The research results obtained untie the end of this grant were summarized as follows ;(1) Coment board reinforced with non-asbestos fiber, which has efficient durability for practical use, has been fabricated.(2) Many characteristie factors determining frost durability of the board were found.(3) The relationship between frost durability and internal microstructure coming from forming process of the board was elucidated.(4) New analysis on frost action of porous building materials has been established.(5) The fundamental research of phase transition behavior at low temperature of water adsorbed on an internal surface of porous building materials was undertaken. And as a result, the degree of thermadynamical stability of adsorbed water on the solid surface was experimentally pointed out.(6) Reasonable test method for frost durability of porouo building anaterials has suggested.

本研究成果总结如下：(1)研制了实用高效的非石棉纤维增强混凝土板材。(2)找到了影响板材冻害耐久性的诸多特征因素。(3)阐明了板材成型过程中内部微观结构与冻害耐久性的关系。(4)对多孔建材的冻害行为进行了新的分析。(5)开展了多孔建材内表面吸附水的低温相变行为的基础性研究。提出了合理的多孔建筑材料冻害耐久性试验方法。
