**Preface to "Advances in Sustainable Concrete System"**

Concrete is the most widely used construction material in the world, and is typically produced using Portland cement (PC) as the binder. The mass of PC used in concrete construction represents a critical environmental issue, due to the high emissions of carbon dioxide gas during its manufacture from the calcination of limestone and the combustion of fossil fuel. On the other hand, the rising demands to reduce the cost of binders in concrete necessitate the search for an alternative source of PC. This book aims to select current advanced concrete studies on environmentally friendly, cost-effective concretes and waste recycling. The relevant research focuses on, but is not limited to, the properties, evaluation, novel manufacturing/experimental techniques, analytical methods, microstructure, modeling, design, production, and practical applications of new binders/aggregates in concrete, and their behaviors in the concrete structures of in situ performance, renovation, maintenance, recycling, durability, and sustainability.

This reprint, edited by Yifeng Ling, Chuanqing Fu, Peng Zhang, and Peter Taylor, will be of interest to scholars, engineers, and government agencies in the relevant fields. The Guest Editors would like to express their acknowledgement to all authors of the papers published in the Special Issue entitled "Advances in Sustainable Concrete System".
