<P>PROBLEM TO BE SOLVED: To provide a functional building material which has excellent moisture absorbing and releasing characteristics, is excellent in adsorbability of VOC, malodorous components or the like and also has a function to make harmless these adsorbed materials, and has a performance preventing pollution of the air in the room over a long period of time and keeping comfortable environment. <P>SOLUTION: The functional building material is composed of calcium silicate hydrate having a structure with fine pores which can be obtained by aging an inorganic formed product that is obtained by forming a raw material containing diatomaceous earth of 30-75 mass% at a temperature of 150-200°C and under pressure of 470-1,560 kPa. Preferably in the functional building material, the calcium silicate hydrate having a structure with fine pores is one that has fine pores with a pore size of 2-200 nm and has a moisture content of 2-20 mass%, and that contains free weakly alkaline water other than the bound water of the calcium silicate inside the fine pores. <P>COPYRIGHT: (C)2009,JPO&INPIT |
