Natural Seasoning and Artificial Seasoning of Timber

Differences between Natural Seasoning and Artificial Seasoning

Natural Seasoning 

• It is difficult to reduce the moisture content below 15–18%
• It is simple and economical.
• It is more liable to attack of insects and fungi.
• It requires more space for stacking.
• It is a slow process.
• It gives stronger timber.

Artificial Seasoning

• The moisture content can be reduced to any desired level.
• It gives weaker timber.
• It is a quick process.
• It requires less space for stacking.
• It is less liable to attack of fungi.
• It is expensive and highly technical.

Advantages of Seasoning of timber - Building Material

 Seasoning of Timer MCQ

 following  statements are true or false:

        Seasoning of timber results in:

• 1 Increased strength

• 2. Increased durability

• 3. Reduced resilience

           

all of correct :
Three most important advantages of seasoning have already been made apparent:
1. Seasoned timber lasts much longer than unseasoned. i.e. durability Since the decay of timber is due to the attacks of wood-destroying fungi, and since the most important condition of the growth of these fungi is water, anything which lessens the amount of water in wood aids in its preservation.
2. Seasoning increases the strength of the timber.
3. In the case of treated timber, seasoning before treatment greatly increases the effectiveness of the ordinary methods of treatment, and seasoning after treatment prevents the rapid leaching out of the salts introduced to preserve the timber.
4. The saving in freight where timber is shipped from one place to another.
5. The resilience which the ability to store the stress-energy per unit volume reduces after seasoning.
