Abstract: Depletion of natural resources and new Environmental laws are preventing restrictive use of natural sand, thus the demand for quarry sand is increasing concrete construction. The properties of quarry sand depend upon basalt rock type from which it is derived. There is need to bring out suitable combination of natural sand and quarry sand along with other admixture to make concrete of desired performance. The present research is aimed at deciding the combination through gradation of aggregates, workability of concrete and compressive strength...........

Keywords: Cement, Fly ash (FA), Quarry sand, Workability.

Abstract: In India many foundries have followed conventional and manual operations. Foundry industries suffer from poor quality and productivity due to large number of process parameters combined with lower penetration of automation and shortage of skilled worker. Mould shifting, sand inclusions, poor surface finish, shrinkage, porosity, cold shut and flash are common casting defects in casting. Since casting process involves complex interaction among various parameters and operations related to metal composition, method designs, melting, pouring, shake-out, fettling and machining and hence need to improve. This Paper prescribes comprehensive review of work pertaining to process improvement techniques used for defect minimisation in casting.

Keywords: Casting design, Casting defect, Cause of defects, Yield improvement, Process improvement.

Abstract: The present study concerned with the impact of velocity slip on MHD peristaltic flow through a porous medium with heat transfer is investigated. The relevant equations of flow with heat transfer have been developed. Analytic solution is carried out under long-wavelength and small Reynolds number approximations. The expressions for the stream function, temperature and the heat transfer coefficient are obtained. Numerical results are graphically discussed for various values of physical parameters of interest.

Keywords: Peristalsis, MHD, porous medium, slip flow, compliant walls.
