Kalziumsilikatplatte und Verfahren zu ihrer Herstellung

摘要

A calcium silicate board according to the present invention contains a calcium silicate hydrate crystal matrix, anhydrous calcium sulfate (II), reinforcing fibers, and a carbonate substance which decomposes at 700 to 850 DEG C, wherein the content of the carbonate substance is 5 to 30 wt%. The calcium silicate board excels in fire resistance with an aeration rate of 1.5 x 10<-5> ml.cm/sec.cm<2>.cm H2O or more and excels in non-combustibility.
