Can a 66000 pound concrete truck safely drive over a 4' diameter reinforced concrete pipe with 4 inch walls buried 1' below in average compacted soil?
This all depends on the class of Reinforced Concrete Pipe (RCP) it is. Typically the manufactorers of RCP recommend one foot of compacted fill over a pipe for construction traffic. As long as the material is not wet I would drive over it any day.
What is grillage footing?
A framework of heavy timbers, steel, or reinforced concrete beams laid longitudinally and crossed by similar members laid upon them to spread a heavy load over a larger area, esp. for use where the ground is not firm.
What is result of more reinforcements used in structure?
The structure is called a over reinforced concrete or structure. The structure can fail without warning. Discuss why managers she would always t ry to use positive reinforcement instead of negative reinforcement
Who invented reinforced concrete?
Thomas Edison promoted it extensively but did not invent it. In America, the techniques of Reinforced Concrete were greatly improved over the earlier French pioneers by Earnest L. Ransome. His system created the first large skyscraper of 15 stories, the Ingalls Building in Cincinnati, Ohio in 1903. Edison later partnered with Ransome to expand and explore its potential.Earlier, it is Joseph Monier getting the first patents in France for what will become the building medium, Reinforced Concrete in 1867. Monier was actually building on techniques that were first developed for other purposes by Joseph Louis Lambot as early as 1848. It is believed that in fact, Lambot recieved the first patents, possibly in Belgium, and he exhibited a reinforced concrete rowboat in Paris in 1855. Monier, a gardener in charge of the Orange trees at the Palace of Versailles may have seen Lambot's boat and used the techniques to make outdoor pots and large planters, getting the first patents for them in France in 1867. Monier continued to expand these patents for other stuctural use.
Can you pour a concrete sidewalk over top of another existing concrete sidewalk?
No do to the concrete settling the concrete on top would split
What is the difference Between under reinforced section and over reinforced section?
When the maximum stresses in steel and concrete simultaniously reaches allowable value the section is called balanced section when the %of steel in a section is less than that required for a balanced section it is under reinforced section when the %of steel in a section is more than that required for a balanced section it is over reinforced sectionover reinforcement is as per section design I.e Ast1+Ast2>Ast Ast1+Ast2

Why iron metal is used in building construction?
It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.
Why it is undesirable to design over reinforced sections?
There are two basic reasons 1. In over reinforced section failure happens due to concrete which is sudden without any type of warning like bending or deflection.... 2. Steel is one of the most costly material used in construction work so from the economical view it is also undesirable to provide over reinforced section...
Can cinder be used as fillers in sunken areas of Reinforced cement concrete?
Yes, Cinder concrete cab be used for sunken portions of the slabs over water proofing. Pandu R Reddy.Bijjam M.Tech(structures)
What material is taking over the role of metals in industry?
truly speaking the most used material in replacement of metals in construction is the reinforced concrete or the prestressed concrete, but they are instances where metals can not be replaced like in electrical installations. concrete is the second widely used after water
Is the under and over shotgun safer than a side by side shotgun?
Yes, if it is unloaded while the other is not.
Which reinforcement is safe under or over reinforcement?
Under reinforcement is safe because in this case steel fails before concrete.
What is grillage footing?
A framework of heavy timbers, steel, or reinforced concrete beams laid longitudinally and crossed by similar members laid upon them to spread a heavy load over a larger area, esp. for use where the ground is not firm.
How has transport got safer over the years?
transport has got safer over the past years as we now have seatbelts and air bags in our cars now and i feel much more safer!
