About this listen

 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.
