Q4. What is bleeding in concrete?
Ans. 
Bleeding in concrete is the upward movement of water in a freshly placed concrete mix due to the settlement of solid particles.
• Bleeding occurs when water in the mix rises to the surface of the concrete.

• It is more common in high workability mixes with a high water-cement ratio.

• Bleeding can lead to segregation of the mix if not properly managed.

• To reduce bleeding, proper mix design and consolidation techniques should be ...read more

Q5. Whate is rainforced cement concrete?
Ans. 
Reinforced cement concrete is a composite material made of cement, water, aggregates, and steel reinforcement bars.
• It is a combination of concrete and steel bars to enhance the strength and durability of the structure.

• The steel bars are placed in the concrete in such a way that they work together to resist tensile forces.

• Reinforced cement concrete is commonly used in construction of buildings, bridges, dams, and other ...read more

Q1. How many types of foundation and describe it.
Ans. 
There are mainly four types of foundations: shallow, deep, pile, and raft.
• Shallow foundations are used when the soil is strong enough to support the structure's weight close to the surface.

• Deep foundations are used when the soil is weak and the structure needs to be supported at a greater depth.

• Pile foundations involve driving piles into the ground to support the structure.

• Raft foundations are large slabs that support ...read more
