❖ Civil Engineers plan, design, construct, operate and maintain roads, bridges, dams, water supply schemes, sewerage systems, transportation, harbors, canals, dockyards, airports, railways, factories and large buildings.
✔Civil Engineers usually work in one of the following areas:
Structural,
Water resources,
Soil and foundation,
Transport,
Town planning, or
Construction.
✔A Civil Engineer may specialize:
Airport Engineer: An airport engineer-
specializes in preparing designs for airports, hangars and control towers,
supervises the construction, maintenance and repair of runways, taking into consideration factors such as weight, size and speed of aircraft,
advises contractors on technical problems during construction.
❖Geo-technical/Soil Engineer:
✔A geotechnical/soil engineer-
inspects proposed construction sites to work out soil and foundation conditions by conducting drilling and sampling programs,
✔oversees and participates in field and laboratory testing of soils, and makes sure that test equipment and machinery is properly set up,
prepares reports of test results and makes recommendations for the solution of engineering problems identified in test reports,
✔prepares specifications of soil mixtures for use in roads, embankments and other construction, and calculates and advises on the required slope at cuttings and the thickness of soil dams and retaining walls.
❖Harbor Engineer:
✔A harbor engineer-
designs and supervises the construction of harbor facilities such as breakwaters, navigation aids, navigation channels, jetties, wharves, heavy-duty pavement surfaces, cargo sheds and bulk handling plants for grain, ore and other cargo;

Slump Test of Concrete-Cone Test Procedure | Workability of Concrete Slump test procedure is to determine the workability of concrete. One of the major problems that you had faced in your field work is concrete compaction during mixing.After mix design, you may have doubt, is this design will be ok? Yes, your design willl be ok in terms of strenght point of view of concrete.But the main problem arises when the mixing of fresh concrete, the compaction of fresh concrete will be very tough.In this situation, you can add some plasticizers without affecting your water-cement ratio or cement-aggregate ratio. Before adding plasticizers or superplasticizers to your fresh concrete, you need to check the workability of your concrete.The slump test is used for checking the workability of concrete.Let us check how can we do slump test of fresh concrete. Apparatus used for cone test procedure 1)Measuring scale 2)Tamping rod 3)Base plate 4)Nonporous base plate 5)Mould for slump test. ...
