Anti-efflorescence geopolymer based on recycled concrete aggregate, and preparation method thereof
The invention discloses an anti-efflorescence geopolymer based on recycled concrete aggregate, and a preparation method of the anti-efflorescence geopolymer. The anti-efflorescence geopolymer comprises the following components: recycled concrete aggregate, metakaolin, quartz sand and an alkali-activated solution. According to the invention, the efflorescence-resistant geopolymer based on the recycled concrete aggregate has relatively high compressive strength and relatively compact texture, is widely applied to the field of building materials, and has relatively strong environmental protectionperformance; metakaolin has strong chemical activity, can consume metal ions in a large scale in the early stage of chemical reaction, avoids the early saltpetering phenomenon, and ensures the earlystrength; quartz sand has high fineness, and can slowly react with the alkaline ions in the matrix so as to further avoid the later saltpetering phenomenon of the material; and the efflorescence-resistant geopolymer has characteristics of high compressive strength, high saltpetering resistance and high environmental protection performance, and is suitable for the field of building materials.
本发明公开了一种基于再生混凝土骨料的抗泛碱地聚合物及其制备方法，抗泛碱地聚合物包括以下组分：再生混凝土骨料、偏高岭土、石英砂与碱激发溶液。本发明提供的基于再生混凝土骨料的抗泛碱地聚合物具有较高的抗压强度，质地较为致密，广泛适用于建材领域，具有较强的环保性能；偏高岭土具有较强的化学活性，可以在化学反应前期大规模的消耗金属离子，避免出现早期泛碱现象，并保证了早期强度；石英砂具有较高的细度，可以与基体中的碱性离子缓慢反应，进一步避免了所述材料的后期泛碱现象，本发明的抗泛碱地聚合物同时具有高抗压强度和抗泛碱性能，且具有较高的环保性能，适用于建材领域。
