Abstract

Concrete research is the conventional strength-based approach to durability-centered in the past decades. Large number of structures are exposed to seawater either directly or indirectly. The experimental investigation is based on the concrete cubes buried in the three different types of natural and polluted (Seawater) soils. In the present study, design mix M-20 and M-30 are considered with slump between 70 to 100 mm with Ordinary Portland cement for concreting. For Compressive strength and non-destructive were tested on concrete for 7, 14, 28, 56 and 84 days. The effects of seawater and geotechnical properties on various types of soil were analyzed. The results of average compressive strength of concrete cubes are obtained after seawater intrusion between the ranges of 40.12 − 69.6 N⁄mm². The mean value of ultra-pulse velocity (UPV) is 22.9 and the average Rebound hammer (R) value for 28^th and 84^th days are 23 and 26, respectively at the temperature of 28±3̊°c. The results demonstrate that the influence of seawater affects the strength of the concrete specimens in soil due to loss of its stiffness.
