DETERMINATION OF DRY DENSITY OF SOIL IN-PLACEBY CORE-CUTTER METHOD

(I.S: 2720-XXIX)

Aim: To determine the Field density of Fine grained soil by using Core-cutter. (Itis less accurate than sand Replacement Method and recommended for wellCompacted soils.

Apparatus:

Core cutter / Dolly / Rammer.

Balance of 1 g accuracy.

Pallet knife, Straight edge, Steel rule, Pick axe etc.

Soil sample is termed as fine-grained if 90% by weight is passes through IS sieve4.75 mm.

Procedure:

Internal Volume ( Vc, cm3 ) of core cutter shall be calculated by takingDimensions to nearest to 0.25 mm (By vernier).

Cutter shall be weighed to nearest g. ( Wc, g )

A small area, approximately 30 cms square of the soil layer to be tested shallbe exposed and leveled.

Cutter shall be placed vertically on soil with dolly on top.

Cutter shall be rammed down vertically into the soil layer until only about 15mm of dolly protrudes above surface.

Care to be taken that cutter shall not rock sideways while hammering.

The cutter shall be dug out of surrounding soil by pick axe. Please take care soas to have some protruding soil mass from the lower edge.

Soil from both the ends shall be trimmed flat to the ends of cutter.

The cutter containing soil mass shall be weighed to nearest g ( Ws, g )The soil mass shall be removed from cutter and representative sample shall betested for water contents.

At least 3 tests are required to make average result.

Remarks – Often problem encountered when soil mass is dry and cutter is notproperly filled up or looses soil while handling. In such case test is to be doneby sprinkling water and testing after suitable lapse of time. Core cutter shall beremoved, trimmed and kept in polythelene bag to take it to laboratory. It shallbe weighed with cutter and any loose soil mass collected in bag.

Calculations :

Bulk Density Yb of Wet Soil is as below:

Yb = ( Ws – Wc ) / Vc , gms /cm3

Dry Density Yd is as below:

Yd = 100 Yb / ( 100 + w ) , gms /cm3 Where w = Water content %

PROCEDURE FOR COMPRESSIVE STRENGTH TESTING FOR CONCRETE

Aim : To establish Compressive strength of concrete sample for acceptance

Apparatus :Compressive Testing machine having adequate capacity.Weighing Balance.Measuring Scale.

Procedure :Remove the cubes required for testing from curing tank wipe clean of water andair dry them to surface dryness.

Stack cubes in sequence as per mix, dates, locations etc.

Record the actual surface area ( Sq cm)of the cube which will be in contact withplaten of CTM ( A in cm2 or mm2 ).

Weigh the cubes and record the weights in the register in kg.

Place the cube on platen centrally keeping trowelled side in front.

Position the top platen on cube surface. See that there is no gap left betweencube top and platen.

Load the CTM at desired speed without any shocks.( Pointer and needle shallmove together)

When crushing takes place in the specimen, needle will start falling back butpointer will remain at maximum reading.

Record the reading shown by pointer viewing perpendicular to the face of dial.( Load applied in kN or tonne- W)

Relieve the load from CTM. Remove the cube. Clean the platens.

Check the features of cube failure. Good failure is that cube mass retainedshall have concavity on sides. If failures are occurring consistently by crack developing only on one side it means cubes are eccentrically loaded. If cracksare always developed centrally means point load is getting applied due toConvexity of platens. Remedial measures are required to be taken for this.

Calculations:

Compressive Stress ( c ) in N / mm2 or Kg / cm2 as below :

c = Wx1000 /A in N/mm2 or Kg /cm2

Average of the set of Three or more cubes to be recorded (c’ ).

When three or more cubes from single batch/lot is tested, max variation isallowed +/- 15%. If any cube is showing more variation, result of that cube isdiscarded and average of two or more is to be taken.

Recording :

Record is generated as per the sample format given in chronological order.

