  • Self-prestressed reinforced concrete elements
    Patent number: 10604449
    Abstract: The present invention relates to improved concrete elements, particularly to self-prestressed, high-performance concrete elements (SP-HPC elements); to cementitious compositions suitable, for producing such concrete elements; to methods of manufacturing such concrete elements and such cementitious compositions; to the use of specific components in concrete elements and cementitious mixtures. The compositions and elements described herein comprise an effective amount of expansive agents in combination with superabsorbent polymers (SAP) and shrinkage reducing admixtures (SRA), and optional further components as defined in the claims. The present invention further provides for improved tendons, suitable for SP-HPC elements.
    Type: Grant

  • Fire resistant concrete
    Patent number: 9353006
    Abstract: The present invention relates to improved concrete elements, particularly to high-performance self-compacting concrete (HP-SCC); to cementitious compositions suitable for producing such concrete elements; to methods of manufacturing such concrete elements and such cementitious compositions; to the use of specific additives in concrete elements and cementitious mixtures. The inventive compositions comprise an effective amount of polymer fibers and of hydrogels. The inventive concrete elements show improved fire resistance, particularly towards explosive spalling.
