A flowable and cohesive ultra-high performance cementitious (UHPC) mix that possesses superior mechanical strengths and stiffness.

NaX® Q135-F

NaX® Q135-F s supplied as a ready to use, cement-based fibre-reinforced, dry powder system. On mixing with controlled amount of potable water, it produces a flowable, cohesive ultra-high performance cementitious (UHPC) mix, which develops high compressive strength in a short period of time. With proper curing, the hardened product has a unique combination of superior technical characteristics including ductility, strength, and durability, while providing highly mouldable high-quality surface aspect.

NaX® Q135-F possesses superior mechanical strengths and stiffness with higher cracking resistance, compared to high-performance concrete (HPC). Unlike HPC, which is weak in tension with no ductility, the product is designed for high tensile strength and possesses tensile ductility with stain hardening behavior, such that the ultimate strength is higher than the plain material strength (first-crack strength). This enables traditional volumes of reinforcing steel bars to be reduced, or in some cases, eliminating them altogether. Furthermore, the UHPC mix is designed for good flowability with high inherent cohesiveness to facilitate material placement in narrow formworks without segregation, enabling production of thin shell structure.

NaX® Q135-F  NaX® Q135-F is based upon an advanced nano-engineered binder technology, which is composed of special blends of Portland cements, pozzolan cements and special cements, to produce a high quality structural cementitious material.

NaX® Q135-F is chloride-free, shrinkage-compensated and exhibits low water permeability and high resistance to aggressive ion penetration.
