加气混凝土应用中存在的问题与对策研究

加气混凝土作为一种新型的墙体填充材料，具有容重小、强度低、吸水率高、收缩性大等优点．目前，由于工程应用中存在空鼓、开裂、剥落和墙体收缩裂缝等施工质量问题，在很大程度上限制了加气混凝土材料的发展与应用．为此，应采取提高混凝土的表面性能，加强砂浆与加气混凝土的粘结等施工措施加以解决．

Study of the Problems and Countermeasures in the Application of Aero-crete

As a new type of wall-filling material, aero- cr ete has advantages as small capacity and weight, low intensity, high water-absor bing rate and large contractivity, etc. At present, the quality problems in cons truction such as inside hollow, crack, peel off and contraction have largely lim ited the application and development of aero-crete. filler materials, ae rated concrete has the priorities of small density, low strength, good absorptio n of water and great contrasting. Nowadays, because of constructing quality prob lems such as hollowing, cracking, pilling and contrasting, it, to a great extent , limits the development and application in engineering. This paper analyzes and studies these problems and brings out relevant technical measures.
