Karakteristik Mortar Self-Healing Menggunakan Abu Cangkang Kerang Dalam Larutan Nacl Dengan Metode Perawatan Statis

---

ABSTRACT

Seawater has aggressive properties that can cause cracks and reduce the durability of mortar, self-healing technology can repair these cracks independently and thus reduce repair costs. Calcined shell waste has calcium oxide (CaO) compounds that have self-healing ability by filling the cracks of mortar. The purpose of this study was to examinethe effect of variations in clam shell ash on theabilityof self-healing mortar in NaCl solution. This research used clam shell ash as self-healing agent with variations of normal as control, 2.5%, 5%, and 7.5% by weight of cement. Tests were conducted including flow value, setting time, compressive strength, sorptivity, porosity, chloride penetration, and visual mortar. The test specimens were cured for 28 days, then in addition to the 0-day soaking age test specimens, the other test specimens went through a pre-crack process with a compressive strength device. After that, the specimens were immersed in 3.5% NaCl solution at the age of 0, 7, 28, and 91 days with static treatment method. The results showed that mortar with the addition of clam shell ash had the lowest flow value, porosity, and sorptivity as well as the longest setting time compared to normal mortar. The highest compressive strength value is produced by the 5% ACK variation with a value of 34,20 MPa and the lowest compressive strength is found in normal mortar with a value of 30.13 MPa at the age of 91 days. Mortar variations of 5% ACK and 7,5% ACK have good self-healing ability and can close the crack gap at the age of 91 days with a percentage of 100%. Thenormal mortar variation without clam shell ash and the 2.5% clam shell ash variation experienced lower crack closure compared to the 5% and 7.5% variations. Therefore, the use of clam shell ash as an additive to mortar can improve its self-healing ability in NaCl solutions.

Keywords: Self-healing mortar, pre-crack, clam shell ash, NaCl solution, static.
