摘　　要：目前,混凝土和钢筋材料在我国建筑工程施工中得到了广泛应用,高性能的轻质原材料为混凝土结构和钢筋优化起到了很大的帮助。混凝土具有超强的抗压能力,但其伸缩能力较差,容易出现裂缝等问题。本文将对混凝土开裂原因进行科学分析,并提出有效应对措施,希望可以提高混凝土伸缩性能。At present, concrete and steel materials had been widely used in construction engineering in China, and high-performance lightweight raw materials had greatly helped the optimization of concrete and structural steel. Concrete had superior pressure resistance, but its expansion ability was poor, and it was prone to cracks and other problems. In this paper, the causes of concrete cracking were analyzed scientifically, and effective countermeasures were put forward, hoping to improve the expansion performance of concrete.
