SIT (2023):罗祖亮、陈子航、郭述嫣、孔景润、刘子芃。他们的课题是研究废弃混凝土的完全利用评估及优化。将废混凝土回收破碎之后的粗细骨料及粉末按照已有研究在不影响混凝土强度的前提下以最大比例替换混凝土中的骨料及混凝土,并考虑到再生骨料的使用对混凝土CO2吸收水平的提升,对再生混凝土全生命周期环境和经济效益进行评估。


  SIT (2023):庄泽锐、刘帅、艾攀元、李艺、莫明宇。他们的课题是研究再生混凝土的性能随着循环次数的变化规律,并评估整个过程的环境和经济效益,以实现最大限度地利用建设和拆除产生的废弃资源,减少建设和维护带来的经济负担。

  SIT(2018): Liu yin, Liu bo, Chen Shijin, Shen Jiacheng and Lin ZijieDuring their project (Properties of mortar prepared with calcined coal gangue and limestone powder after exposed to elevated temperatures), they explored the new type of cement made from coal gangue, which aimed to reduce carbon emissions in cement preparation and utilize the waste of coal production. This project began in 2018 and ended in the second half of 2019. We have conducted a series of experiments and obtained relevant data.

  SIT(2017): Gan Binlin, Qiao Yu, Wu Haoze, Luan Liujie, Fang Wenqi. They are working closely with Ph.D and master students. During their project (Artificial Aggregate Made of Waste Concrete; High Temperature of CO2 Curing Concrete Block), they will explore the culture of research and discover a variety of experimental techniques. The idea is to give them the opportunity to gain some sort of research experience. 


Project summary: 
  As an important part of construction waste, waste concrete has received much attention for its handling and resource utilization. After years of exploration, the recycling level of waste concrete has been greatly improved, but the recycled fine powder produced during the crushing process of abandoned concrete has not been effectively utilized.
  Through interviews with relevant government departments, enterprises and social organizations in the waste concrete treatment and resource utilization of Changsha City, we will understand the sources, treatment methods and resource utilization status and related policies of waste concrete in Changsha City. The annual production of waste concrete in the year and the next three years, and the problems in the process of resource utilization of waste concrete are analyzed. In combination with the problem that the regenerated fine powder could not be effectively utilized, the research idea of ​​preparing artificial aggregate based on granulation and carbonization process to recover waste was proposed, and the artificial aggregate was prepared by rotary disc granulator, and in natural conditions and carbonization conditions respectively. Under the maintenance, study the effects of different mechanical parameters, curing methods, cement content on the bulk density, compressive strength and other properties of artificial aggregate.
