Welcome to the Seventh International Conference on Durability of Concrete Structures (ICDCS 2022) which will be held in University of Jinan, Jinan City, Shandong, China, on Friday 20 - Sunday 22, May, 2022. The International Conference on the Durability of Concrete Structures (ICDCS) series brings together leading experts in the field of concrete durability from around the world. The aim is to discuss recent progress and latest developments in materials technology, assessment of performance both in laboratories and on site, service life concepts and reuse and recycling of construction materials and products to enable concrete constructions to be durable and sustainable. ICDCS series brings together leading experts in the field of concrete durability from around the world since its inception in 2008 and hosting the first ICDCS at Zhejiang University in 2008, since then we successfully organised ICDCS at every two years, with Hokkaido University hosting in 2010, Queen’s University Belfast in 2012, Purdue University in 2014, Shenzhen University in 2016 and the last one by University of Leeds in 2018. ICDCS series provides a unique opportunity to discuss recent progress and latest developments in materials technology, assessment of performance both in laboratories and on site, service life concepts, reuse and recycling of construction materials, and products to enable concrete constructions to be durable and sustainable.
