High-toughness super sulfate cement and preparation method thereof
The invention relates to a high-toughness super sulfate cement and a preparation method thereof, and belongs to the technical field of building materials. According to the invention, the defects in the prior art are mainly overcome; the invention provides a high-strength, high-toughness and high-durability high-toughness super sulfate cement and a preparation method thereof. The high-strength, high-toughness and high-durability high-toughness super sulfate cement is prepared from the following components in percentage by weight: 65 to 90 percent of mineral slag, 10 to 25 percent of gypsum, 1 to 15 percent of an excitant, 1 to 10 percent of an admixture, 0 to 3 percent of fiber and 0 to 1 percent of a thickening time control type water reducing agent. The sulfate corrosion resistance of thehigh-toughness super sulfate cement prepared by the invention is about 1.2 times and 1.5 times that of super sulfate cement and ordinary cement concrete; the flexural strength of the high-toughness super sulfate cement is about 3 times and 3.5 times of that of super sulfate cement and ordinary cement concrete, the bending deflection of the high-toughness super sulfate cement is about 40 times and50 times of that of super sulfate cement and ordinary cement concrete, and the shrinkage rate of the high-toughness super sulfate cement is about 1/2 and 3/4 of that of super sulfate cement and ordinary cement concrete.
本发明涉及一种高韧性超硫酸盐水泥及其制备方法，属于建筑材料技术领域。本发明主要是克服现有技术中的不足之处，提出一种高强、高韧性、高耐久的高韧性超硫酸盐水泥及其制备方法，包括以下重量百分比的组分：矿渣65～90％、石膏10～25％、激发剂1～15％、掺合料1～10％、纤维0～3％、调凝型减水剂0～1％。本发明制备的高韧性超硫酸盐水泥的抗硫酸盐侵蚀能力约是超硫酸盐水泥、普通水泥混凝土的1.2倍、1.5倍，抗折强度约是超硫酸盐水泥、普通水泥混凝土的3倍、3.5倍，抗弯挠度约是超硫酸盐水泥、普通水泥混凝土的40倍、50倍，收缩率约是超硫酸盐水泥、普通水泥混凝土的1/2、3/4。
