmatron® and concrete.

COMPOSITION

Let's take a look at what changes take place in concrete with the addition of Kalmatron®. Depending upon the ratio of Kalmatron® to cement in the concrete mix, either flexural strength can be increased dramatically, or compression strength can be increased as follows:

Normal Density of concrete is around 125 lbs. per cu. ft. Kalmatron® increases this density to 150 lbs. per cu. ft. economically. This is a substantial increase in the most important factor in concrete strength.
Resistance to Corrosion of the rebar increases up to 100% in water, sea water, and sewage. This is mainly due to the density of the concrete, however, it is also due to the formation of a .006mm oxide film from the Kalmatron® solution. Chloride and sulfate penetration to the rebar is effectively stopped.
When used in pure form, as a 3mm - 5mm facing, Kalmatron® is Impermeable to Liquids up to 14 atms. It is also impermeable when 10-15 lbs. of Kalmatron® is mixed with 1 cu. yd. of concrete, given the following: that the mass of the concrete is large enough to become impermeable, such as heavy construction and bridge construction. Again, the recommended concrete mix ratio is 10-15 lbs. of Kalmatron® to 1 cu. yd. of concrete, or 5-10 kg. of Kalmatron® to 1 cu. m. of concrete.
Flexural Strength increases by 15 to 20%!!! Most additives on the market increase flexural strength by 5 to 10%.
Resistance to Rupture is extremely important when building bridges and dams. Kalmatron® increases this resistance by 60%.
Compression Strength stays inversely proportionate to flexural strength. The cement grains are completely hydrated, no voids, and less water is used in the concrete mix. Kalmatron® increases the compression strength by 20 to 25%.
Kalmatron® increases Freeze and Thaw Resistance by 35%. This is a definite advantage to contractors who work on projects in colder climates or during winter seasons.
Normal Shrinkage in concrete is .5 to .2%. Kalmatron® reduces shrinkage to .015%, which is a reduction of 66%, which allows for higher stability.
