Proctor Test for Compaction of Soil

-

 Proctor Test for Compaction of Soil

Image Source: theconstrutor.org


Compaction is a artificial process in which expulsion of air is done by means of mechanical means. The dry density is maximum at certain moisture content, that moisture content which is called optimum water content. A curve is drawn between the water content and the dry density to obtain the maximum dry density and optimum water content.

Dry density of soil=Wet density/(1+W)

Where, W=Water content

Apparatus Required:-

(i) Take balance, weight=10 kg, where least count=1 gm

(ii) Rammer, weight= 4.9 kg, where Fall=450 mm

(iii) Proctor mould, Dia.=150 mm, Depth=127.3 mm

(iv) 37.5 gm GI sieve is used. (Note-If soil is coarse, then 37.5 mm sieve is used and for other soil 19 mm sieve is used)

(v) Total soil sample taken=30 kg

(vi) We have taken 6 kg samples of soil in 5 nos. of tray.

Test Procedure:-

(i) Mould weight taken=6175 gm

(ii) 4 % moisture to be added i. e. 6000*4/100=240 gm

(iii) 240 gm water is added and mix properly. In that time, wear gloves.

(iv) After mixing the water with soil, we will separate soil into 5 parts in the pan.

(v) Fill the soil in mould in 5 layers and each layer 55 blows used.

Also Read: Compressive strength of brick

(vi) Firstly one part from pan is used to fill the mould and 55 blows will used. Similarly, second, third, fouth and fifth part will filled and also 55 blows is used in each layer.

(Note-Here, soil is granular. So, big mould is used and if soil is sandy, then 100 mm mould will used.)

(vii) Now, unscrew the mould and after unscrew we will make plane the mould surface through strater (30 cm) scale.

(viii) Now, weight them. Weight=10.790 kg

(ix) Now, moisture will found with the help of small size container.

(x) weight of empty container is taken.

(xi) Small part of soil is taken from mould with the help of knife/blade.

(xii) Fill the container. Now, weight =153 gm

(xiii) Now 6% water is added for second sample. i.e. 6000*6/100=360 gm

(xiv) Procedure will similar. Repeat continuously.

(xv) It will also unscrew and make plane with the help of strater (scale). Now, wt.=11.060 kg

(xvi) Small container B-2 will take and small amount of soil is kept. Now, wt=153.60 gm

Note:- Same procedure will repeat for third, fourth and fifth sample.

(xvii) Now, fill the format.

(xviii) All containers (small size)will  kept on a tray and also kept in oven. Temperature =105-110o c

(For 24 hours)

(xix) Now all containers are remove from oven and then weight and fill into format.

(xx) For graph platting we will take a graph.

Important Points SOP (Standard Operating Procedure) During the Inspection of RCC NP4 Pipes: -    Image-Hydro Test (Photo Credit: Ritesh Raj) (1.) Firstly, approved QAP will be checked.  (2.) ID marks should be marked on the inner and outer sides of pipes.  Image-ID Mark (Photo Credit: Ritesh Raj)  (3.) To check the inner and outer diameter of pipes.   (4.) Smooth finishing and before dispatch of RCC pipes cement slurry or grouting where required.   (5.) Load test is required for RCC pipes as per IS codes. It is different for each dia, of RCC pipes.  Image-Plate Load Test (Photo Credit: Ritesh Raj)   (6.) Concrete mix design checked and in which cement content, cement brand, and water-cement ratio should be checked.  (7.)

"Sewer Network Analysis"

The word sewerage is made from sewer. The word sewer indicates the usable water which is received from kitchen, bathroom and outfall from toilet/W.C. Every large or small city was held at sea, river and lake and it was planned at initial stage of the project planning, that the dirty water of homes and industries was dumped in that water source easily. Many years passed the dirty water from these utilities are dumped in the nearest source and that source water was make too poisons. Many aquatic life is survive in water and when dirty water is mixed with water source the biological cycle was affected and fishes and other animals population was decreases. Image Source:Pexels.com In that case population of human is also increases continuously and after that level of water source was decreases and we faced many problems continuously. Then sewer network is introduced. Outlet from all homes are connected to lateral lines means the water of kitchen, bathroom and water closet are co...
