The Performance of Cigarette Butts In Concrete Mixture
Cigarette butts (CBs) has been a threat to the environment since it is being introduced. To solve the issue of pollution made by these wastes, researches have made the attempts of incorporating cigarette butts into building materials such as asphalt concrete and fired clay bricks. This paper presents the performance of CB incorporate into 1:2:4 concrete mixing ratio by 2.5%, 5% and 10% of CBs. These samples were tested for basic concrete tests such compressive strength, rebound hammer, Ultrasonic Pulse Velocity (UPV) test and mass for each sample were taken. Overall, the incorporation of 5% of CBs in concrete is better than other ratio. The 5% of CBs is 35% and 5% lower than the normal concrete for both compressive and UPV test. Although the rebound hammer test is higher by 1.8% for 2.5% of CBs when compared to normal concrete. As predicted as the percentage of CBs increase, the concrete become lighter up to 11%. CBs reduced the overall strength of concrete thus making it not suitable for high and major construction. However, CB concrete can be applied for low cost construction and need further improvement on its strength in order to apply on major construction.
