Murugaiyan Professor, Department of Civil Engineering, Pondicherry Engineering College, Puducherry, India ABSTRACT Locally available Red soil were used for the experimental analysis to study the effects of seawater impact in concrete structures with comparison of normal water in terms of its strength properties and changes on the behavior of Red soil. M-20 & M- 30 concrete cubes were casted with 0.45 water-cement ratio. Casted Concrete cubes are buried in red Soil near Costal zone to observe the Compressive strength and NDT during 28th day and 84th day with addition of fly ash class-C of two different proportions 20% & 30%. Totally 72 specimen were cast with normal water. The highest value of compressive strength obtained is 35.13N/Sq.mm during 84th day for Seawater curing in addition of fly ash class-C and lowest value is 15.57N/Sq.mm during 84th day for seawater curing without fly ash Keywords: Compressive Strength, Red soil, Partial replacement fly ash, Normal water, Seawater, NDT.

INTRODUCTION A variety of soil classification systems have been developed to describe the suitability of soils for specific types of land use and the natural ability of the soils to tolerate factors leading to their degradation. These inherent soil characteristics vary within and between continents, regions, and landscapes Inherent differences in soil properties arise from the influence of the generally accepted factors of soil formation, namely climate, time, vegetation, parent material
