Strength of Concrete Containing Synthetic Wire Waste as Fiber Materials

Abstract

The demand of concrete in construction field is growing as linear with the growing of Malaysia economy. This tendency is expected to continue in the year ahead because of improvement in technology. This study tends to determine the performance of concrete containing synthetic wire waste as fiber materials. In addition, the use of wire waste as fiber materials can reduce the amount of waste dumped into landfills. The increasing amount of wire waste which is uncontrollable may lead to environment issue. Until today there is no researchers have done the studies on performance of concrete containing synthetic wire waste as fiber materials. Therefore, an action is made to overcome the environmental problems by using wire waste as fiber materials in concrete mixture. The amount of wire waste added into concrete mixture are limited to 0%, 0.5%, 1.0%, and 1.5% respectively. Other than that, water cement ratio that used is 0.55. The test that involve in this study is workability, density, compressive strength and tensile strength tests. The compressive strength test carried at the ages of 7 and 28 days and for tensile strength test were carried at ages of 28 days. The result was compared with control mix and the optimum percentage value of using wire waste as fiber materials in concrete was 0.5% for both compressive and tensile strength test. Concrete contains 0.5% of wire waste. These mix shows significant increases about 24.4% and 42.7% increases for compressive and tensile strength respectively, compared to the normal concrete.
