Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...
A large number of reinforced concrete structures subjected to chloride ions. Two basicapproaches for preventing corrosion of reinforcing steel embedded in concrete are: Increasing theconsolidation of concrete and using different coating on rebars. In present research steel rebarsare coated in different ways: a) 40 µm of zinc electroplated on steel rebar b) Zinc powder withepoxy paste (zinc rich...
Attack and disintegration of concrete structures under the influence of aggressive fluids, wet gases, etc. are understood as corrosion of concrete. The corrosion of concrete is a chemical, colloidchemical process, yet often a physico-chemical one, while that of reinforced concrete supported oil platforms are subjected to marine environment in the Persian Gulf and therefore corroded. In the pres...
مقدمه و هدف: تشخیص متداول دو بیماری تیلریوز و بابزیوز در ایران بر اساس رنگ آمیزی گسترش ها ی خونی دامهای مشکوک با رنگ گیمسا می باشد. این نوع رنگ آمیزی بعنوان یک روش ساده ، ارزان و قابل استفاده در تمام آزمایشگاهها مطرح می باشد. اما از آنجایی که این رنگ آمیزی غیر اختصاصی است لذا تشخیص و تفکیک جنس و گونه اجرام انگلی بسیار مشکل و نیاز مند تجربه تخصصی بالا می باشد. برای مثال در بعضی موارد بعلت تشابه ...
introduction: nowadays different countries benefit from health system based on health cards and projects related to smart cards. lack of facilities which cover this technology is obvious in our society. this paper aims to design minimum data sets of health smart card system for iran. methods: this research was an applied descriptive study. at first, we reviewed the same projects and guidelines ...
