SUMMARY
MHD. RAJA ALFADH, NIM. 2210248026, Self-Healing Mortar Contained Nanosilica under Wet-Dry Conditions in NaCl Solution, Supervised and proctoring by Monita Olivia and Gunawan Wibisono
In the marine environment, mortar as a construction material is susceptible to exposure to aggressive substances that can reduce its resistance and durability. This study aims to assess the characteristics of mortar with nanosilica addition in static and wet-dry treatments in sodium chloride (NaCl) solution. In this study, nanosilica with percentages of 0.75%, 1.5%, and 2.25% was added to Portland Composite Cement (PCC) mortar. PCC mortar without nanosilica addition was used as control mortar.
The mortar samples were soaked in water for 28 days, then subjected to loading until cracks 0.1 to 0.3 mm wide were formed. The cracked mortar was then immersed in 3.5% NaCl solution under static and wet-dry treatment conditions and tested at 7, 28, and 91 days of age. The tests include compressive strength, sorptivity, chloride penetration, visual self-healing and microstructure analysis using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR).
The results showed that increasing the percentage of nanosilica in mortar can increase compressive strength, decrease sorptivity, reduce chloride penetration, and improve the microstructure of cracked mortar. The self-healing efficiency of statically soaked mortar was higher than that of mortar subjected to wet-dry cycles. Thus, nanosilica can be used as an effective additive to improve the durability of mortar in an environment containing NaCl solution.
Keywords: mortar, NaCl, nanosilica, self-healing, wet-dry.
