我国国民经济的高速增长,带动了建筑业的快速、持续的发展。面混凝土因其取材广泛,价格低廉,抗压强度高,可浇注成各种形状,并且耐火性好,不易风化,养护费用低,成为当今世界建筑结构中使用最广泛的建筑材料之一。而随着商品混凝土的诞生,由于其施工方便快捷,性能稳定,质量可靠,劳动强度低,生产效率高,同时又可减少噪音,保护环境等综合优点,更是把混凝土推向了一个顶峰。而混凝土楼板的裂缝是混凝土结构最常见的、也是最普遍的现象之一,这是不是一种质量缺陷?对房屋结构的安全有无影响?应如何避免和采取什么比较有效的补救措施?
The rapid growth of our national economy has led to the rapid and sustained development of the construction industry. Concrete because of its wide range of materials, low prices, high compressive strength, can be poured into a variety of shapes, and good fire resistance, easy weathering, low maintenance costs, become the world's building structure used in one of the most widely used building materials. With the birth of commercial concrete, concrete is pushed to a peak due to its advantages of convenient and quick construction, stable performance, reliable quality, low labor intensity, high production efficiency, low noise and environmental protection at the same time. The concrete floor cracks are the most common concrete structures, but also one of the most common phenomenon, which is not a quality defect? Has no effect on the safety of the structure of the house? How to avoid and take more effective remedial measures?
