摘要
为探讨建筑材料性能对混凝土早期裂缝的影响,笔者从建筑施工过程中混凝土易发生裂缝的部位和原因进行了分析,认为材料因素是造成混凝土早期裂缝的主要原因,如水泥、骨料的质量、粉煤灰、碱骨料反应、水灰比、坍落度等因素,并针对以上原因提出了相应的预防措施,以保障建筑行业的健康发展和建筑物的质量安全.
In order to explore the effects of performance of building material on early stage concrete cracks, in this paper, the sites that easily cracked and the causes of concrete crevice during the course of construction were analyzed. It was indicated that material is the vital factor of early stage concrete cracks, such as cement, the quality of aggregate, fly-ash, alkali-aggregate reaction, water cement ratio, and slump. According to above cau- ses, the corresponding preventive measures were put forward to keep the development of the construction industry and the quality security of construction.
