Question

Identify the given joint in Concrete Structures.

(a) Horizontal construction joint

(b) Expansion construction joint

(c) Vertical construction joint

(d) Water tank joint

This question was addressed to me during an interview for a job.

My enquiry is from Joints in Concrete Structures topic in section Cement Concrete Construction of Construction & Building Materials

Answer 1

The correct choice is (c) Vertical construction joint

To explain: The construction joint maybe horizontal or vertical. For an inclined or curved member of the joint should be at right angle to the axis of the member. It is necessary to determine the location of construction joints well in advance for the viewpoint of structural stability.
