方镁石的水化是轻烧氧化镁膨胀的理论基础。
The hydration of periclase in the magnesia is the theoretical basis for its expansion.
轻烧氧化镁掺量越大，水泥砂浆的膨胀率越大。
The more the magnesia replaces the cement, the greater expansion rate of the cement mortar is.
聚丙烯纤维和轻烧氧化镁双掺技术的应用，在面板混凝土的防裂中发挥了明显的作用。
The application of the technology of adding both polyacrylic fiber and lightly sintered magnesia in concrete played a remarkable role in crack control of concrete facing slabs.
夹心板主要由钢丝及轻烧氧化镁、粉煤灰或者膨胀珍珠岩，再加水泥、粘结剂、发泡剂混合搅拌发泡成一整体。
The sandwich boards are mainly mixed, foamed, and integrated with steel wires, light burning magnesium oxide, fly ash or expanded pearlite, cement, adhesives, and foaming agents.
