中文摘要：

为了不破坏黄土本身的微细孔结构，进行了低温（200℃）水热合成黄土为多孔材料的研究。研究结果表明，Ca（OH）2添加量、水热合成时间对水热合成后样品的抗折强度有很大影响。样品强度增加的主要因素是托勃莫来石的生成。水热合成过程中，由于溶解，析出以及晶体生成等原因，可以产生大量微细孔，这使得控制多孔材料的孔径大小与分布成为可能。

英文摘要：

In order not to undermine the pore structure of loess,hydrothermal synthesis of porous materials from loess at low temperature（200℃） has been carried out in this paper. The results showed that Ca（OH）2 content and curing time had a great effect on flexural strength of specimens after hydrothermal synthesis. The increase in flexural strength of specimens after hydrothermal synthesis was mainly due to the formation of tobermorite. As dissolution/precipitation,crystal formation or some other faetors,a large number of pores produced during the hydrothermal process,which made it possible to control the pore size and distribution of the porous materials.
