Geopolymer regenerated mortar with fiber orientation structure and preparation method of geopolymer regenerated mortar
The invention belongs to the technical field of building materials, and particularly relates to geopolymer recycled mortar with a fiber orientation structure and a preparation method of the geopolymer recycled mortar. 100 to 300 parts of fly ash; 100 to 300 parts of mineral powder; 50 to 150 parts of an alkali activator; 4 to 10 parts of a retarder; 80 to 200 parts of water; and 0-80 parts of fiber. The mortar is prepared by the following method: weighing the raw materials meeting the particle size requirement according to the batch feeding amount, and mixing the recycled fine aggregate, the fly ash, the mineral powder, the alkali activator, the retarder, the fiber and the water; the mixture is put into a high-pressure injection molding instrument, and after the high-pressure injection molding instrument is filled, the mold is detached from the molding instrument; and putting the removed mold into a standard curing chamber for curing, then removing the mold, and putting the test block back to the standard curing chamber for continuous curing to obtain a product. The fibers are doped into the geopolymer regenerated mortar, the fibers in the mortar are promoted to be arranged and oriented in the flowing direction by using a high-pressure injection molding instrument, and the tensile strength of the mortar in the orientation direction and the bending resistance of the mortar in the vertical orientation direction are improved.
本发明属于建筑材料技术领域，具体涉及一种具有纤维取向结构的地聚物再生砂浆及其制备方法，砂浆由以下质量份组成：再生细骨料1200‑1400份；粉煤灰100‑300份；矿粉100‑300份；碱激发剂50‑150份；缓凝剂4‑10份；水80‑200份；纤维0‑80份。砂浆由以下方法制备：按批投料量称取所述符合粒径要求的原料将再生细骨料、粉煤灰、矿粉、碱激发剂、缓凝剂、纤维和水混合；将混合物放入高压注射成型仪，填满后，将模具从成型仪拆下；将拆下的模具放入标养室中进行养护后拆模，将试块放回标养室继续养护，得到产物。本发明在地聚物再生砂浆中掺入纤维，通过使用高压注射成型仪，促使砂浆内部的纤维沿流动方向排列取向，提升砂浆在沿取向方向的抗拉和垂直取向方向的抗弯性能。
