  Saw Dust Ash as Partial Replacement for Cement in Concrete

  replacement material in the production of structural grade concrete and mortar. Elinwa et al. (2008) assessed the fresh concrete properties of selfcompacting concrete containing sawdust ash. Elinwa and Mmoodb (2002) considered ash from timber waste as cement replacement material. The present study considered both fresh and

  Sand Cone Test ( Field Density Test By Sand Replacement

  The sand cone method is used for field density test in highway construction. In the field, the dry density test is performed to check the compaction of layers. Compaction is most beneficial for the preparation of sub base grade and different pavement layers and in the production of embankment in order to increase the steadiness and to lower settlement .

  Moulding sand SlideShare

  Backing sand: Backing sand is the bulk of the sand used to back up the facing sand and to fill up the volume of the flask. It consists mainly of old, repeatedly used molding sand which is generally black in color due to addition of coal dust and burning on contact with hot metal. Because of the color backing sand is also sometimes called black sand. The main purpose for the use of backing sand

  Suitability of Quarry Dust as a Partial Replacement of

  Large quantity of the quarry dust gets produced annually in the quarries during the extraction of the crushed coarse aggregate. As a result, disposal problems of this material gain significant momentum as these disturb environmental systems also. Nowadays many of the countries like India is facing problems of ban on the extraction of sand and lacunae in procuring of fine aggregate, which is
