Performance of Fresh And Hardened Concrete Essay

Performance of Fresh And Hardened Concrete - Essay Example The researcher states that today there is an increasing trend for using recycled materials to create new concrete in order to increase sustainability and decrease costs among other factors. The effects of the recycled aggregates on the created concrete can be minimal to significant depending on a host of factors. The properties of concrete are affected both in the fresh state and in the hardened state and so there is great need to understand how the use of recycled aggregates affects concrete. The various kinds of recycled aggregates in use include recycled concrete aggregate (RCA), recycled wash glass sand, recycled rubber tyres and others. This text will attempt to analyse the effects of recycled aggregates on the fresh properties of concrete and on the properties of hardened concrete. Based on the investigations and results presented above it is obvious that the addition of recycled aggregates affects the properties of concrete significantly. The inclusion of recycled aggregates t o concrete helps to increase the sustainability and reduce the cost of the build but compromises on the strength achieved. Therefore concrete created with these methods can be utilised for less demanding tasks that require lower loading. In some cases however, the addition of aggregates has helped improve some of concrete’s abilities especially fresh concrete’s workability and other properties. More investigation into creating concrete with the inclusion of aggregates can help to boost sustainability and decrease costs further.
