An extremely high early strength grout specially developed as a ready to use silo-based cementitious offshore wind energy grout, certified under DNV Type Approval Certification program.
NaX® Q110-E is certified by DNV through a Type Approval Certification (TAC) program as a ready to use silo-based cementitious offshore wind grout. On mixing with controlled amount of potable water, it produces a flowable, cohesive and impermeable ultra-high performance cementitious (UHPC) grout, which develops high compressive strength in extreme short period of time under low temperature environment. At 28-day, the product has high compressive strength exceeding 125 MPa and E-modulus of more than 40 GPa.
NaX® Q110-E exhibit excellent flowability with high inherent cohesiveness and anti-washout property and can be easily pumped into structures with narrow constrictions, filling of annulus in pipe-in-pipe systems or hollow sections, typically found in offshore wind foundation system like monopiles, tripods and jacket structures. Early-age cycling (EAC) test shows no detrimental effect on compressive strength development, nor any instability such as segregation or sedimentation of components.
NaX® Q110-E exhibits a low water permeability and high resistance to aggressive ion penetration. With a high pH value, the product provides structural corrosion protection and its shrinkage compensated design creates both a small early age expansion and long-time volume stability.
NaX® Q110-E 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® Q110-E has high flexibility to installation methods as it can be transported and applied, either by silo system or bulk FIBC bags.
