ABSTRACT

Cracks in civil engineering structure components are one of the problems that occur during the service life of a civil building. The cracks in the building can be a pathway for the entry of destructive substances for the substances inside. In this research, an innovation was carried out by utilizing the ability of self-healing mortar with the help of several replacement materials that will be observed how they affect the ability of self-healing mortar, namely used tire waste processed into rubber powder, fly ash from coal combustion waste, and also the use of silica fume. Four variations of concrete mix in this study, namely normal mortar as control mortar, 5% rubber powder mortar, 5% rubber powder mortar + 5% fly ash, 5% rubber powder mortar + 5% fly ash + 10% silica fume. The control mortar is 100% PCC with a plan compressive strength of 20 MPa. The 28-day old mortar will be given a pre-crack with a control width of 0.1 - 0.3 mm using a thin steel plate, then the test specimens will be treated for 0, 7, 28 and 91 days using the wet-dry immersion method for 24 hours in plain water and 24 hours in outside air and then tests will be carried out on the mortar. The test results showed that the flow value, setting time decreased, and the compressive strength of mortar with SK-AT-SF variation had the highest compressive strength at the age of 91 days after pre-crack of 26.07 MPa. The porosity and sorptivity test results showed the lowest value in the SK-AT-SF variation at the age of 91 days. Visual results produced self-healing efficiency values in the control, SK, SK-AT, SK-AT-SF variations of 63.31%, 92.74%, 93.14%, and 100% after 91 days of wet-dry soaking. The most optimal is 100%at the ageof 91days, Theconclusion is thatmortar with SK-AT-SF variations has better self-healing ability than the control mortar.

Keywords: self-healing, rubber powder, fly ash, silica fume, crack.
