How Bricks Are Made and Fired
Description
Bricks are made from fired clay and come in many shapes, sizes, and colors. They are a basic building material used in construction. The brickmaking process begins with local clay or shale, which is crushed, ground, and screened to make a fine material.
Next, the refined clay is mixed with water ...

砖是由烧制黏土制成的砌筑单元,具有多种形状、尺寸和颜色。
传统上,砖块是在一个简单的木制模具中制成的,一次只能生产固定数量的砖块。
当地黏土和页岩被用于制造砖块。原料需经过破碎、研磨和筛分,以获得均匀细腻的质地。
然后将该材料与水混合,制成可塑性黏土,并通过湿塑法、干压法或半干法将其成型为砖块。
将生黏土塑造成砖块后,需进行风干处理,然后在窑中以华氏1800至2400度的高温进行焙烧,以制备适用于建筑用途的砖块。
砖块在窑中的烧制时间介于40至150小时之间。随后采取控制冷却措施,以防止砖块发生热裂。
窑内温度影响砖块的尺寸和颜色——较高的温度会导致砖块收缩更明显且颜色更深。
