砂(sha)巖(yan)(yan)壁畫的泥砂(sha)巖(yan)(yan)還具有(you)類似塑(su)(su)料的塑(su)(su)變性(xing),更適合雕(diao)刻和(he)切出10mm厚(hou)的薄板,關于砂(sha)巖(yan)(yan)輕微的塑(su)(su)變性(xing),現普遍認為是SiO2之間分子聯結,卻又未(wei)形(xing)成結塊的緣(yuan)故(gu)。砂(sha)巖(yan)(yan)的吸(xi)(xi)水(shui)率很(hen)大,一些品種(zhong)(zhong)(zhong)幾乎是將水(shui)倒(dao)上即滲(shen)入(ru)石材內,砂(sha)巖(yan)(yan)因其內部構造(zao)空隙率大的特(te)性(xing),都有(you)吸(xi)(xi)聲(sheng)、吸(xi)(xi)潮、防火、亞光的特(te)性(xing),這種(zhong)(zhong)(zhong)特(te)性(xing)的品種(zhong)(zhong)(zhong)裝飾到具有(you)吸(xi)(xi)聲(sheng)要求(qiu)的影(ying)劇院、體育館、飯店(dian)等公共場所效果十分理(li)想,甚至可省去(qu)吸(xi)(xi)聲(sheng)板和(he)拉毛墻。
