Contour in Surveying | Direct And Indirect Method of Contouring | Civil Engineering

Contour in Surveying: A contour is a line that connects points of equal elevation on the surface of the earth. Characteristics of Contours: (a) Contour lines always form closed loops, although they may close either on the map itself or outside the map. (b) Contour lines are always perpendicular to the direction of the steepest slope. (c) The spacing of contour lines depends on the slope of the…

Workability of Concrete | Factor Affecting Workability

Workability of Concrete: Workability is the amount of work to produce full compaction. The important facts in connection with workability are: (i) If more water is added to attain the required degree of workmanship, it results in the concrete of low strength and poor durability. (ii) If the strength of concrete is not to be affected, the degree of workability can be obtained: By slightly changing…
