ACI SP-25:1971 PDF Download

ACI SP-25:1971 is a comprehensive standard that delves into various aspects of how temperature impacts concrete structures. The standard begins by reviewing existing literature on the effects of sustained high temperatures. It then proceeds to present new research findings on the compressive strength of concrete when exposed to temperatures as high as 1600 F.

One important application covered in this standard is the design of prestressed concrete reactor vessels, with particular emphasis on temperatures ranging from 35 to 775 F. The publication provides valuable information that can be used to ensure the structural integrity of such vessels under these thermal conditions.

Furthermore, the document also addresses the design considerations for mass concrete dams, offering insights into temperature-related challenges and how they can be overcome. Another topic covered is the impact of temperature differentials on slabs, including both laboratory and field studies that explore this phenomenon.

Additionally, the standard highlights the influence of temperature on the curing process of concrete and discusses strategies for concrete construction in hot climates. It also evaluates the effects of water-reducing admixtures on temperature rise in mass concrete.

Lastly, ACI SP-25:1971 introduces an innovative approach to apply temperature changes to mechanically loaded structural models using thermoelectric modules. This novel technique provides a valuable tool for studying the interaction between temperature and mechanical loading in concrete structures.
