Kilogram for kilogram it takes half the energy to produce furnace slag cement that is needed for regular cement. Additionally, the cement industry at present relies on limestone and clay for its raw materials, turning whole hillsides into vast eyesores and using up natural resources that future generations may never see.
製造一公斤爐石水泥，所消耗的能源僅為普通水泥的一半；水泥業者大量開採石灰岩與黏土作為原料，既破壞景觀，也消耗後世子孫仍須仰賴的天然資源。
