    Cracking of concrete at early ages, that may affect the structure durability and even its safety, can be simulated by means of models based on the concepts of degree of hydration and equivalent age, which require the ...
  • Comportamiento a tempranas edades de elementos de hormigón con restricción externa total 

    Crespo Garibay, María Delia; Molins i Borrell, Climent; Marí Bernat, Antonio Ricardo (2011)
    Conference report
    Restricted access - publisher's policy
    Durante las primeras edades del hormigón se producen deformaciones termo-higrométricas las cuales, si son restringidas, sobre todo por coacciones externas, producen tracciones que pueden fisurar el hormigón. Un ejemplo ...

    En esta ponencia se analiza el efecto del curado térmico sobre la evolución de las temperaturas, velocidades de calentamiento y enfriamiento, tensiones y resistencias de las dovelas de hormigón para revestimiento de túneles, ...
  • Numerical simulation since early ages of the RG8 beam test from concrack benchmark by means of a 3D fibre frame model 

    Crespo Garibay, María Delia; Ferreira, Denise; Bairán García, Jesús Miguel; Marí Bernat, Antonio Ricardo (International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM), 2016)
