| 1 | 混凝土基本组分吸收二氧化碳的能力(英文)显示文摘研究了利用混凝土产品吸收二氧化碳的可行性。混凝土的3个基本组分:水泥、细沙和骨料,都可被用来作为二氧化碳吸附物以实现储留最大化,另外,可利用高钙钢渣等工业废料生产混凝土骨料。研究发现波特兰水泥2h碳化后吸收14%二氧化碳,碳化后的材料的强度与7d传统养护的强度相当。钢包钢渣细粉能吸收4%~12%二氧化碳,能用来替代河沙。吹氧高炉钢渣对二氧化碳吸收的能力超过12%。由此制成的粗骨料其强度可与石灰岩相比。如果混凝土砌块由这3组分组成,一块20cm×20cm×20cm的标准砌块能吸收1.39kg二氧化碳。二氧化碳在混凝土中的储留是一项经济可行、直接减排的有效技术。 | 邵一心 MONKMAN Sean TRAN Stanley | 2010 | 硅酸盐学报2010，38，9： | 6 |
| 2 | NRG COSIA Carbon XPRIZE: carbon-dioxide mineralization in recycled concrete wash water显示文摘Wash water is generated as a waste stream from ready-mixed-concrete production.Reuse of the water as mixture water is limited,in practice,by the negative material performance impacts associated with the water chemistry and properties;the effects are intensified with increasing content of suspended solids and age.However,this waste material can be used as a beneficial additive to concrete by profiting from the cementitious properties of the suspended solids,if variability can be reduced.A method of stabilizing this material is through CO_(2) treatment.The added CO_(2) is mineralized through a reaction with the calcium from the cement particles.This provides a calcium-carbonate coating that prevents further cement hydration,making the material predictable.This has been shown to alleviate concerns with set acceleration and inconsistencies in compressive strength.A method of CO_(2) treatment was tested as part of the NRG COSIA Carbon XPRIZE at a site in Calgary,Alberta.The slurry for the treatment was provided by a local concrete plant and had a specific gravity of 1.15.The simulated wash water was treated in 1000-L quantities with each treatment mineralizing an average of 40 kg of CO_(2).The system ran for 1600 hours of operation over 127 treatment cycles and converted 14.5 tonnes of CO_(2) at an average mineralization efficiency of 80%.The treated slurry was used as an additive in>300 batches of concrete where the concrete met the necessary requirements for fresh properties and setting time,while achieving a strength benefit.Replacement of 5%and 10%of batch water with treated slurry(9.4 and 18.8 kg slurry/m^(3) concrete)showed a strength benefit of 3%and 6%compared to a reference.The technology was selected as the winner of the NRG COSIA Carbon XPRIZE(Track B:Natural Gas)in April 2021. | Sean Monkman Travis Janke Alex Hanmore | 2021 | Clean Energy2021，5，4： | 1 |
