黑龙江省牡丹江地区有着藏量丰富、质地优良的页岩原料。去年以来,牡丹江市建筑科学技术研究所在兄弟单位的协助下,开展了页岩陶粒的研制工作,他们提出建筑材料要向山区要原料,不占用农田。经过反复试验,已烧制成功松散容重为450～500公斤/米~3、颗粒容重为800～900公斤/米~3、颗粒容器强度(压入4厘米)为60～75公斤/厘米~2的膨胀页岩陶粒,利用这种陶粒可以配制各种用途的轻质混凝土。 The Mudanjiang region of Heilongjiang Province has abundant shale material with excellent texture. Since last year, the Mudanjiang Institute of Building Science and Technology undertook the research and development of shale ceramsites with the help of their brothers. They proposed that building materials must be raw materials in the mountainous areas and do not occupy farmland. After repeated trials, the loose bulk density has been successfully sintered to 450-500 kg/m~3, the particle weight is 800 to 900 kg/m~3, and the particle container strength (pressed into 4 cm) is 60 to 75 kg/cm~2. The expanded shale ceramsite can be used to prepare lightweight concrete for various purposes.
