What is hydration of concrete?
i do not know, you consider median.
What is meaning of hydration?
Hydration means that u are hydrated, in other words, it's like drinking water or liquid
What is hydration and why is it important?
hydration is when you drink liquid and it keeps your system hydrated.
How do you draw hydration?
Draw someone with diabetes because a symptom of diabetes is having an unquenchable thirst thus meaning anyone with diabetes must be well hydrated.
What is the balanced equation of the hydration of CuSO4?
A hydration equation gives information regarding the reactants and products formed when a substance dissolves in water. Since a hydration reaction takes place in water, the solvent water can be indicated above the arrow. For example, the hydration equation for a strong electrolyte, such as , can also be written as Similarly, the hydration equation for a weak electrolyte, such as , and a nonelectrolyte, such as , can be written as

What is the effect of hydration on strength of a concrete?
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
How to prevent flash set OF CONCRETE?
You can add citric acid and sugar to stop hydration. But then the concrete is unusable and you need to throw it away.
What is the allowable maximum heat of hydration of concrete?
heat of hydration should not be more than66 cal/g and 75cal/g for 7&28 days respectively
What are the Advantages of curing the concrete?
Advantages of curing:Gains strengthYields microcracksReleases high heat of hydration.
What is the meaning of C10 concrete?

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 are the components of concrete?
cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
Why you add the water in the curing time is this water can used in the hydration or only for keep the water inside the concrete to not go outside?
Both
What is the effect of compaction and curing on the durability of concrete?
proper compaction and proper curing of the concrete gives good concrete. for compaction, it lessen the air voids or micro space between the aggregates of the concrete, those voids are very little which is not really visible. for curing, it lessen the heat of hydration of the cement.
What is the purpose of adding a curing compound to the concrete?
Curing is necessary for freshly cast concrete in order to maintain the moisture as the chemical constituents in cement react with water and heat evolves continuously until the setting process completes. The heat evolved during the setting of concrete is called heat of hydration, and this heat causes the water to evaporate. Proper and complete setting process is the most important phenomenon that imparts the desired strength to the concrete. If the freshly cast concrete is not cured, it develops cracks and also the chemical reactions will cease resulting in bad concrete.
