Abstract

Concrete is one of the construction structures used in construction, which is made of coarse aggregate like crushed stone, fine aggregate like sand, portland cement, water, and addictive substance like superplasticizers if needed which are mixed. In this study, the designed for concrete is the fine aggregate is a mixture from rock ash and bottom ash, the rest of materials are the same. With the current infrastructure development, the need for sand will be increasingly and this sand material will be increasingly depleted. The percentage in this study use rock ash and bottom ash is 75% rock ash and bottom ash is 25% of the variation in the volume ratio between waste materials and fine aggregate required. This study will use the following variations: Normal concrete (0% AB and 0 and 0% BA; 95% AB: 5% BA; 90% AB: 10% BA; 85% AB: 15% BA; 80% AB: 20% BA; 75% AB: 25% BA. From the results of the tests that have been conducted, the normal concrete compressive strength values are obtained at the age 28 days is 317.19 kg/cm². The compressive strength of concrete using a mixture of rock ash (95%) and bottom ash (5%) at ages 28 days is 361.90 kg/cm². For the compressive strength of concrete using a mixture of rock ash (75%) and bottom ash (25%) at ages 28 days, namely 303.85 kg/cm². So, the strength of concrete can decrease if the concrete mix is added with the percentage of bottom ash.
