Green low-carbon cementing material and preparation method thereof
The invention provides a green low-carbon cementing material and a preparation method thereof, and belongs to the technical field of building materials. According to the method, the converter slag is pretreated to obtain the superfine converter slag, so that the activity and fluidity of the converter slag are improved; the sodium hydroxide, the liquid sodium silicate and the sodium chloride are used as alkali activators to be compounded to obtain the alkali activator, so that the early-stage and later-stage compressive strength of the concrete obtained by replacing cement with the green low-carbon cementing material is improved; the environment-friendly low-carbon cementing material can be further improved by adding the emulsified asphalt and the PE fiber into the raw materials, so that the use amount of the environment-friendly low-carbon cementing material capable of replacing cement is improved.
本发明提供了一种绿色低碳胶凝材料及其制备方法，属于建筑材料技术领域。本发明先将转炉渣进行预处理获得超细转炉渣，从而提高转炉渣的活性和流动性；通过将氢氧化钠、液体水玻璃和氯化钠作为碱激发剂进行复配作为碱激发剂，从而提高绿色低碳胶凝材料替代水泥获得的混凝土的早期和后期抗压强度；本发明通过在原料中加入乳化沥青和PE纤维可以进一步提高绿色低碳胶凝材料，从而实现提高绿色低碳胶凝材料可以替代水泥的用量。
