Preparation method of hybrid fiber and nano material reinforced geopolymer concrete
The invention discloses a preparation method of hybrid fiber and nano material reinforced geopolymer concrete, and belongs to the technical field of building materials. The preparation method comprises the following steps: uniformly mixing the nano silicon dioxide, the reinforced fibers, the water reducing agent and the alkali activator; and adding metakaolin, fly ash, fine aggregate and coarse aggregate, and uniformly stirring to obtain the hybrid fiber and nano material reinforced geopolymer concrete. Aiming at the defects that geopolymer concrete is easy to crack, low in toughness and the like, the invention develops hybrid fiber and nano material reinforced geopolymer concrete. The reinforced fiber and the nano material are doped into the geopolymer concrete, so that the mechanical property and the impact resistance of the prepared hybrid fiber and nano material reinforced geopolymer concrete are effectively improved.
本发明公开了一种混杂纤维和纳米材料增强地聚合物混凝土的制备方法，属于建筑材料技术领域。所述制备方法的步骤包括：将纳米二氧化硅、增强纤维、减水剂与碱激发剂混合均匀；再加入偏高岭土、粉煤灰、细骨料和粗骨料，搅拌均匀，即制得混杂纤维和纳米材料增强地聚合物混凝土。本发明针对地聚合物混凝土易开裂、韧性低等缺陷，开发了一种混杂纤维和纳米材料增强地聚合物混凝土。通过在地聚合物混凝土中掺入增强纤维和纳米材料，有效地提高了所制得混杂纤维和纳米材料增强地聚合物混凝土的力学性能、抗冲击性。
