Alternative to Natural Sand is Manufactured Sand; M-Sand was used as having a bulk density of 1.75kg/m3 with specific gravity and fineness modulus around 2.73 and 4.66, respectively. Dry density measurements are also useful for determining degree of soil compaction. Various types of field density tests are being practiced in different parts of the world for the evaluation of in-situ soil compaction and knowing the relative degree of Compaction.. FDT, Full name is Field Density Test, is a Quality Control test carried out at the site for knowing the increased Compaction or Density or achieved at a site on the soil layer. The basic purpose of field density test calculation is to know the density achieved at site with the help of mechanical compaction equipment.

[1] Standard Values of Concrete Density. consequential or punitive damages, however caused regardless of the theory of liability, A common type of concrete pump for large scale construction projects is known as a boom concrete pump, because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.It is attached to a truck or a semi-trailer.

The measurement of air content in fresh concrete of normal density is typically performed using the pressure method ().Another useful test is ASTM C 173.However, the pressure method is frequently preferred because it is relatively fast. Mix the cement and fine aggregate on a watertight none-absorbent platform until the mixture is thoroughly blended and is of uniform color. The standard aggregate relative density can be defined as mass divided by an equal volume of liquid like water.
