Abstract

Based on the theory of damping energy dissipation, a damping concrete is made by choosing suitable rubber, additives, filling material and reasonable mixture ratio. The comparative experiments are made between normal concrete and rubber concrete, including damping performance and failure character. The specimens consist of four reinforced concrete beam by using variation of the concrete mixes. Natural sand in the concrete mixes was partially replaced by using recycled rubber powder of 5%, 10%, 15%, and 20% respectively. The specimens were vibrated using hammer impact and damping was recorded by using accelerometer sensor. The results of analysis show that the dumping of the rubber concrete structure was improved observably compared with that of the normal concrete structure.

Keywords: rubber concrete, accelerometer, damping.
