one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

Underground water resources considered as a major source of fresh water. Increasing need to water in Iran, causing to immensely utilization and ground water balance disorder, so that state of ground water in many of area is negative.The purpose of this study is to investigate the trend of changes in some of the characteristics of groundwater during the period 1374 to 1387 is Segzi plain. For...

The Khuzestan plain is located in south western of Iran and is covered about 3.9 percent of the country area. Khuzestan plain is mostly covered by the Quaternary deposits. The thickness of these deposits exceeds 300m in some areas .Sedimentology and geochemistry of sand dunes producing centers are not only important for determining sedimentary and geochemical features of the particles possible ...

Background and Objective: Determination of quality parameters of drinkable water is important, especially in developing countries, to increase the productivity and better management and planning of water resources. The aim of current study was to apply CART decision tree data mining technique to determine the most effective factors on drinkable water quality in Kazeroon plain, located west of F...

Selecting an optimal interpolation method to estimate characteristics of an area of sampling points is not an important role in data management. One of the important indicators of quality of underground water is the electrical conductivity. Purpose of this study to select a suitability interpolation method from to evaluate and analyze the groundwater salinity SARKHON plain. To this appreciate w...

Introduction & Objective: Iran is located in the dry and semi dry regions, thus almost 90% of the required fresh water is exploited from groundwater resources. Due to the increasing pol-lution of water resources, the purpose of this study was evaluation of Pb, Cd, Cu and Mg concentrations in groundwater resources of Razan Plain and preparing the zoning map using GIS. Materials & Methods: Ground...
