Outline of Final Research Achievements

In order to achieve value creation as a resource of volcanic ash, energy saving and improvement of comfort of living environment, Wet blast building materials as interior finish building materials were examined.
As a result, it was found that formulation satisfying water: volcanic ash = 1: 4 (volume ratio) and 70 to 90 mm (JASS 15 M-103 flow) is optimum. Moreover, it was confirmed that the test piece satisfied the humidity conditioning performance evaluation standard. In addition, it was found that the acid decomposition and the heat foaming treatment of the volcanic ash promoted the porosification, and improvement of the humidity conditioning performance could be expected.
