The invention discloses a high-performance geopolymer concrete and a preparation method thereof. The geopolymer concrete is prepared from, by mass, 1550 to 1600 parts of mineral powder, 155 to 165 parts of silica fume, 250 to 270 parts of fly ash, 500 to 1200 parts of fine aggregate, 200 to 800 parts of ceramic ball aggregate, 867 to 892 parts of an exciting agent, 78 to 234 parts of fiber, 20 to 24 parts of a water reducing agent and 0 to 109 parts of water. Ceramic balls and the steel fibers are co-doped into the geopolymer concrete, the fibers can effectively hinder the formation of microcracks in the concrete and significantly improve the tensile strength, bending resistance and impact resistance of the concrete, and the ceramic ball aggregate can inhibit the self-constriction phenomenon of the geopolymer concrete and promote the performance of good volume stability and durability, high hardness and small density of the concrete, and is compounded with other raw materials of the concrete to effectively improve the defects of self-constriction and high brittleness of the existing geopolymer concrete.
本发明公开了一种高性能地聚合物混凝土及其制备方法。所述地聚合物混凝土包括如下质量份数的原料：矿粉1550～1600份，硅灰155～165份，粉煤灰250～270份，细骨料500～1200份，陶瓷球骨料200～800份，激发剂867～892份，纤维78～234份，减水剂20～24份，水0～109份。本发明将陶瓷球与钢纤维共同掺入地聚合物混凝土中，利用纤维能够有效阻碍混凝土内部微裂缝的形成，显著改善混凝土的抗拉、抗弯及抗冲击性能以及陶瓷球骨料能够抑制地聚合物混凝土的自收缩现象，促进混凝土体积稳定性和耐久性好、硬度高、密度小的性能，与混凝土其他原料共同复配，有效改善现有地聚合物混凝土自收缩和脆性大的缺陷。
