Abstract

The evolution of high performance geopolymer concrete (GPC) has become additionally significant for researchers and industry professionals due to the environmental issues related with the use of bulk cement in construction projects. By using fly ash (FA), bottom ash (BA), slag (GGBS), rice husk ash (RHA), and other industrial wastes as the principal binder instead of Portland cement, these mixes promote a greener approach to bulk concrete production. These high-performance blends are often associated with the incorporation of nanomaterials (NM) in the mix. Moreover, it has been demonstrated that NM incorporation offers GPC blends superior mechanical properties, and frequently does away with the requirement for thermal curing which further reduces the energy demand for production. This incorporation of NM also results in a denser inter-particle packing at a micro level, which increases the blend’s durability. The performances of GPC blends dosed with various NM, such as carbon nanotubes (CNT), nano-silica (NS), nano-alumina (NA), nano-titanium di oxide (NT), nano-clay (NC), and nano-graphene oxide (NG), are thoroughly summarized in this article in terms of mechanical, durability, and microstructural qualities. The final inferences and conclusions were drawn keeping in mind the viability of bulk consumption. Ultimately, TOPSIS analysis was carried out to determine the optimum type and dosage of NM in GPC and it was found that NS dosed at 2% yielded the most favorable outcomes. Present limitations and challenges related to the bulk utilization of GPC doped with NM are also discussed towards the end of this review, along with potential directions for further research.

土工聚合物混凝土的进展:纳米材料集成工程特性详述
由于在建筑项目中使用散装水泥所带来的环境问题,高性能土工聚合物混凝土(GPC)的发展对研究人员和行业专业人士来说变得更加重要。通过使用粉煤灰 (FA)、底灰 (BA)、矿渣 (GGBS)、稻壳灰 (RHA) 和其他工业废料代替硅酸盐水泥作为主要粘结剂,这些混合物促进了一种更环保的大体积混凝土生产方式。这些高性能混合物通常与混合物中掺入纳米材料(NM)有关。此外,事实证明,掺入 NM 可使 GPC 混合物具有更优越的机械性能,而且经常不需要热养护,从而进一步减少了生产过程中的能源需求。掺入 NM 还能使微观层面上的颗粒间堆积更加致密,从而提高混合物的耐久性。本文从机械、耐久性和微观结构质量等方面全面总结了掺入各种 NM(如碳纳米管 (CNT)、纳米二氧化硅 (NS)、纳米氧化铝 (NA)、纳米二氧化钛 (NT)、纳米粘土 (NC) 和纳米氧化石墨烯 (NG))的 GPC 混合物的性能。在得出最终推论和结论时,考虑到了批量消费的可行性。最后,进行了 TOPSIS 分析,以确定 GPC 中 NM 的最佳类型和用量,结果发现,用量为 2% 的 NS 能产生最有利的结果。本综述的最后还讨论了与掺入 NM 的 GPC 的批量利用有关的当前限制和挑战,以及进一步研究的潜在方向。
