KALMATRON® KF-G is a liquid spray for rehabilitation of degraded concrete rheology.
KF-G represents a new concept in concrete rehabilitation technology and became highly popular because of its effective performance and simplicity of application. In most cases, after KF-G is applied to the damaged area there is no need for it to be covered with any additional layer.
DESCRIPTION OF KF-G
White powder with strong specific smell. After application the smell disappears.
BENEFITS
- Simple application by spray, soaking or injection of aged/damaged concrete structure.
- Fast increase in concrete density by 10% and compressive strength by 20% on the third day.
- Works for any level of damage. In fact, the worse the damage, the better KF-G performs.
- Can be used as a curing compound for a new concrete application after false set, shrinkage or exothermic cracks, efflorescence, etc.
USES OF KF-G
The KF-G remedial-protective coating on deteriorated concrete or masonry prevents the structure from further corrosion while upgrading superficial compressive strength and impermeability to liquids and gases. However, the original structure under that protection is still intrinsically weak. Therefore, before the KF-G coating is applied to the surface, the structure itself should be reenforced by rehabilitation of concrete rheology.
It is common knowledge that cracks less than 3 mm in width are not repairable at all. The total volume occupied by micro-cracks is much larger than the total volume of repairable cracks. These micro-cracks are the real source of the rheological aging of concrete. KF-G actually heals these micro-cracks and increases compressive strength by 30% to 50% after 28 days.
APPLICATION
- Mix KF-G powder with water at the rate of 250 grams to 300 grams per 1 Liter.
- The concrete surface should be cleaned from paint, grease, and any other coatings.
- For economy of application, make sure that the moistness of the concrete surface is around 6%.
- Apply KF-G by any spray device, or submerge concrete for soaking, or inject into the opened void.
- A properly cured concrete surface can be recognized by its darker color, even after drying.
- If it is required that the concrete be uniformly cured, apply KF-B or KF-F layers.
