Karakteristik Mortar Self-Healing Menggunakan Kapsul Sodium Silicate Dalam Larutan Asam Sulfat

---

ABSTRACT

The appearance of cracks in structural elements during the service life of construction led to the emergence of self-healing methods with encapsulation that can activate the self-healing performance of a structural element, especially mortar. This study aims to assess the characteristics of self healing mortar with the use of Sodium Silicate capsules against cracks that occur in sulfuric acid solution. Tests include mortar flow value, mortar setting time, compressive strength, porosity, sorptivity, mass change and visual observation of mortar cracks. This study used capsules containing sodium silicate gel as a self healing material at 0.25%, 0.50%, and 0.75% by weight of cement and normal mortar with 0% SS variation as control. Treatment of the specimens was carried out for 28 days in water, after which day 0 and pre-crack testing was carried out with a mortar compressive strength device until cracks with a width of 0.1-0.3 mm appeared. Treatment of the specimens continued for 0, 7, 28, and 91 days in sulfuric acid solution and then mortar tests were conducted. The results showed that the flow value, setting time, and compressive strength increased as the percentage of sodium silicate capsules increased with the highest compressive strength value at the 91st day SS 0.75% variation of 34.93 MPa. The porosity and sorptivity values increased on day 7 with the lowest value in the 0.75% SS variation on day 91. The self-healing efficiency values for 0% SS, 0.25% SS, 0.5% SS, and 0.75% SS variations were 76.96%, 100%, 89.06%, and 92.46% after 91 days of immersion in sulfuric acid solution. The conclusion is that mortar using sodium silicate capsules has better self healing characteristics than mortar without sodium silicate capsules.
