(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 poor, which need to remind the client. The drying and firing performance of the shaped samples are good with moderate burning temperature from 980℃～1080℃.
(3) No lime bursting phenomenon occurred when proceeding small-scale simulated test.
(4) No frosting phenomenon occurred when proceeding small-scale simulated test.
