Special Issue Information

Dear Colleagues,

Research on the mechanical properties of cement and concrete is essential for understanding and improving their strength, durability, and performance in various conditions. These materials are fundamental to construction processes which are associated with areas such as infrastructures, tunnels, and subsurface wellbores. The use and improvement of cement and concrete can be complex as their properties depend on curing condition, formulation, age, and application requirements. Therefore, the need for advanced methods to analyze and enhance these materials is critical. This has led to focused research on various aspects of their mechanical properties. The primary aim of this Special Issue is to explore recent the challenges and advancements associated with the study of the mechanical properties of cement and concrete. Topics of interest include, but are not limited to, the following:

  • The microstructural analysis of cementitious materials;
  • The impact of additives and admixtures;
  • The behavior of cement and concrete under different pressures and temperatures;
  • Non-destructive testing methods;
  • Environmental factors affecting curing and performance;
  • Sustainable practices in concrete production;
  • Enhancing the resilience and longevity of concrete structures;
  • Cement and concrete monitoring technology.

This study was aimed at determining the hardened and fresh properties as well as the high-temperature resistance of high-strength concrete (HSC) produced by incorporating diatomaceous earth, polypropylene, and glass fibers. CDE (calcined diatomaceous earth) was employed as a 10% cement replacement, while polypropylene and glass fibers were added separately to the mixtures at 0.2, 0.4, 0.6, 0.8, and 1.0% volumetric contents. Moreover, the mixtures without using CDE and fibers were used as references. The concrete mixtures were fabricated, followed by the determination of the fresh concrete flow, the absorption capacity, and the flexural, compressive, and splitting tensile strengths of hardened concrete. Furthermore, the specimens fabricated for the hardened concrete were exposed to temperatures of 400 °C, 500 °C, and 600 °C, and the remaining compressive strength was examined. The findings suggested that the incorporation of polypropylene and glass fibers in HSC with CDE enhanced the compressive, flexural, and splitting tensile strengths by 23.4 and 32.6%, 70.0 and 83.5%, and 18.9 and 17.9%, respectively. Moreover, the inclusion of polypropylene and glass fibers reduced the absorption of hardened concrete. Meanwhile, the inclusion of CDE lowered the strengths and increased the absorption. It was further identified that the incorporation of CDE enhanced the resistance of HSC to high temperatures, while polypropylene and glass fibers lowered the resistance. The incorporation of CDE, polypropylene, and glass fibers also lowered the flow of fresh concrete. Full article
