中文摘要：

以未活化的海泡石粉末为原料,利用水热固化技术,在低温（约200℃）下固化成具有一定强度的建筑材料,并进行了吸湿和放湿性能的测试.研究表明,固化时间、固化温度以及氢氧化钙含量影响制品强度,温和条件下生成的C-S-H是强度增强的主要原因.水热固化由于海泡石和C-S-H的共同存在,提高多孔性,也大大提升了其调湿性能.

英文摘要：

The study aims at hydrothermally synthesizing sepiolite products with high strength at low temperature （-200 ℃）, and testing the humidity-regulating capacity of samples. Results show that curing time, curing temperature and Ca （OH）2 content exert influence on the strength of the solidified samples,and the strength development of specimens was found to be mainly due to the formation of C-S-H in a mild condition. Owing to the coexistence of sepiolite and C-S-H,hydrothermal synthesis develops the porosity of specimens as well as increases its humidity-regulating performance.
