| Ducorit® |
|
Densit has developed a portfolio of non-shrinking UHPC materials specifically designed for Oil and Gas Industry applications.
The Ducorit® range of UHPC materials exhibit extreme mechanical properties, often surpassing material requirements in engineering designs.
Important properties of Ducorit® UHPC materials include:
• Extremely high strength and stiffness
• High early strength - 50% within 24 hours at 20C
• Low heat of hydration
• Ultra high bond between Ducorit® and steel - minimal shrinkage
• Unique fatigue strenght - 50 times that of normal concrete
• High viscosity and inner cohesion prevent "washing out" of particles, separation or micture with water when cast underwater
Fibre reinforcement
Steel fibres can be incorporated into Ducorit® UHPC materials to increase the tensile and bending strength, leading to higher ductility and fracture energy.
Ducorit®
The core of the Ducorit® products is the unique ultra high strength Densit® Binder. The different properties of Ducorit® S1, Ducorit® S5, Ducorit® D1 and Ducorit® D4 are obtained by adding aggregates such as quartz sand or bauxite. Datasheet
Installation
Ducorit® is mixed and pumped from the platform or workboat through flexible hoses, into the specimen to be cast either above or below sea level.
Pile sleeve connections, jacket leg/pile and conductor casing annuli can all be cast from 5 mm upwards, together with all sizes of members, braces and jacket legs.
Installation can be carried out without disruption to oil and gas production.
Assured quality
Ducorit® products are manufactured under strict supervision and quality inspected in accordance with Densit ISO 9001:2000 certified by Lloyd’s Register Quality Assurance.
