The shaped samples are dried naturally for 24 hours and then put into the oven at 105±5℃ for 8 hours There were no cracks on the dried brick samples, and the strength is quite good, and drying line shrinkage ratio is 1 76%
(1) Temperature gradient furnace: small samples (40x20x10mm) is fired in the temperature gradient furnace to measure the firing temperature and temperature range Firing conditions is as follow:Heating rate: ＜200℃ hrFiring cycle: 6 hoursHeat preservation:
The test was carried out on fired samples, and there was no lime bursting phenomenon occurred in the small-scale simulated test
The test was carried out on fired samples, and there was no frosting phenomenon occurred in the small-scale simulated test
(1) Sample clay has higher content of CaO, low plasticity and low drying sensitivity (2) When performing small-scale sintered bricks simulated test with 100% clay as raw material, the shaping process is rather difficult, the wet green brick strength is po
