Experimental Investigation on Impact Ductility of Polymer-Modified Concrete Subjected to Falling Weight Loading

Abstract:

The impact ductility of plain concrete and polymer-modified concrete with different p-c (polymer-cement) ratio were measured by bend-impact method. The impact-resistance of plain concrete and polymer-modified concrete were contrasted. The modified mechanism of polymer-modified concrete was analyzed. The results indicate that the impact ductility of concrete are increased with contents of polymer firstly and then reduced and the best p-c ratio is 15%. The test results also indicate that the concrete performance are modified by polymer, which prevent crack developing in microcosmic and improve impact ductility in macroscopic.
