一、概述我国土地资源缺乏而粘土砖的生产占用了大片农田或土地,因此,用蒸压灰砂砖(以下简称灰砂砖)代替粘土砖,势在必行。邢台市使用灰砂砖的历史已有十多年,但由于人们习惯使用传统的粘土砖,对灰砂砖缺乏认识,因此,推广使用缓慢。经近几年的实践,人们发现灰砂砖比粘土砖强度高、外形尺寸规则、色泽淡雅,于是,城市多层建筑也开始采 I. Overview China’s lack of land resources and the production of clay bricks occupy a large area of ​​farmland or land. Therefore, the use of autoclaved sand-lime bricks (hereinafter referred to as sand-lime bricks) instead of clay bricks is imperative. The history of using sand-lime bricks in Xingtai City has been more than a decade, but due to people’s habit of using traditional clay bricks, there is a lack of knowledge about sand-lime bricks, so the promotion is slow. After years of practice, people have found that lime-sand bricks are stronger than clay bricks, and have a regular shape and light color. Therefore, urban multi-story buildings have also begun to pick up.
