Cement is a vital building material used in the construction of roads, bridges, and buildings around the world. While most people are familiar with cement and its uses, few are aware of the secret ingredient that gives it its unique properties: Bogues compound.
In this blog post, we’ll explore what Bogues compound is, why it’s added to cement, the heat of hydration for both cement…

Applying for a Job in Construction and Civil Engineering industry and field is full of challenges and hardships. However, with proper planning you can get your dream job with ease. Today we are going to share you some of the very common and must to know Civil Engineering Interview Questions.
300+ Civil Engineering Interview Questions You must Prepare for
From these interview questions…
how should the guided bearings in piers of the curved region be oriented with respect to the fixed bearing in abutment?
May 27, 2016
To determine the orientation of guided bearings, one should understand the movement of curved region of a prestressed bridge. Movement of prestress and creep are tangential to the curvature of the bridge (or along longitudinal axis) while the movement due to temperature and…
What are the advantages of piers constructed monolithically with the bridge deck over usage of bearings?
May 27, 2016
Basically, piers constructed monolithically with the bridge deck are advantageous in the following ways:(i) Movement of the bridge deck is achieved by the bending deformation of long and slender piers. In this way, it saves the construction cost of bearings by using…
Diaphragms are adopted in concrete box girder bridges to transfer loads from bridge decks to bearings. Since the depth of diaphragms normally exceeds the width by two times, they are usually designed as deep beams. However, diaphragms may not be necessary in case bridge bearings are placed directly under the webs because loads in bridge decks can be directly transferred to the bearings based on…
In roller bearing for a given movement the roller bearing exhibit a change in pressure centre from its original position by one-half of its movement based on David J. Lee.
However, with sliding bearing a sliding plate is attached to the upper superstructure and the moving…
Why is the span length ratio of end span/approach span to its neighboring inner spans usually about 0.75?
May 27, 2016
From aesthetic point of view, an odd number of spans with a decrease in length in the direction of abutment is desirable. Moreover, spans of equal length are found to be boring. However, the arrangement of irregular span lengths is not recommended because it gives a feeling…
In the design of a simply supported skew bridge, which direction of reinforcement should be provided?
May 27, 2016
In the conventional design of steel reinforcement for a simply supported skew bridge, a set of reinforcement is usually placed parallel to free edge while the other set is designed parallel to the fixed edge. However, this kind of arrangement is not the most efficient way of placing the reinforcement. The reason is that in some parts of the bridge, the moment of resistance is provided by an obtuse…
