Ultralow-carbon magnesium oxide slag cement as well as preparation method and application thereof
The invention provides ultra-low carbon magnesium oxide slag cement, which is prepared from the following raw materials in percentage by weight: 36 to 95 percent of granulated blast furnace slag, 3 to 40 percent of gypsum raw material, 0.5 to 5 percent of magnesium oxide raw material, 0 to 50 percent of cement admixture and 0 to 5 percent of coagulating and strengthening component, the magnesium oxide raw material is a material taking free magnesium oxide and/or magnesium hydroxide as a main active mineral, and the sum of the free magnesium oxide and the magnesium hydroxide does not exceed 3.25% of the total weight of the raw material. The invention also provides a method for preparing the ultra-low carbon magnesium oxide slag cement and application of the ultra-low carbon magnesium oxide slag cement in preparation of concrete, mortar, cement products and grouting materials. The ultra-low carbon magnesium oxide slag cement provided by the invention is higher in hydration and hardening speed and higher in early-stage and later-stage strength.
本发明提供一种超低碳氧化镁矿渣水泥，按重量百分比计，由以下原料制成：粒化高炉矿渣36%~95%、石膏类原料3%~40%、氧化镁类原料0.5%~5%、水泥混合材0%~50%和调凝促强组分0%~5%；所述的氧化镁类原料为以游离氧化镁和/或氢氧化镁为主要活性矿物的材料，所述的游离氧化镁与氢氧化镁之和不超过所述原料总重量的3.25%。本发明还提供制备所述超低碳氧化镁矿渣水泥的方法，和所述超低碳氧化镁矿渣水泥在制备混凝土、砂浆、水泥制品、注浆材料中的应用。本发明所述的超低碳氧化镁矿渣水泥水化硬化速度更快，早期和后期强度更高。
