摘要
传统垃圾覆盖材料难以满足目前生活垃圾处理的需要,通过对粉煤灰-石灰-硫酸盐胶凝体系的研究,开发了新型垃圾覆盖材料,并测定了其相关性能。结果表明,以粉煤灰-石灰-煅烧石膏胶凝体系作为覆盖材料对小城镇的生活垃圾进行处理是一种有效的方法,其早期强度高,整体性优异,长期强度持续发展,抗渗透能力强,收缩性满足要求,并具有良好的环境协调性。
The traditional waste cover materials can hardly meet the current demands of domestic refuse. A new waste covering material, which is based on fly ash-lime-sulfate cementitious system, is proposed, and the strength, water penetration assistance, shrinkage and pH value of the covering material and traditional soil are investigated and compared. The results show that it is effective to dispose of the municipal solid waste（MSW） in small towns when using the new covering material. In addition, it performes a series of excellent properties, such as higher early strength, well integrity, lower shrinkage, sustained long-term strength development, strong anti-permeability.
