Time, cost, and quality are critical factors in project execution, significantly impacting the construction industry. Civil engineers are particularly interested in developments that enhance these factors. The rising demand for durable and strong concrete structures, coupled with a shortage of skilled workers, has led to the creation of self-compacting concrete, which eliminates the need for vibration during compaction. This concrete type has gained popularity in industrialized nations like the U.S. and Japan due to its numerous advantages. Self-compacting concrete flows under its own gravity and incorporates superplasticizers, requiring a higher powder content to enhance durability and reduce segregation and leaching. Compared to traditional concrete, it contains less coarse aggregate, minimizing the risk of blockage when passing through reinforcement. After two decades of development, self-compacting concrete has addressed many challenges in concrete structures, especially where vibration is impractical. Its key benefits include high efficiency, resistance to separation, reduced labor costs, and accelerated construction timelines. This book examines the resistance of self-compacting concrete to alkali-silica reactions and freeze-thaw cycles, adhering to existing standards. Findings reveal a 21% decrease in resistance to alkali-silica reactions for self-compacting concrete, compared to 33% for ordinary concrete. Additionall
