Synthesis of multiwall carbon nanotube with fly ash in the production of desired green concrete

Abstract

Green concrete was introduced in concrete production in order to reduce the usage of natural resources. In this research, fly ash and MWCNTs were used in the production of green concrete since industrial waste material such as fly ash becomes a major concern during waste disposal. MWCNTs was used in this experiment to strengthen this green concrete. In this paper, effect of heat during curing process was studied and it was found that the compressive strength was increase when introducing the heat during curing process of this green concrete. The 3 days of water curing at room temperature and 3 days of heat curing at 100°C produces compressive strength at 27.2 MPa which is higher than normal curing process at 28 days, which is 14.63 MPa. Therefore, this research shows that green concrete can be produced using fly ash and MWCNTs and produce high compressive strength when heat was presence during curing process. © Published under licence by IOP Publishing Ltd.
