Key Issues in Properties and Application of Machine-Made Sand Self-Compacting Concrete

摘要

Based on studying properties of materials for self-compacting concrete with machine-made sand, it analyzed current application of self-compacting concrete in China. Meanwhile, key issues in self-compacting concrete with sand-made sand, such as content of rock powder, principles of mixing proportion, quality of machine-made sand, construction management, scientific research, engineering application and propaganda and promotion on application were also proposed in this paper.
