Effect Of Environment With Heavy Industrial Pollution On The Selection Of Concrete Mix For Building Structures
Authors : Ul-hamid Anwar . Saricimen Huseyin .
Abstract
This study proposes durable concrete mix design suitable for use in superstructures of an industrial plant of a cement company located in an area marked by heavy industrial pollution. Concentration of pollutants in the environment was recorded by undertaking ambient air quality monitoring along with an assessment of corrosivity of soil and ground water present at the site. Type of reinforcement, concreting procedures and protection methods were determined for reinforced concrete that was intended to be used in conjunction with steel structures. Experimental results indicated that soil and groundwater constituted no risk for the substructure. However, air was highly polluted and deemed to be severely corrosive due to the presence of chloride and sulfate salts, SO2 and CO2 in concentrations recorded several times higher than at a comparable industrial area. A concrete mix design suitable for observed conditions was recommended. Additionally, it was suggested that concrete reinforced with black steel bars should be completely coated while that using FBE coated steel bars should be coated up to a height of 1.5m from the grade level for protection against ingress of salt and water.
