摘　　要：黄河淤泥烧结多孔砖的耐久性能尚待深入研究。在对黄河淤泥烧结多孔砖泛霜、石灰爆裂性能研究的基础上,对其抗冻性进行了研究。通过对3组黄河淤泥烧结多孔砖的抗冻性试验,探讨其冻融破环的机理及破环特征,并对试验结果进行分析,进而提出了一些减轻冻融破坏现象的措施,为黄河淤泥烧结多孔砖的进一步推广使用奠定了基础,也为正在编制的《黄河淤泥多孔砖》产品标准提供试验数据及技术支持。A further study on durability of Yellow River silt sintered cellular brick is needed. Based on the research of floating hoarfrost and lime burst of Yellow River silt sintered cellular brick, its frost resistance has been studied. Through test of frost resistance on three groups of Yellow River silt sintered cellular brick, the fracture mechanism and failure feature of freezing and thawing have been explored, the test results analyzed and put forward some measures to reduce the failure phenomenon of freezing and thawing in order to lay a foundation for wide use of the Yellow River silt sintered cellular brick,and meanwhile provide trial data and technical support for the product standard ＂The Yellow River Silt Cellular Brick＂ which is under compile.
