Fiber-reinforced geopolymer based on recycled concrete aggregate and preparation method thereof
The invention discloses a fiber-reinforced geopolymer based on recycled concrete aggregate and a preparation method thereof. The fiber-reinforced geopolymer comprises recycled concrete aggregate, meta-kaolin, quartz sand and polyethylene fibers. The provided fiber-reinforced geopolymer based on recycled concrete aggregate has high compressive strength and compact texture, is widely applied to thefield of various building materials, has a strong environmental protection performance, effectively improves the overall compressive strength of the geopolymer, and ensures the bonding stress betweenthe geopolymer and fibers; the coarse aggregate powder is relatively weak in chemical activity, but can slowly react with an alkali-activated solution in the later period of a chemical reaction, so that the later strength of the mortar is guaranteed, the later strength of the geopolymer is further enhanced, and the geopolymer has high compressive strength, ductility and 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纤维增强地聚合物及其制备方法，所述纤维增强地聚合物数包括：再生混凝土骨料、偏高岭土、石英砂，还包括聚乙烯纤维。本发明提供的基于再生混凝土骨料的纤维增强地聚合物具有较高的抗压强度，质地较为致密，广泛适用于各种建材领域，具有较强的环保性能，有效提高了地聚合物的整体抗压强度，并保证了与纤维之间的粘结应力；粗骨料粉末的化学活性相对较弱，但可以在化学反应后期与碱激发溶液缓慢反应，保证了砂浆的后期强度，进一步增强了地聚合物的后期强度，同时具有高抗压强度和延性，且具有较高的环保性能，适用于建材领域。
