近年来,东北地区一些小县城新建房屋的外装修,连同砖墙一起剥落,不但影响建筑物的美观,而且常伴有砸伤行人的危险。是什么原因造成的呢?我认为,根本原因是近年来许多小型砖厂不按生产工艺要求生产红砖,使红砖达不到质量要求,经不起东北严寒地区循环冻融检验所致。 In recent years, the exterior decoration of newly-built houses in some small county towns in the northeast, together with the peeling off of brick walls, not only affects the aesthetics of the buildings, but also often involves the danger of injury to pedestrians. What is the cause? I think that the basic reason is that many small brick factories have not produced red bricks in accordance with the production process requirements in recent years, making the red bricks fail to meet the quality requirements and cannot withstand the freezing and thawing tests in the severe cold regions of northeast China.
