Rodded Bulk Density

-

                                                     Rodded Bulk Density

Image source:-indiamart.com


(1.) Metal measure of 3 liters capacity is used.

(2.) Fill the metal measure about 1/3 part full with thoroughly mix fine aggregate.

(3.) Temping of aggregate given 25 stokes using rounded end temping rod.

(4.) Now, added the second layer of aggregate using the similar quantity of aggregate and given 25 stokes.

(5.) The aggregate shall finally be filled to over flowing and temped 25 times.

(6.) Now, surplus quantity will remove using the straight edge.

(7.) Weight of metal measure filled with compacted aggregate =7.432 Kg.

(8.) Net weight of aggregate=Combined weight of metal measure and rodded aggregate-Weight of the                                                        empty metal measure

                                              =7.432 Kg - 2.686 Kg

                                              = 4.746 Kg

(9.) Rodded bulk density =Weight of compacted aggregate / Capacity of metal measure

                                         = 4.746 /3

                                         = 1.582 Kg/l

(10.) Take another set of reading and recorded in the observation sheet.

(11.) Average of two readings will be final value.

(12.) Percentage voids in aggregate = (Gs - R) /G * 100

         Where,

               Gs = Specific gravity of aggregate

                 R = Loose bulk density of aggregate

% of voids in aggregate = (2.60 - 1.398 )/2.60 * 100

                                       = 46 %

Note:- 

(i) Capacity of metal measure = 3 Liter

(ii) Width of metal measure = 15 cm

(iii) Height of metal measure = 17 cm

(iv) Temping rod dia.=16 mm

(v) Temping rod length = 30 cm

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.) The straightness test to be checked of RCC pipes through the straightness rods to collinear visible.   (8.) As per requirement 2% of hydro tests are to be checked as IS:458 of the total...

"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...
