  • Concrete Fracture Models and Applications

    Concrete Fracture Models and Applications
    Nov 27 2025
    Contrasts the limitations of traditional Li1near Elastic Fracture Mechanics (LEFM) with more appropriate nonlinear fracture models, such as the cohesive crack model and the crack band model, necessary for accurately capturing concrete's softening behavior and the critical size effect. Significant attention is paid to specific contemporary methodologies, including the double-K and double-G fracture models, which provide efficient means to analyze crack initiation and unstable propagation in structural design. Furthermore, the material outlines common experimental procedures and specimen geometries, comparing the uses and advantages of the Three-Point Bending Test (TPBT), Compact Tension (CT) test, and the increasingly favored Wedge Splitting Test (WST). The document concludes with extensive acknowledgments, recognizing the large community of researchers who contributed to the development of these complex fracture criteria.

  • Concrete Framed Buildings

    Concrete Framed Buildings
    Nov 27 2025
    Provide comprehensive technical guidance for design teams tasked with selecting the optimal concrete frame and slab options for new building projects. The literature stresses that the structural selection should prioritize "best value" over minimum initial cost, factoring in crucial long-term criteria like construction speed, robustness, durability, and efficient operation. Detailed comparisons are offered for various slab types, including flat slabs and ribbed/waffle slabs, explaining their suitability based on span capabilities, service integration, and acoustic requirements. The text also strongly advocates for concrete's inherent advantages, such as its high thermal mass and long life cycle, which enhance building sustainability and reduce operating costs. Specific instruction is given on maximizing efficiency through rapid construction techniques and coordinating the placement of services, particularly in relation to post-tensioned concrete applications. Ultimately, these documents aim to ensure engineers and design teams make informed material choices that result in superior whole-life building performance.

  • Concrete In Hot Environments

    Concrete In Hot Environments
    Nov 27 2025
    A volume on modern concrete technology, offers a systematic analysis of concrete behavior and durability, particularly emphasizing performance under hot environmental conditions. It begins by detailing the chemical makeup of Portland cement, explaining how constituents like Alite and gypsum govern early-age characteristics such as hydration rates and setting times. A significant portion of the text focuses on practical challenges posed by heat, specifically the accelerated slump loss and the increased potential for defects like plastic shrinkage cracking that arise from rapid stiffening. The discussion then transitions to long-term performance, addressing complex topics such as creep, drying shrinkage, and threats to durability like sulphate attack and reinforcement corrosion. Ultimately, the text recommends precise material and mix design strategies, including cooling techniques and the use of blended cements (such as slag cement), to maintain workability and ensure long-term structural integrity.
