The development of chloride infiltration models is essential for the assessment of the service life of concrete structures uncovered to marine environment .Simple models are consequent from Fick’s 2nd law of diffusion are at present the best way to guess chloride infiltration in practical situations. However these models need to be calibrating with investigational results. This paper presents an trial study where the parameters used in the infiltration model where calibrated to allow the guess of long term chloride content in concrete. The outcome showed that the concrete cover and concrete quality requirements stated in the present codes need to be increased so that an suitable service life can be achieve.

Abstract: The development of chloride infiltration models is essential for the assessment of the service life of concrete structures uncovered to marine
environment .Simple models are consequent from Fick’s 2nd law of diffusion are at present the best way to guess chloride infiltration in practical
situations. However these models need to be calibrating with investigational results. This paper presents an trial study where the parameters used in the
infiltration model where calibrated to allow the guess of long term chloride content in concrete. The outcome showed that the concrete cover and
concrete quality requirements stated in the present codes need to be increased so that an suitable service life can be achieve.

Abstract: This experimental study presents the difference in the strength of concrete when replace sand by quarry dust from 0% to 100% in steps of
10%. M20 and M25 grades of concrete were taken for revise keeping a constant slump of 60mm. The compressive force of concrete cubes at the age of 7
and 28 days were obtained at room temperature. Also the temperature effect on concrete cubes at 100oC on 28th day of cast was carried out to check
the loss of power. From test results it was found that the maximum compressive strength is obtained only at 50% replacement at area temperature and
net strength after failure due to hike in temperature was above the recommended strength value due to 50% replacement itself. This result gives a clear
picture that quarry dust can be used in concrete mixtures as a good alternate for natural river sand giving higher strength at 50% replacement.
