Comparative Study of Rapid Chloride Penetration Test (RPCT) on Self Compacting Concrete (SCC)

Abstract

Abstract: To check resistance to chloride ions penetration, we used Electrical resistivity techniques to give an indication of the relative permeability of concrete. The ASTM C 1202 (Standard Test Method for Electrical Indication of concrete’s ability to resist chloride Ion Penetration), more commonly known as the rapid chloride permeability test (RCPT). Self-compacting concrete (SCC) is a very fluid concrete and a homogeneous mixture. In this research work, M40 grade of concrete mixes were made using IS 10262:2019 method. The fresh and harden properties of SCC was taken at the ages of 3,7 and 28 days. After experimental investigation, we can conclude that SCC was more workable than the normal concrete and it did not show any major reduction in compressive strength up to 2% replacement of Super plasticizer. The RCPT is performed on Normal & SCC mix after 28th days and SCC mix showed less values of charges passed than that for the normal concrete mix. Hence, SCC has more resistance to chloride ions penetration.
