What three things happen to the Earth's crust when earthquakes occur?
Three things that happen to the Earth's crust when earthquakes occur include, a release in energy, plates sliding past one another, and fractures developing in the crust. Not all of these things happen at the same time and which occurs depends on the strength of the earthquake.
Do mudslides occur often?
they only happen in may
Where does erosion occur the most?
It mostly happen in the Ocean
What time of year do tornadoes occur?
Tornadoes can happen at any time of year but occur most frequently in spring an early summer.
Where does coastal erosion occur the most?
It mostly happen in the Ocean
What problems can occur if the contractors use faulty concrete?
There are many possible faults and resultant problems that can occur in concrete. Most relate to a reduction in the final strength of the concrete.
What is the difference between the setting and hardening of concrete?
Setting indicate the beginning of stiffening of concrete ,in this case the concrete has not any strength and any cracks if occur can be re unit the concrete in this state just like a dough bread afar setting the concrete stiff and become hard and get strength and any cracks if happen cant be re unit

When is reinforcement-bar required in footings?
Two reasons: shear and tension Concrete is strong in compression, but weak in tension, when you apply a vertical downward force upon the footing from the wall/ column it holds up, the top level is in compression (pushed toward the middle) but the bottom is in tension (pulled from the middle); the steel exists to make up for the low tensile strength of concrete in those regions. Concrete also has mid level shear strength, not entirely weak, but simultaneously requiring some help from steel stirrups, which act as compressive steel when the footing is in shear. Another major reason is the variability in concrete strength that can occur depending on mix, aggregate, pour etc, whereas steel is generally known in its properties, low variability, it can make up for the weakness of concrete that can occur.
What is curing of concrete?
The curing of concrete is a reaction between the type of cement in the concrete and the water. This reaction between cement and water is known as hydration. When the concrete sets and gains strength through this process it is known as curing. Test cylinders of concrete for construction projects are placed in a curing room where they are continuous misted with water at 23 +-2 degrees Celsius for 7 and 28 days before testing. This provides adequate curing.
What is creep in concrete?
Creep is what happens when concrete changes form because of pressure or load on the concrete. It can occur immediately or long term.
How do you explain the who what when why how?
Who was involved, What happened, When did it occur, Why did it occur, and How did it happen.
The difference between setting and hardening in cement?
SettingSetting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture.HardeningHardening of the concrete is the stage when the mixture gains strength. The cement ingredient begins to attach itself to the aggregate as the water dries off the mixture. The hydration of water is what starts the hardening process. It generally takes five to seven days for the concrete to complete the hardening process. The easiest way to increase the strength of concrete is to add cement to the mixture. The more water used in the mixture, the weaker the concrete and it will also delay the hardening process. Once the concrete has hydrated all the water from the mixture, the hardening process is complete and the concrete is as strong as it will get.
How does the fineness affect the time of setting?
