Single-component regenerated geopolymer cement concrete
The invention belongs to the technical field of concrete, and particularly relates to single-component regenerated geopolymer cement concrete. The concrete comprises following raw materials: recycledgeopolymer cement, water, natural fine aggregate, a recycled sand/powder mixture, coarse aggregate and an additive. The single-component geopolymer regenerated cement is prepared by mixing a volcanicash mineral admixture (such as fly ash and slag), the regenerated sand/powder mixture and a solid alkali activator and then carrying out ball milling. The geopolymer regenerated cement is produced byactivating the activity of the regenerated sand/powder mixture and the volcanic ash mineral admixture (such as fly ash, slag and meta-kaolin) by utilizing the mechanochemical action in the ball milling process. The regenerated sand/powder mixture is adopted to replace part of fine aggregate to produce the regenerated geopolymer cement concrete, so that the recycling value and the recycling rate ofthe regenerated sand/powder mixture are effectively improved.
本发明属于混凝土技术领域，具体涉及一种单组分再生地聚合物水泥混凝土。其原料包括再生地聚合物水泥、水、天然细骨料、再生砂/粉混合物、粗骨料、外加剂；本发明采用火山灰性矿物掺合料（如粉煤灰、矿渣）、再生砂/粉混合物与固体碱激发剂混合后进行球磨制成单组分地聚物再生水泥。利用球磨过程中的机械化学作用激活再生砂/粉混合物、火山灰性矿物掺合料（如粉煤灰、矿渣和偏高岭土）的活性生产地聚物再生水泥，并采用再生砂/粉混合物取代部分细骨料，生产再生地聚物水泥混凝土，可有效提高了再生砂/粉混合物的资源化价值和资源化率。
