800密度等级的渣土陶粒制备及性能研究
Preparation and Performance of 800 Density Grades Muck-ceramsite
摘要
Abstract
In order to further promote the utilization of municipal wastes, this paper developed a new type of ceramic powder with different density (10-15 mm, 15-25 mm).The effects of raw material formula and firing process on the properties of the ceramic particles were investigated.The microstructure of the ceramiste particles was analyzed by the ultra-depth optical microscope and scanning electron microscope.The results show that: When the mass ratio of fly ash to fly ash is 75∶25, the preheating temperature is 500 ℃, the preheating time is 20 min, the calcination time is 15 min and the calcination temperature is 1190 ℃.10-15 mm, 15-25 mm);Macroscopic properties: 15-25 mm particle size of the dregs of ceramic, cylinder pressure intensity of 4.6 MPa, bulk density 729 kg/m3, the apparent density 1329 kg/m3, 1 h water absorption rate of 1.7%, loss on ignition of 1.4%;10-15 mm particle size of the clay ceramic, cylinder pressure of 5.2 MPa, bulk density 760 kg/m3, apparent density 1483 kg/m3, (1.6%) and loss on ignition (1.4%).The microstructures of slag soils under different grain sizes were relatively loose.The internal structure of the small particle size ceramic is more loose than the large particle size, pore size is larger.关键词
