摘　　要：本文对淤泥制备陶粒和烧结砖的研究进行了综述。结果表明,采用淤泥制备陶粒和烧结砖,虽然在烧结过程消耗大量的能源,但可以有效实现淤泥的资源化、降低淤泥处置不当对环境造成的二次污染。选用合适的焙烧温度能够显著改善烧结制品强度降低其吸水率。通过掺加粉煤灰、煤渣等瘠性料能够有效降低淤泥塑性指数,降低坯体因干燥引起的收缩,提高淤泥烧结制品力学性能。This paper reviews the research of silt to prepare ceramsite and sintered brick.The results indicate that using silt to prepare ceramsite and sintered brick can consume a lot of energy in sintering process,but can realize the recycling of silt and reduce the secondary pollution caused by mishandling of silt.Suitable calcination temperture can significantly improve the strength of sintering products and decrease the water absorption.Mixed with poor materials such as fly ash,coal cinder can reduce the mud plasticity index effectively,reduce the shrinkage of green body caused by desiccation,improve the mechanical properties of silt sintering products.
