日本农业省农技研究所和日本东武化学公司最近合作研究出一种使用土和氧化镁制作建筑材料的新技术。用这种技术生产的建材的坚硬度与砼一样，并具有环保作用。 据悉，这一新技术应用了氧化镁与水分相结合而生成凝胶状氢氧化镁的现象。氢氧化镁与土壤里的磷酸及二氧化碳发生反应
The Agricultural Research Institute of the Japanese Ministry of Agriculture and Japan’s Tobu Chemical Co., Ltd. have recently cooperated to develop a new technology for the use of earth and magnesia to make building materials. The building materials produced using this technique have the same hardness as that of cerium and are environmentally friendly. It is reported that this new technology uses the combination of magnesium oxide and moisture to generate gelatinous magnesium hydroxide. Magnesium hydroxide reacts with phosphoric acid and carbon dioxide in soil
