Which of the following types of glass fibre is most commonly used for reinforcement in construction? 

Explanation:

E-glass (Electrical glass)

• It is the most commonly used type of glass fibre for reinforcement in construction. It is made from silica (sand) and alumina and has excellent electrical insulating properties, as well as good mechanical strength.
• E-glass is commonly used in composite materials for concrete reinforcement, as it provides a balance of cost, strength, and durability.

Categorization of Glasses

1. E - Glass (Electrical Glass):

   • Most commonly used for construction reinforcement.

   • Offers good mechanical strength, electrical insulation, and durability.

   • Widely used in composite materials and concrete reinforcement.

2. A - Glass (Alkaline Glass):

   • Primarily used in glass containers and bottles.

   • Susceptible to alkaline conditions, making it less suitable for construction.

3. S - Glass (Strength Glass):

   • High tensile strength, ideal for aerospace and military applications.

   • Expensive and not typically used in general construction.

4. C - Glass (Chemical Glass):

   • Resistant to chemicals, used in chemical-resistant glass products.

   • Not commonly used in construction due to its specialized nature.
