  • Abstract:
  • The global consumption of natural sand is very high due to the extensive use of concrete in particular the demand of natural sand is quite high in developing countries owing to rapid infrastructural growth. In this situation some developing countries are facing a shortage in the supply of natural sand. The maximum strength of test 7 (40% dust +60% sand) was found as 16.44 N/mm2 and 28.66 N/mm2 for 7 and 28 days respectively which more among all the combinations. Thus cement, stone dust, sand and coarse aggregate proportion of 6:4.8:7.2:24 gave optimum result. For all mixes observed slump value lies between 30 to 45 mm. Which categories as low slump as for Indian standard Code of practice, hence such type of mixes may be suitable for Mass concrete; lightly reinforced sections in slabs; beams; walls; columns; floors; hand packed pavements; canal lining; strip footing.
