Qwix® is a mineral additive used with Portland cement concrete mixes to enhance the physical properties and the chemical durability related properties.
Since Qwix® is a concentrated form of Ultimax® Cement, it carries most of the properties of the cement with additional flexibility. Concrete mixed with Qwix® has low shrinkage, low expansion and low permeability.
Qwix® is cementitious Ultimax® powder used to convert all types of Portland cement in rapid hardening and very rapid hardening cement. This enhancing powder can be mixed at different percentages to accommodate any early strength gain needs.
Low shrinkage
Low expansion
Low permeability
Qwix® has been used successfully in California by Caltrans to replace freeway damaged pavement slabs. The concrete developed more than 500 psi flex strength in three hours after finish with more than 90 minutes working time.
