Experimental and Nonlinear Dynamic Analysis of Hybrid Powder Rubberized-Normal Concrete under Impact Load
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 11
Abstract
The effect of cement reduction on the behavior of hybrid concrete (double-layer beam with a rubberized top and a normal bottom) under the impact of three-point bending loading is investigated in this study. The experiment was conducted through the proportional addition of waste powder rubber. Concrete specimens were prepared by adding 5% and 20% rubber powder as filler and by decreasing cement by the same percentage. Two types of specimens (size 50×100×400 mm), namely, plain and hybrid concrete, were loaded onto a drop-weight impact machine by subjecting to 20 N weight from a height of 300 mm. Similar specimens were used for the static load test. Bending load-displacement behavior was analyzed for the plain and hybrid concrete beams under static and impact loads. A three-dimensional finite-element method simulation was also performed using LUSAS V.14 to study the impact of load-displacement behavior. The predictions were validated using the experimental results. The results reveal that the impact of bending load in the hybrid beam increases with the increased percentage of rubber powder, whereas the static peak of bending load decreases significantly.
