در این مقاله روشی جدید برای سنجش مقاومت بتن در مقابل نفوذ یون‌های کلرید ارائه شده است که شامل اشباع‌سازی نمونه‌ها توسط محلول NaCl 5 مول، قبل از اندازه‌گیری رسانایی آنها می‌باشد. با اشباع کردن نمونه‌ها توسط محلول با رسانایی بالا، رسانایی‌های نمونه‌های مختلف بتنی متناسب با ساختار منافذ آنها می‌شود. برای بررسی عملکرد این روش، طرح‌های اختلاط مختلف بتن ساخته شد. مشاهده گردید که نتایج روش ارائه‌شده حساسیت کمتری نسبت به رسانایی مایع منفذی درمقایسه با روش‌های آزمایش نفوذ تسریع‌یافتۀ یون‌های کلرید (RCPT) و رسانایی حجمی (BC) دارد. همچنین ارتباط خوبی بین نتایج این روش با نتایج آزمایش انتشار حجمی (BD) به‌دست آمد.
