石灰烧粘土水泥的颜色是随着烧粘土的颜色而变化,红色烧粘土制成的水泥也是红色,青灰色烧粘土制成的水泥也是青灰色.在江苏地区,由于习惯的关系,一般都觉得青灰色的水泥比较美观.因此,我们研究试烧青灰色石灰烧粘土水泥.在试烧的过程中,泰兴县手工业联社首先成功了,接着徐州、南京等地区也试验成功,这一方法在江苏地区已有很多地方推广.现简介如下: 制造石灰烧粘土水泥,粘土必须在摄氏600-800度间,经过8-10小时的煅烧,才能提高它的活性.煅烧粘土的方法与一般烧粘土砖的方法基本上是相同的,开始时温度应稳步上升,使粘土坯中的游离水慢慢的蒸发,当温度升到摄氏400度左右时,就可以适当
The color of lime-fired clay cement varies with the color of the burned clay. The cement made of red burnt clay is also red, and the cement made of gray-gray burnt clay is also gray-gray. In the Jiangsu region, due to the habit, it is generally felt The gray-gray cement is beautiful. Therefore, we studied the trial firing of a gray-gray lime-fired clay cement. During the trial-fired process, the Taixing County Handicrafts Co., Ltd. first succeeded, and Xuzhou, Nanjing, and other regions also successfully tested. This method is The Jiangsu region has been promoted by many localities. The current situation is as follows: To make lime-fired clay cement, the clay must be calcined at temperatures between 600 and 800 degrees Celsius for 8-10 hours in order to increase its activity. The method of calcining clay and burning clay in general The method of bricks is basically the same. At the beginning, the temperature should rise steadily, allowing the free water in the clay slab to slowly evaporate. When the temperature rises to about 400 degrees Celsius, it can be appropriate.
