in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
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 ...
The urban heat island (UHI) effect poses significant challenges to environmental quality and public health. Over the decades, research efforts have been made develop various UHI mitigation strategies, including pavement materials, such as, water-retentive pavement, reflective pervious concrete. This paper focuses on improvement of hygric water retention properties concrete mitigate phenomena. h...
