ACI SP-47:1975 PDF Download

ACI SP-47:1975 is a standard that focuses on the durability of concrete and its response to attack by aggressive elements. The standard consists of a collection of 17 papers that cover various aspects related to concrete durability, including freeze-thaw problems, performance in seawater, and sulfate attack. The aim of these papers is to improve our understanding of how concrete withstands environmental factors and to provide guidance on ensuring the durability of concrete structures.

The papers included in the standard address different topics such as freezing effects in concrete, dimensional changes due to slow cooling and warming, deicer scaling mechanisms, moisture distribution in concrete bridge decks and pavements, and the long-term durability of concrete in different applications. Additionally, the standard covers the influence of hot saline and distilled waters on concrete, as well as combating sulfate attack in concrete construction.

The standard emphasizes that the durability of concrete is of utmost importance for its successful performance. It highlights the need for understanding the mechanisms of deterioration, developing appropriate remedial actions, and sharing field experiences to advance knowledge in the field of concrete durability. By addressing these issues, the standard aims to contribute to the improvement of concrete durability against various aggressive elements in different environments.