PROCEDURE FOR FIELD TEST FOR SILT CONTENT IN SAND(Ref: A. M. Neville)

Aim : To determine Silt content in Sand by volumetric method field test.

Apparatus :Measuring cylinder 250 ml, Common Salt.

Procedure :Prepare 1% solution by mixing 10gms of common salt in 1litre of water.

Put this solution in measuring cylinder upto the mark of 50 ml.

Add Sand as received in the cylinder till its level reaches 100 ml.

Add Solution again so that the mixture reaches the level of 150 ml.

Cylinder top is now covered with the palm of hand and shake vigorously byturning upside down.

Then allow it to stand undisturbed for 3 hours.

Method Statement / CPWD Specification


Site Preparation

Prior to start of chemical treatment area(s) shall be made free from logs, stumps, timber off cuts, leveling pegs, roots of plants/trees etc. Soil treatment shall start when foundation trenches/pits are ready to take concrete/masonry on foundations and plinth area ready for laying the sub grade. Treatment shall not be carried out when it is raining or the subsoil water level is at the same or higher grade than the level of treatment. On the event of water logging of foundations. The water shall be pumped out and the chemical emulsion applied when the soil is absorbent.

Treatment of the excavated pits/trenches and backfill for foundation

The bottom surface and the lower 300mm. side surface of the excavated pits/trenches for foundations of masonry works and RCC plinth beams supporting such masonry works shall be treated with specified chemical emulsion 5 liters/Sqm. of the surface area. However, no such treatment shall be required in case of pits. Trenches made from RCC foundations supporting walls.

On completion of construction of masonry foundation the backfill in immediate contact with the substructure shall be treated in layers, of 300mm, with emulsion @7.5 Itrs/Sqm of the vertical surface of the sub-structure (i.e. 7.5X.3002.25 liters/meter of perimeter) for each side. The treatment shall he given after ramming of each layer of soil, by roding the earth at 150 mm centers close.

To the wall surface and working the rod backward and forward (parallel to the wall surface) arid then spraying the specified dosage of emulsion

directed towards the masonry surfaces so that the soil in contract with these surfaces in well treated with the chemical. After the treatment, the soil shall be tamped back into place. This shall be done for full depth of the fill.

For RCC walls and columns, the treatment as specified above shall start from a depth 500mm below the finished ground level, and shall be gone up to the FGL.

Treatment of Plinth/Basement and Apron

The top surface of the consolidated earth below the non-suspended floor slabs and the peripheral, aprons of widths up to 750mm, the bottom surface and side surfaces of the excavated pits for the basements shall he treated with chemical emulsion @ 5 liters/Sqm. of the surface area. Holes 50 to 75 mm deep at 150 mm centers, both ways. shall he made on the surface with 12 mm diameter mild steel rod and then emulsion shall, be sprayed uniformly over the area. At expansion joint locations, anti-termite treatment shall be supplemented by treating through the expansion joint @. 2.0 liters per linear meter of joint after the sub grade has been laid.

Treatment of Junctions of Plinth Filling Sand Wall/Column Faces shall he done after making a small channel 3OmmX3Omrn by making rod holes 150mm apart(up to the ground level) in the channel and then by moving the rod backward and forward to break up the earth. The chemical emulsion shall be poured along the channel (ZI 7.5 liters/Sqm. of the vertical wall/Column surface so as to soak the soil right to the bottom. The soil shall he tamped back into place after the treatment.

Treatment of Soil along External Perimeter of Building.

After the building is complete, the earth along the external perimeter shall be rodded at intervals of 150mm and to depth of 300mm. The rod shall be moved backward and forward. Parallel to the wall to break up the earth and chemical emulsion poured along the wall 7.5 liters/Sqm. of vertical surface (i.e. 7.5X0.300 = 2.25 liters/meter of perimeter). After the treatment, the earth shall be tamped back into place. Mixing shall he done as per manufacturing of approved company.
