Core cutter test calculation method


 Core cutter test method 



 Operating instructions:- 

The core cutter method is used to determine the density and moisture content of embankment or foundation materials.


 Procedure:- 

Excavate the area to the prescribed depth, so that the excavated area has a horizontal and flat bottom surface measuring at least 0.4 x 0.6 m. Place the appliance with the drop weight in the hole and fix the sample ring with the crib in the holder that is fixed to the lower side of the guide bush. Set the guide bush vertically and allow the weight to fall as many times as is necessary until the edge of the holder is touching the bottom surface. Remove the appliance from the hole and dig out the sample ring, by inserting the shovel about 0.02 m beneath the sample ring. Skim off the lower side of the sample ring carefully with a sawing motion using the steel ruler. Make up for any loss of material at the lower side of the sample ring by applying a light pressure from your hand at the upper side of the sample ring by pressing the material to the lower side and skim off the excess material with the ruler. Place the sample ring on the flat metal plate and remove the crib. Skim off the excess materials carefully by applying a sawing motion.

Carefully brush off the exterior of the sample ring. Transfer the contents of the sample ring to a plastic bag. Use the brush to add the materials remaining in the sample ring to the contents of the plastic bag and close this so that it is airtight. Make sure the volume of the in situ materials is equal to that inside volume of the sample ring (V cm3).


 Mass and moisture content 

 Required materials: 

Balance, accuracy of 0.1 gr (art. no.: 98.01.03). Drying oven, at 110 ± 5 °C.

 Operation: 

The materials that were excavated or removed with the sample ring (c g) should then be weighed. Dry the materials at 110 ± 5 °C to a constant mass and weigh again when cooled (d g). Carry out precision weighings with an accuracy of 0.1 gr.

Calculation 

                                           c-d
Calculate the moisture content as   d      •  100% with an accuracy of 0.1%
Density: Make sure the volume of the materials in situ is equal to the inner volume (V cm3) of the sample ring. Determine the inner volume of the sample ring with an accuracy of 0.1 cm3

 Calculation 

                                                                                                       d
With an accuracy of 1 kg/m3, calculate the density as 1000 x     V    •  kg/m3.
The core cutter method is suitable only for materials that contain no stones.





 Core Cutter Test 

Formulas:-

Wet Density =   W.T of material / volume of core

Volume of core = πD2/4 * H

Moisture = 10 %

Dry density = (Wet density / M.C + 100)* (100)

Compaction = (Dry density / max dry density) * 100

METHODS OF TAKING OUT QUANTITIES

The quantities like earth work, foundation concrete, brickwork in plinth and super
structure etc., can be workout by any of following Three  methods but mostly use first two method:

A) Long wall - short wall method
B) Centre line method.
C) Partly centre line and short wall method


A) LONG WALL-SHORT WALL METHOD

In this method, the wall along the length of room is considered to be long wall while
the wall perpendicular to long wall is said to be short wall. To get the length of long wall or
short wall, calculate first the centre line lengths of individual walls. Then the length of
long wall, (out to out) may be calculated after adding half breadth at each end to its
centre line length. Thus the length of short wall Measured into in and may be found by
deducting half breadth from its centre line length at each end. The length of long wall usually
decreases from earth work to brick work in super structure while the short wall increases. These
lengths are multiplied by breadth and depth to get quantities.

last to methods definition in end Page of this page...
______________________________________________________

Example: - Workout The following quantities from the given data and sketch for a straight wall 20’ long.


 Earth work
     Concrete work
  Brick work in foundation and plinth
   Damp proof course
    Brick work in super Structure
   Cement plaster

B) CENTRE LINE METHOD

This method is suitable for walls of similar cross sections. Here the total centre line
length is multiplied by breadth and depth of respective item to get the total quantity at a time.
When cross walls or partitions or verandah walls join with main all, the centre line length gets
reduced by half of breadth for each junction.Such junction or joints are studied
carefully while calculating total centre line length. The estimates prepared by this method
are most accurate and quick.

C) PARTLY CENTRE LINE AND PARTLY CROSS WALL METHOD

This method is adopted when external (i.e., around the building) wall is of one
thickness and the internal walls having different thicknesses. In such cases,centre line method is
applied to external walls and long wall-short wall method is used to internal walls. This
method suits for different thicknesses walls and differentlevel of foundations. Because of this
reason, all Engineering departments are practicing this method.
