KRYSTALINE Add PLUS 2.5 main features

KRYSTALINE Add Plus 2.5 is a new generation high-performance admixture.

Available in predosed 1 kg water soluble bags to be added directly to the concrete mix.
Product certified by the British Board of Agrément with extremely favorable results. Agrément certificate no. 19/5612
Krystaline Add PLUS 2.5 effectively lowers the water/cement ratio by a much higher amount compared to normal crystalline admixtures.
Excellent slump retention.

Allows for removal of other admixtures such as super plasticizers, water reducers, set retarders etc., from the concrete and simply use Krystaline Add PLUS 2.5 to achieve High Durability concrete.
Waterproofs and improves the durability of concrete using hydrophilic, hydration enhancing, crystalline technology.

Concrete is a naturally porous material, with microcracks, voids, pores and capillaries that are formed mainly in the early stages of curing. The more interconnection between these holes, the more permeable the concrete is and the more prone to damage caused by the entry of water and corrosive agents. However, Krystaline Add PLUS 2.5 virtually eliminates porosity of the concrete and many of its inherent weaknesses, which increases durability.
Krystaline Add PLUS 2.5 acts by hydrophilic crystallization. It catalyzes chemical reactions between unhydrated cement particles and water, creating insoluble crystalline hydration products which fill the concrete’s capillary network. These crystal deposits become an integral part of the hydrated paste. The resulting concrete has a significantly greater ability to autogenously heal cracks and resist the penetration of water under hydrostatic pressure.

Krystaline Add PLUS 2.5 is a powder admixture that is added directly to the concrete mix in water-soluble bags. Serves to reduce water by up to 15% subject to mix design. Krystaline Add PLUS 2.5 is compatible with most super-plasticizers, it is recommended to test before mixing.
Add Krystaline Add PLUS 2.5 directly to the concrete during mixing at any time. However, the addition can affect the plastic properties of concrete. Prior testing is recommended.
