WBS stands for Work Breakdown Structure, which is a hierarchical decomposition of the total scope of work to be carried out by the project team.

• WBS for a highway project would include major components like earthwork, pavement, drainage, signage, lighting, etc.

• WBS for a structure project would include components like foundation, superstructure, finishes, MEP (mechanical, electrical, plumbing), etc.

• Each major component i...read more

Silt content in concrete affects strength; allowable limits are crucial for durability and performance.

• Silt content should not exceed 5% by weight of the total aggregate.

• Excessive silt can lead to reduced workability and strength.

• For example, a concrete mix with 10% silt may experience significant strength loss.

• Silt can also increase water demand, affecting the water-cement ratio.

The mix design process in concrete technology involves selecting materials and proportions to achieve desired strength and durability.

• 1. Determine the purpose of the concrete (e.g., structural, decorative).

• 2. Select the appropriate materials: cement, aggregates, water, and additives.

• 3. Calculate the water-cement ratio based on strength requirements.

• 4. Conduct trial mixes to test workability and strength.

• 5. Adjust propo...read more
