Which types of chemicals and admixtures used in the construction industry for normal conditions as well as seismic conditions? How we use the chemicals in building construction? When we required the chemicals for building construction?

Period of building and its relation with frequency:
Natural period:
- The natural period of a building is simply a time taken by it to undergo one complete cycle of oscillation.
- The natural period is one of the properties or building which is controlled by mass and stiffness.
- Formula to find out natural period is,
Tn =2π√(m/k) where,
- Tn is a natural period of building.
- m is mass
- k is stiffness
Reciprocal of the natural period of a building is nothing but the natural frequency and its unit is Hertz(Hz)
