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.

Uses of partial differential equation in civil engineering?
Civil engineers use partial differential equations in many different situations. These include the following: heating and cooling; motion of a particle in a resisting medium; hanging cables; electric circuits; natural purification in a stream.
What is the major difference between a friction crane and a hydraulic crane?
A friction crane is an older model like an American 9210 who's boom controls are gear/ clutch driven. Engaging the clutch and throwing the gears requires a very stout frame and they typically have much stiffer booms and can tolerate a lot more abuse.... They are good for rough lifting operations like pulling pile or pile driving.
Hydraulic cranes are there modern counterparts who's boom is controlled by hydraulic pistons which have a much lighter, more delicate touch to the controls and are much better in "heavy lift" operations where you need precision movement.
How tall is the Mackinac bridge?
The height of the main towers of the Mackinac Bridge above the water is 552 feet.
What do you mean by rowlock header soldier sailor shiner or rowlock stretcher and stretcher?
Masonry units can be laid in several positions. For example, think of a pair of dice. Each face has a separate number on it. A brick is similar, but there are only 3 faces that are different sizes (since the direct oposite side is the same dimension) and each of those faces can be installed in two directions for a total of six different positions. These positions are called stretcher, header, rowlock, shiner, soldier, and sailer.

What does disobeyed traffic control device mean?
It's fancy wording for one of two things. (1) You ran a stop sign. (2) You ran a red light. Either one is a traffic violation, and gets you a ticket.
Any device that can legally be used to control traffic such as a sign or a flashing light is also a traffic control device.How do you encase steel beams in concrete?
When designing composite members, one first needs to consider the properties necessary of the beam, in response to the expected loading. Basically, what will the beam experience? Is it flexural loads, or compressive/axial forces? The loading will greatly influence how the steel moves with the concrete as they are bonded together, and whether or not some bonding grout or other bonding agents are needed.
There are many ways you can encase a steel beam in concrete, but let's assume one case: you have a beam that will take mainly flexural loads and that you want the steel beam to be fully encased by the concrete (no steel showing on the outside, in other words). What I would do is install formwork to encase the conecrete on a suitable, hard surface. Then, after having selected the right steel section for the beam, I would drill small holes in the beam flanges in order to attack galvanized anchors/wires. These can be placed anywhere you like, as long as there are not too many of them. These anchors, typically two on each side of the beam's total length, could be attached to cables or chains that are, in turn, attached to hoists or engine-mounts that can lower the beam carefully into the desired position inside the concrete formwork. Make measurements for how low the steel beam should sit in the concrete, and doublecheck your measurements: after this, there's no turning back. Add concrete to the mix and, if you have concrete vibrators, use them to allow for proper concrete mix settlement and extraction of air bubbles from the mix. This will also ensure a good bond between the concrete and the steel. Then, let the concrete set for 5-7 days and store it in a humid room or location (humid, not wet/rainy). Lastly, remove formwork and cut the wires/anchors that are sticking out of the concrete. I would put some appropriate sealant on these locations, as they can be sites for water infiltration in the concrete. Their inner portions cannot be removed at this point. So there you have it, my approach to encasing steel beams in concrete.
How do you calculate kg of steel reinforcement in one cubic meter concrete?
it would depend entirely on the rebar design.....
How much is one bag cement in the Philippines?
I have no Idea maybe you can look on google and they might tell you or maybe ask your science teacher.
What are true slump and shear slump in slump test?
A shear breaks off or crumbles. A slump stays together however it will slump down.
How do you Calculate for hourdi blocks in roof slab?
Length of the slab in which the houdry blocks are facing ( hadder face) divide by two will give you ans the substract 1 from the ans ...[ l/2=ans - 1 ]
Is partition wall of a building live load or dead load?
Partitions walls are taken as live (imposed) loads, not dead loads. This is because they are structurally redundant and can be moved around as the use of the building changes over time. For this reason, partition loads are modeled as area loads, rather than line loads, because their positions may change.
On the other hand, a load-bearing masonry wall that is structurally important would be modelled in its position and as a dead line load.
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
What is the principle of compass surveying?
The prismatic compass is a type of compass use for survering a land.
What are the advantages of float glass?
Soda glass is normal glass! it is the cheapest eg compared with pyrex glass for heat resistant ovenware. Strictly soda glass may be just sand and soda fused together.The soda makes the glass water-soluble, soft and not very durable. Therefore lime is added increasing the hardness and chemical durability and providing insolubility of the materials. Nobody makes just soda glass for centuries and over the years soda lime glass is often called just soda glass.
Soda-lime-glass, is the most prevalent type of glass, used for windowpanes, and glass containers (bottles and jars) for beverages, food, and some commodity items. Glass bakeware is often made of tempered soda-lime glass.
Soda-lime glass is prepared by melting the raw materials, such as sodium carbonate (soda), lime, dolomite, silicon dioxide (silica), aluminium oxide (alumina), and small quantities of fining agents (e.g., sodium sulfate, sodium chloride) in a glass furnace at temperatures locally up to 1675°C. The temperature is only limited by the quality of the furnace superstructure material and by the glass composition. Green and brown bottles are obtained from raw materials containing iron oxide. Relatively inexpensive minerals such as trona, sand, and feldspar are used instead of pure chemicals. The mix of raw materials is termed batch.
Soda-lime glass is divided technically into glass used for windows, called float glass or flat glass, and glass for containers, called container glass. Both types differ in the application, production method (float process for windows, blowing and pressing for containers), and chemical composition . Float glass has a higher magnesium oxide and sodium oxide content as compared to container glass, and a lower silica, calcium oxide, and aluminium oxide content.From this follows a slightly higher quality of container glass concerning the chemical durability against water, which is required especially for storage of beverages and food.

One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete.
These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over
What is scarification in road construction?
It is cold planing - or milling - of the asphalt surface. This is done for a number of reasons including the following:
-Removing ruts or bumps or irregularities in a roadway before resurfacing.
-Lowering a road surface that is to be resurfaced or treated so that it fits the profile of adjacent roads.
-Removing existing asphalt that is found to be unacceptable.
