装饰面砖、板工程一般在施工完毕检查时合格,但经二、三年后常出现起鼓、脱落、表面波浪形等通病。过去一般都认为是由于我国建材质量差或工人操作不良所致,但是否还有其它原因? 1983年我随公司到国外,参加了大使馆工程、国际机场大楼、银行大楼、高级公寓 Decorative bricks and boards are generally qualified when construction is completed, but after the second or third year, there are common problems such as drums, falling off, and surface waves. In the past, it was generally believed that it was caused by the poor quality of building materials in our country or the poor operation of workers. But are there any other reasons? In 1983, I went abroad with the company and participated in the embassy project, the international airport building, the bank building, and high-grade apartments.
