Abstract

Concrete is the most widely used building material in the world. The cracks present in the concrete are progressive, so the potential cracks must be prevented early. One way to reduce cracks in concrete is using bacterial added materials that are able to make concrete recover independently or also called self-healing concrete. The purpose of this study was to see the effect of the addition of vegetable waste extract and concrete additives on the compressive strength of self-healing concrete). The method used in this study is an experimental method, which is to see the effect of treatment on self-healing concrete by adding vegetable waste extract and betonmix. This study used a cube-shaped test object with a size of 15 cm x 15 cm x 15 cm as many as 27 test objects, with variants of vegetable waste extract of 0%, 3%, 5%, 7% and 9% as a substitute for part of cement and the addition of betonmix by 1% of the weight of cement. For each variant there are 3 samples of test objects, the planned concrete is 28 days old with test objects in the form of compressive strength tests and crack recovery tests. Based on the results of the research analysis, the compressive strength of concrete on self-healing concrete with the addition of betonmix concrete aged 28 days with vegetable waste extract variants of 0%, 3%, 5%, 7% and 9% as a substitute for cement respectively is 47.36 MPa; 37.12 MPa; 32.65 MPa; 40.31 MPa; and 36.58 MPa. The compressive strength of concrete after planting with vegetable waste extract variants of 3%, 5%, 7% and 9% is 38.75 MPa; 41.18 MPa; 41.63 MPa; and 33.96 MPa. The compressive strength of concrete after hatching experienced the highest increase in the 5% variant with an increase of 26.13% compared to 28-day-old concrete in the same variant. The results of visual observations showed that the concrete did not undergo significant changes. Cracks that close are cracks on a small scale or the size of a strand of hair.
