以辽南含MgO和CaO的天然矿物原料合成优质的MgO CaO砂 .经煮沸法水化试验表明 :在混合物料时配入TiO2 添加剂或在烧成后以有机硅溶液涂覆表面 ,均能明显提高MgO CaO砂的抗水化性能 .
The high quality MgO CaO sand was synthesized from natural mineral raw materials containing MgO and CaO in southern Liaoning.The hydration test by boiling method showed that when the mixed materials were mixed with TiO2 additives or coated with silicone solution after firing, Improve the hydration resistance of MgO CaO sand.
