STRENGTH AND CORROSION RESISTANCE OF CONCRETE USING COPPER SLAG AND SILICA FUME by Maninderjeet Singh
Abstract
Presently world is seeing the advancement of extremely difficult and challenging structures, cement and fine aggregate as utmost essential which generally castoff basic substantial which own good quality. As in the conventional concrete cement which is a water based binder used to hold all other building material together, on the other hand fine aggregate used to occupy most of the volume present in concrete. Both the ingredients emits approximately equal amount of natural resources. In this manner to conquer the above harmful impacts, need to replace these materials with the newer one having same properties and should be economical. The inclusion of pozzolanic material with the OPC a century old practice is a substitute to these material in the construction monopoly. Additionally over the most recent couple of decades, there dated an increasing worldwide problem of deterioration of reinforced structures, brought about fundamentally by the degeneration of steel reinforcement embedded within the structure. There are a few factors which kept in mind to minimize the corrosion procedure in various type of inservice structures such as good concrete quality, surface conditions, and other indirect factors. The purpose of the research is to present the study on strength along with corrosion resistance of concrete employing copper slag (CS) and silica fume (SF). The objective of our study was to resolve the Compressive strength, split tensile strength and the corrosion resistance of concrete using Accelerated corrosion test with impressed voltage (ACTIV). The outcome displays that the adoption of CS and SF produces concrete with superior results than the conventional concrete at different substitution level of CS and SF with the fine aggregate as well as the cement. Furthermore the chloride convinced corrosion resistance of concrete measured with ACTIV technique is highly improved with combined use CS and SF respectively. Therefore the corrosion inhibition of concrete with both the pozzolans is higher than the normal concrete. From this we can concluded that the use of CS and SF is effective in exaggerate the chloride induced corrosion
of concrete.
