Influence of Plastic Bottles Fibre on Self Compacting Concrete

It is well known to all of us that water plastic bottles waste has become a major problem to the environment. At the same time, incorporating the fibres in concrete like polypropylene is advantageous as they improve its properties. Nowadays self compacting concrete (SCC) has become very common in casting concrete due to its high flow properties and attained the required strength. The aim of this research is to study the effect of addition of shredded waste water plastic bottles to the constituents of SCC and comparing the results with those resulted from employing polypropylene fibre available in the market to the mix. In the study, SCC was produced at constant water content of 0.4 with the addition of constant super-plasticizer of 2% of cement weight, four fibre contents of 0.05, 0.075, 0.1 and 0.125 of the cement weight were employed to the mix, and then fresh and hardened properties of concrete were measured. From the results obtained, it was clearly observed that fresh and hardened properties of SCC can be obtained by using fibres produced from recycled water plastic bottles, and that off course will help in minimizing the pollution of environment.
