Realistic minimum requirements

Production of high-performance concretes

High-performance concrete (HPC) with compressive strengths in excess of 65 N/mm2 is becoming increasingly important in state-of-the-art structural engineering projects to improve the characteristics of buildings as a result of the associated short pouring times for components with demanding load-bearing specifications. HPCs are high-strength concretes whose resistance to external chemical or mechanical actions is essentially determined by their particularly dense and solid structure. This trend reflects the fact that, in the meantime, concrete durability has become at least as important as...
