地面循环流化床粉煤灰优化低碳轻质泡沫混凝土
组成材料:P·I 42.5硅酸盐水泥、CFBFA、发泡剂。水泥表观密度为3110 kg/m3。CFBFA产自中国山东省,表观密度为2100 kg/m3,着火损失为15.89%。CFBFA与水泥的化学成分如表1所示。CFBFA的主要成分是SiO2和Al2O3。同时还含有少量的Fe2O3、SO3、CaO和TiO2。图1为CFBFA的x射线衍射(XRD)图。主设置时间10为不同GCFBFA取代比水泥的实测凝结时间。可以看出,GCFBFA使水泥初凝时间和终凝时间延长。S30和S70的初凝时间分别为156分钟和185分钟,比S0分别延长了25%和48%。S30和S70的最终凝固时间分别延长了55%和103%。以上结果表明,GCFBFA对最终凝固时间的影响更大。结论在本研究中,GCFBFA作为SCM制备低碳LFC。结果表明:(1)GCFBFA与水泥发生的主要反应是火山灰反应,GCFBFA中的硫酸盐促进了AFt的生成,掺入30% GCFBFA的粘结剂强度最大,反应程度最高,产生的水化产物最多。(2)GCFBFA延缓水泥水化,延长凝结时间,降低总水化热,未引文献esong - woo等,2021。数据可得性应要求提供数据。竞争利益声明作者声明,他们没有已知的竞争经济利益或个人关系,可能会影响本文所报道的工作。国家重点基础研究项目(No. 2022YFC3005604);国家自然科学基金(No. 52378250);山东省泰山学者基金项目(B21012);tsqn201909032)和济南市科技局“揭牌指挥”项目(202323007)。

期刊介绍: The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
