INTERBETON, drawing on decades of expertise and a strategic focus on innovation, has developed OPTIMA—an advanced Self-Compacting Concrete (SCC) that redefines construction quality and contemporary architecture. Thanks to its outstanding rheological behaviour, OPTIMA flows and compacts without vibration, completely fills even the most complex formwork and reinforcement cages, delivers high-precision, high-aesthetic structures with a smooth, dynamic finish and distinctive sheen. It is the ideal solution for projects requiring high mechanical performance and refined architectural expression.
OPTIMA brings technological excellence and architectural freedom together in a single material. It offers reliable casting, long-term durability and high surface quality. OPTIMA is the evolution of structural concrete that reduces errors, extends service life and simplifies site operations, making construction safer, more sustainable and more efficient than ever.
The technical properties of OPTIMA—such as high compressive strength and elastic modulus—support ambitious structural and architectural systems, including space frames, slender elements, and complex expressive structures, that OPTIMA can serve better than any conventional structural material.
• Minimum compressive strength class: ≥ C35/45
• Self-compacting behaviour:
– Completely fills formwork and surrounds reinforcement without vibration
– Eliminates the risk of voids, honeycombing, and paste–aggregate segregation
• Enhanced durability:
– Optimised mix design and perfect consolidation improve resistance to CO₂ and chloride ingress over time
– Improved corrosion protection and delayed onset of reinforcement attack
• Reflectance indices available, depending on mix design and locally available materials
• High elastic modulus – ideal for complex, demanding structural and architectural systems
• Stable rheology for surfaces with distinctive smoothness and sheen
• High pumpability
• Excellent workability with slump flow ≥ 650 mm
• Full compatibility with reinforcement steel B500C
• Rheological properties maintained for ≥ 90 minutes
The sustainability of OPTIMA is measured in tangible results—in energy saved, time saved, and cost reduced across the entire life cycle of the project.
• Casting without vibration eliminates the use of compaction machinery and unnecessary operations, significantly reducing energy consumption and CO₂ emissions during concreting.
• The simplified process enables faster on-site progress with fewer crews, reduced noise, and a cleaner working environment. As a result, projects are delivered more quickly, at lower construction cost and with greater accuracy.
• Perfect consolidation and homogeneity prevent defects, cracking and rework, dramatically reducing the need for surface finishing or repairs over the structure’s lifespan.
• This translates into lower maintenance and total ownership cost (TCO) and more resilient structures that maintain their value over time.
Through its state-of-the-art ready-mix concrete plant located within the Metropolitan Park, INTERBETON supplies a substantial part of the works being carried out at The Ellinikon. These include residential developments, such as The Cove Residences, The Cove Villas, the Riviera Tower, and the Little Athens neighborhood.
