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 ordered quantity.  Image-Hydro Test (Pressure Release) (Photo Credit: Ritesh Raj)

Important terms on the basis of IS Codes

-
Image
In this article,I am presenting few important most important questions with their answers, taken from various IS codes.These questions could be of your great help for your interview and general awareness about civil engineering. Please go through it.I hope it will expand your knowledge. (1.) For most work, 20 mm aggregate is suitable. (2.) The plumb shall be distributed evenly and shall be not closer than 150 mm from the surface. (3.) In concreting, the PH value of water shall be not less than 6. Image Source:Pexels.com (4.) The modulus of elasticity of steel shall be taken as 200 KN/mm 2 (5.) The characteristic strength is defined as the strength of material below which not more than 5% of the test results are expected to fail.

In this article,I am presenting few important most important questions with their answers.These questions could be of your great help for your interview and general awareness about civil engineering. Please go through it.I hope it will expand your knowledge. Image Source:happho.com (1.) Bleeding :- Diffusion or running of concrete through form work. It indicates the more water cement ratio and fine particles. (2.) Curing :- Curing is done to supply of necessary water required for hydration and stop or prevent the loss of moisture from the surface of the concrete. Image Source:Gharpedia.com Steam under pressure curing helps to gain the early strength of the concrete but does not provide the increase in compressive strength neither reduces the shear strength of the concrete. (3.) Rebound hammer(Schmidt hammer) test gives only approximate estimation of strength of the concrete specimen.

"Sewer Network Analysis"

Image
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
