Time, cost, and quality are critical factors in project execution that significantly impact the construction industry. The demand for concrete structures, coupled with a shortage of skilled workers, has led to the development of concrete that does not require vibration for compaction. Self-compacting concrete has gained popularity in industrial countries like the U.S. and Japan due to its numerous advantages. This concrete flows under its own gravity, utilizing superplasticizers for fluidity, while a higher powder content enhances durability and reduces segregation and leaching. Compared to ordinary concrete, self-compacting concrete has a lower coarse aggregate content, minimizing blockage risks during placement. After two decades of development, self-compacting concrete has addressed many challenges associated with concrete structures, particularly in situations where vibration is impractical. Its high efficiency, separation resistance, reduced labor and costs, and accelerated construction processes are key benefits. This book examines the resistance of self-compacting concrete to alkali-silica reactions and freeze-thaw cycles, adhering to existing standards. It compares self-compacting concrete with ordinary concrete, revealing a 21% decrease in resistance to alkali-silica reactions for the former, compared to 33% for the latter. Additionally, tests on self-compacting concrete subjected to 100 freeze-thaw cycles show an 11
