Improvement of Recycled Aggregates Properties by Means of CO2 Uptake
نویسندگان
چکیده
Concrete from deconstruction can have a second life in the form of recycled concrete aggregates (RCAs). They unfortunately poor properties (high porosity and water absorption coefficient (WAC)) with respect to natural aggregates. Accelerated carbonation was implemented improve RCA increase their use by storing carbon dioxide (CO2) cement matrix thereby reduce environmental impact. This paper aims perform parametric study process for accelerated RCAs store largest possible amount CO2 properties. highlights fact that each these parameters affects storage, an optimum content maximum uptake depending on nature source RCAs. is related linear relationship. The results show reduces as much 67%. Finally, also decreases porosity, observed mercury intrusion porosimetry, filling capillary pores.

15 صفحه اولInvestigating properties of fresh and hardened self-compacting concrete made of recycled aggregates
Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...
متن کاملPerformance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
