Civil Engineering
Civil Engineering is a profession of designing and executing structural works that serve the general public, like houses, buildings, roads, etc. A Civil Engineer is an engineer trained in the design and construction of public works, such as bridges or dams, and other large facilities.

What is the Concrete hollow block size in the Philippines?
The hollow block sizes in the Philippines are the following:
- 40cm (length) X 20 cm (width) X 4 in (thickness)
- 40cm (length) X 20 cm (width) X 5 in (thickness)
- 40cm (length) X 20 cm (width) X 6 in (thickness)
Why do we prefer concrete dam in V shaped area?
floods less land, uses less materials (concrete, steel...) to construct dam
What are the types of non load bearing walls?
Non load bearing walls are walls that the weight of the roof is not supported on. Any wall that runs parallel will roof joists will be non load bearing.
What tor stand for in tor steel?
TOR is a Brand Name originally marketed by TORISTEG STEEL CORPORATION of Luxembourg, Germany.
How much does a yard of asphalt paving material weigh?
For what thickness and width? Typical finished and compacted asphalt concrete weighs 140 to 150 lbs per cubic foot. The density depends on how compact it is and what type, size, and percentage of aggregates are used.
So a one yard by one yard cut of a typical local road (4" thickness) should weigh close to 450lbs
How do you use dumpy level to find the relative heights?
Dumpy level provides a horizontal line (parallel to earth's curvature); you can read the scale by holding it normal to the ground level. Take separate readings for separate points then compare them
What is a example of post reinforcement pause?
Post-reinforcement pause is a pause in responding that typically occurs after the delivery of the reinforcer on fixed-ratio and fixed-interval schedules of reinforcement.
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
What are the uses of alloys in daily life and how are alloys made?
Every metal thing you use in your daily life is made from an alloy. Alloying metals can make a metal that exactly meets your needs - if you need a metal that melts at 100 degrees C, or one that's harder than granite, alloying will let you fill your requirements.
Making an alloy is a three-step procedure. Metallurgists and engineers will determine the need for a new metal, its characteristics, and the mixture of base metals that will meet the requirements of the new metal in the most economical manner. Next, they will make a small batch of the alloy in a laboratory and test it to see if it works the way they want. If it does, they'll go to a metal plant and make a large batch to see if it works like it did from the small batch.
It refers to the go / no go boundry, a 5 mm sieve wont let anything larger than 5 mm through, but anything less will pass through.
What is the formula for moment of a force?
Turning moment (Nm) = Force (N) x Perpendicular Distance from the pivot to the line of action of the force (m)
What are the different names of civil engineering?
Just Civil engineers cause be bring civilization to human life through engineering works
What is the benefits of knowing Young's Modulus for concrete?
Young's modulus describes the relationship between stress (sigma) and strain (epsilon) in a material that obeys Hooke's law.
Concrete is such a material and knowing this property allows one to plan and design the use of concrete as a building material safely.
Compare accuracy and precision?
It is best to think of this in terms of a shooting target, when the bullet hits close to the bulls-eye, this is accuracy. In other words it is how close your result is to what it is supposed to be. Precision is about the grouping, if you fir 5 shots and one hits the bulls-eye, then on hits far above it, one below it, one to the left, and one to the right, they are not close and therefore your precision is off. However even if you hit as far from the bulls-eye as possible, but all five bullets hit in the same area, then this is precision. In other words if all of your results of your experiment always turn out about the same, it is precise.
How you calculate the capacity of cement silo?
Dear Friend, calculate the volume of the silo ie., nothing but the capacity you required.
Why fineness modulus of coarse aggregates is more than that of fine aggregates?
how does the fineness modulus of aggregate affect the strength of concrete
What is the maximum retention amount in construction contracts?
Limit of retention is the maximum amount that can be retained in the construction contract. Suppose the retention % is 5% and limit of retention is 10%. On a contract value of Rs100.00. The first claim amounts to Rs20.00. Retention is Rs1.00 and net payment is Rs 19.00
Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
What is specific gravity of sewage?
Anything on Earth experiences the same gravitational force. Earth's gravity is 9.8m/s2 on all objects (slightly greater near the equator and slightly less further from it). This means that every second an object is falling, it's speed will increase by 9.8 meters per second. This is not taking air friction and other such things into account.
