建(jian)筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，是二水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)在(zai)一(yi)定溫(wen)(wen)度下加(jia)熱(re)脫水(shui)，并(bing)磨細制成(cheng)(cheng)的(de)(de)以β-半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)為(wei)(wei)主要組成(cheng)(cheng)的(de)(de)氣硬(ying)性膠凝(ning)材料(liao)。廣泛(fan)應用(yong)于各類石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)板、石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)砌塊粉刷石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、模型(xing)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)等石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制品(pin)(pin)。生(sheng)產(chan)β型(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)的(de)(de)原(yuan)料(liao)主要為(wei)(wei)含硫酸鈣的(de)(de)天然石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)（又稱生(sheng)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)）或(huo)含硫酸鈣的(de)(de)化工副(fu)產(chan)品(pin)(pin)和(he)磷(lin)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、氟石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)等廢渣，其化學(xue)式(shi)為(wei)(wei)CaSO4.2H2O，也(ye)稱二水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。將二水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)在(zai)不同的(de)(de)溫(wen)(wen)度下煅燒可得到不同的(de)(de)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)品(pin)(pin)種。如將二水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)在(zai)107~170℃的(de)(de)干燥條件下加(jia)熱(re)可得建(jian)筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。
