Abstract

Ground repair material is an essential part of the grounding system as a lightning rod to reduce the risk of lightning activity. Grounding repair materials consist of conductive and superconductive materials, commonly known as Ground Enhancement Materials (GEM). GEM has a low resistivity, very effectively supporting lightning shock energy to earth. Vitric tuff, a pyroclastic rock, is composed of an aluminosilicate (phyllosilicate) mineral group developed as a grounding improvement material. The primary purpose of this study was to determine the decrease in resistivity of vitric tuff in its development as a GEM. The research method consisted of field observations and laboratory experiments (treatment with chemical-physical activation and formulation with additives). The results showed that moisture content, SiO2/Al2O3 ratio (quartz and feldspar mineral/albite), clay mineral, crystal quality (impurities), carbon, and salt were influenced by vitric tuff resistivity. With the vitric tuff formulation and additives, the resistivity reduction is above 99%. Based on experiments, the best formulation of GEM made from tuff is 65% activated vitric tuff, 27% activated charcoal, 6% NaCl, and 2% Cement Material Cellulose. The formula produces a resistivity value of 0.0124 Ω-m, which is stable with time and meets GEM requirements (ρ ≤ 0.20 Ω-m).

玻璃质凝灰岩地阻性能的时间防御性及其在地面增强材料开发中的应用

接地修复材料作为避雷针是接地系统的重要组成部分，可以降低雷电活动的风险。接地修复材料分为导电材料和超导材料，俗称接地增强材料(GEM)。GEM具有低电阻率，非常有效地支持雷击能量到地球。玻璃凝灰岩是一种火山碎屑岩，由铝硅酸盐(层状硅酸盐)矿物群组成，是一种接地改善材料。本研究的主要目的是确定玻璃凝灰岩在其作为GEM发育过程中电阻率的降低。研究方法包括实地观察和室内实验(化学物理活化处理和添加剂配方)。结果表明:水分含量、SiO2/Al2O3比(石英和长石矿物/钠长石矿物)、粘土矿物、晶体质量(杂质)、碳和盐均受玻璃凝灰岩电阻率的影响;采用玻璃质凝灰岩配方和添加剂，电阻率降低99%以上。通过实验得出凝灰岩制备GEM的最佳配方为:活化凝灰岩65%、活性炭27%、NaCl 6%、水泥材料纤维素2%。公式得到的电阻率值为0.0124 Ω-m，随时间稳定，满足GEM要求(ρ≤0.20 Ω-m)。印尼地质与矿业学报，Vol.31, No . 2, page 63-76 doi: 10.14203/risetgeotam2021.v31.1149
