Tanawa, Yanssen (2021) Analisis Penetrasi Klorida ke dalam Beton dengan Metode Error Function. Sarjana thesis, Universitas Brawijaya.
Abstract
Korosi merupakan permasalahan dari beton bertulang karena itu diperlukan uji analis penetrasi klorida untuk mengetahui laju difusinya. Model laju difusi klorida satu dimensi adalah berupa persamaan differensial parsial yang salah satu solusinya adalah menggunakan metode Error Function . Data yang diperlukan adalah koefisien difusi dan kadar klorida permukaan yang dapat diperoleh dari uji eksperimental kemudian dengan menyesuaikan waktu dan kedalaman sesuai eksperimen dapat diperoleh konsentrasi klorida di setiap interval kedalaman tertentu. Hasil analisis menunjukkan bahwa keakuratan dari metode error function untuk memodelkan penetrasi klorida dalam beton sangat ditentukan oleh nilai dari kadar klorida permukaan dan koefisien difusi yang digunakan sehingga harus teliti dalam perhitungan . Lebih lanjut juga dapat disimpulkan bahwa kadar klorida akan berkurang seiring dengan bertambahnya kedalaman dari permukaan juga semakin besar kadar klorida permukaan maka semakin dalam pula penetrasinya ke dalam beton.
English Abstract
Corrosion is a problem in steel reinforced concrete because of that its demanded a analysis test of chloride penetration to know the diffusion rate , one of the model is by Error Function method .Chloride is one of factor contributing to corrosion and not only endangered the structure that have direct contact with sea water but can also spread by the air. The data needed is diffusion coeficient and surface chloride concentration then by adjusting the suitable depth and time based on experiment will produce the chloride concentration in every certain depth interval . data is gathered from eksperimental test from the previous thesis or journal and then analyzed to see the fitness. The Results from analysis show that the accuracy of Error Function method in modelling the chloride penetration is really determined by the value of diffusion coeficient and surface chloride concentration used . so it must be careful in calculation. Moreover the results show many variation and really depends on the condition and situation of experiment so to get a good results will need a further investigation in many locations but in general, the chloride concentration will decrease with the the add of the depth from surface.
