INTEGRAL WATERPROOFING CEMENTITIOUS ADMIXTURE BY CRYSTALLIZATION

DESCRIPTION:
TECMA ADMIX CRYSTAL is a cementitious admixture specially formulated for improving the waterproofing of concrete. The active chemicals that contains will produce a catalytic reaction inside the concrete that will form a non soluble crystalline material that precipitates inside the pores and capillaries of the concrete structure, sealing them against the pass of water and originating a phenomenon of densification and waterproofing in all the concrete mass. This way concrete is permanently waterproofed for positive and negative water pressures, even for high pressures

PROCESS OF CRYSTALIZATION GENERATED BY TECMA ADMIX CRISTAL:
The active chemicals of TECMA ADMIX CRYSTAL, according to the Fick Laws, and as a consequence of Brownian movements and osmotic processes, diffuse through the solid and liquid phases inside the concrete structure and, in the presence of water, react with the by products of the cement hydration generating a series of catalytic reactions that culminate with the formation of non soluble crystals inside the pores and capillaries of the concrete, sealing them against the water penetration. Due to the continuous production of crystals the concrete becomes more and more dense and this way blocks the pass of water and prevents the pass of noxious substances. This way the concrete gets its waterproofing properties and at the same time allows the pass of water vapour (concrete breathing). The formed crystals will stay inside the concrete and the crystallization process will continue provided there is presence of water.
The cracks that will be produced in the concrete in the future will be sealed if they have a maximum width of 0.4 mm. (self healing property).

APPLICATION FIELD:
TECMA ADMIX CRYSTAL can be used for most of the concrete structures that are expected to be in contact with water. It is recommended, among others, for:
* Pre-cast structures
* Tunnels and galleries
* Bridges
* Potable water tanks
* Waste water treatment plants
* Silos
* Marine or coastal structures
* Dams
* Canals
* Basement walls and floors
* Parking structures
* Ponds and swimming pools
