空心微珠轻质陶粒的制备与性能
Preparation and Properties of Lightweight Ceramsite Made by Hollow Microspheres
摘要
Abstract
The lightweight ceramsite was prepared with hollow microspheres in coal gangue and green glass hollow microspheres as raw materials. After the pelletized green bodies are dried and sintered, the lightweight ceramsite was obtained. The influences of sintering temperature, holding time and glass powder content on the properties of lightweight ceramsite were investigated. The results show that the apparent density and water absorption rate of ceramsite increase gradually while the compressive strength firstly increases and then decreases with the increase of sintering temperature. When the ceramsite is sintered at 700℃, the maximum compressive strength (i.e., 200.5N) is obtained. The compressive strength of the ceramsite firstly increases and then decreases as the holding time increases. Adding glass powder can improve the compressive strength. The compressive strength increases with the increase of glass powder content. The compressive strength of ceramsite with a glass powder content of 25% (in mass fraction) sintered at 700℃ is 327.5N, which is increased by 63.3%, compared to that of ceramsite without any glass powder.关键词
