Civil Engineering Home

Engineering is a term applied to the profession in which a knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied to the efficient use of the materials and forces of nature. Engineers are the ones who have received professional training in pure and applied science.Before the middle of the 18th century, large-scale construction work was usually placed in the hands of military engineers. Military engineering involved such work as the preparation of topographical maps, the location, design, and construction of roads and bridges; and the building of forts and docks; see Military Engineering below. In the 18th century, however, the term civil engineering came into use to describe engineering work that was performed by civilians for nonmilitary purposes.

Civil engineering is the broadest of the engineering fields. Civil engineering focuses on the infrastructure of the world which include Water works, Sewers, Dams, Power Plants, Transmission Towers/Lines, Railroads, Highways, Bridges, Tunnels, Irrigation Canals, River Navigation, Shipping Canals, Traffic Control, Mass Transit, Airport Runways, Terminals, Industrial Plant Buildings, Skyscrapers, etc. Among the important subdivisions of the field are construction engineering, irrigation engineering, transportation engineering, soils and foundation engineering, geodetic engineering, hydraulic engineering, and coastal and ocean engineering.

Civil engineers build the world’s infrastructure. In doing so, they quietly shape the history of nations around the world. Most people can not imagine life without the many contributions of civil engineers to the public’s health, safety and standard of living. Only by exploring civil engineering’s influence in shaping the world we know today, can we creatively envision the progress of our tomorrows.

    i am a 2nd yr student of civil engineering i want complete notes for MOS (mechanics of solids) all 5 units…plz send to it my mail

    In Raft footing when the 75% of area of foundation cover & load of structure is very high, there is both sagging & hogging Bending Momment Takes place. upper steel takes place sagging bending momment & lower steel takes place hogging bending moment due to soil upword flow ie. Invers of Terrace slab

    What is the fines grade for plastering sand ?

    avinash ranjan
    cube of M45 has been tested in lab ,it is found that 7 days strength is 52mpa can this mix design can be rejected or on which is codal provisional .

    dear avinash no one can understand concrete how it behave in different type op conditions, if your m45 cube gave 52 mpa strength of several samples at 7 days its too high. we can imagine up to 100% strength if our quality control is excellent. you may reduce your cement content.

      Dear send me this mix design.
      if really happens it is so good.

    Does tidal energy harvesting comes under hydraulic engineering?

    I want some journal papers of hydraulic engineering..

  • yogendra kumar sahu November 3, 2015 at 10:17 am

    i study in diploma in civil in 2nd year. how the find out the tensile strength of cement & steel.

    • Teja reddy May 11, 2016 at 11:16 am

      you can’t find the tensile strength of cement directly, it can be found by conducting compressive strength of cement on cement cube of size 7.07 cm using 1:3 ratio of cement to sand and then from that u can take the tensile strength as 15% of compressive strength

      • Teja reddy May 11, 2016 at 11:21 am

        and U can find the tensile strength of steel by using the universal testing machine(UTM), In that a steel bar is placed of known cross sectional area and then on that a tensile load is applied with the help of loading device in the UTM and then tensile strength is = load/ cross sectional area

      It’s nothing but refer IS 456:2000

  • Raviteja mukkara November 11, 2015 at 5:58 am

    Hi friends this is raviteja mukkara vvvv happy and good afternoon.ok concrete is a mixer of cement,course and fine aggregate it is general one OK my ? is Y we are not using wood and small dry tree pics in concrete

    • hasan November 29, 2015 at 3:50 pm

      Friend the major reason is that the cement will not form a better bound with the pieces. Even if u cut it in an appropriate size then in the long run it will deteriorate due to water, termites, temperature and humidity etc.. And also the wood is not in as plenty as stones.

    • Prakash December 2, 2015 at 7:07 am

      Because wood is a bio degradable material and it will decompose over time. It will not take any load

    • ashok March 25, 2016 at 10:04 pm

      Hi sir good mring
      Wood pieces are weak in compression

  • MARISELVI.M December 1, 2015 at 11:40 pm
