Abstract: This paper presents the influence of different types of cement CEM-I, CEM-II/A-M, CEM-II/B-M, CEM-III/A as per BSEN-197-1 & pozzolonic materials Fly ash & GGBS on chloride penetrability to Concrete. Chloride-induced corrosion is one of the main mechanisms of deterioration of reinforced concrete structure & affecting the long-term performance of structures. So in this research work a detail experimental study has been conducted on penetrability of chloride ions in concrete by using Rapid chloride penetrability test (RCPT) as per ASTM C-1202 & calorimetric test by using 1% AgNO3 solution. The outcome of this research work shows that concrete made with Blast furnace slag cement CEM-III/A, Portland composite cement CEM-II/B-M & also concrete made with pozzolonic materials 25% Fly ash & 70% GGBS shows minimum penetration of chloride ions .Thus resistance of chloride penetrability to concrete with different cement is of following decreasing order CEM-III/A > CEM-II/B-M > CEM-II/A-M > CEM-I. So in this research work it shows that concrete made with cement having higher amount of pozzolonic materials [3] & also concrete made with partial replacement of normal Portland cement CEM-I with higher % of GGBS & Fly ash shows minimum penetration of chloride ions.
