Experimental Investigation on the Performance of Plastic Aggregate Concrete
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
This study is intended to explore the suitability of recycled high density polyethylene (HDPE) as coarse aggregate in concrete. Effect of replacement of coarse aggregate with various percentages (0% to 40%) of plastic aggregate on behaviour of concrete was experimentally investigated and the optimum percentage replacement of coarse aggregate was found out. The results showed that the addition of HDPE aggregate to the concrete mixture led to increase in the compressive strength of the concrete till a replacement of 30% of natural coarse aggregate. Also with the addition of plastic aggregate, the workability and tensile force of the resultant concrete increased. The bonding property of both the concrete mix was also studied with the help of pullout apparatus. The present investigation also focussed on the effect of H2SO4, HCl and Na2SO4 on concrete containing normal aggregate and plastic aggregate respectively. The rate of attack on mix containing plastic aggregate was comparatively less than that of control mix. The obtained results supported the use of HDPE aggregate for partial replacement of natural aggregate.
