- Abstract
The coal gasification slag was used as the main material to sinter ceramsite, and the sintering system of ceramsite was studied. In addition, the influence of municipal sludge dosage on the basic properties, pore structure and microscopic mechanism of ceramsite were studied. The results show that the strength of coal gasification slag ceramsite is reached to 11. 3 MPa when the preheating temperature 500 ℃ for 30 min and sintering temperature 1 100 ℃ for 15 min. The compressive strength of ceramsite is greater than 6. 5 MPa when the municipal mass content is 20% in this sintering system. Besides, the porosity and average pore diameter of ceramsite increase with the increase of sludge content, and the internal structure of ceramsite became loose, which increases the water absorption rate, reduces the apparent density, and adversely affects the strength of the ceramsite.
