Q1. What's BBS full form? And how to find weight of bar.
Ans. 
BBS stands for Bar Bending Schedule. Weight of a bar can be calculated using the formula: Weight = (D^2/162) * L, where D is diameter of bar in mm and L is length of bar in meters.

Q2. What's self compacting concrete?
Ans. 
Self compacting concrete is a type of concrete that does not require vibration or compaction during placement.
• Contains high flowability and segregation resistance

• Achieves full compaction purely through its own weight and without the need for mechanical vibration

• Ideal for complex structures with congested reinforcement or in areas with limited access

• Reduces labor costs and construction time

• Examples include SCC mixtures ...read more

Q3. What's different between nominal mix and design mix?
Ans. 
Nominal mix is a pre-defined mix ratio while design mix is a mix ratio calculated based on specific requirements.
• Nominal mix uses pre-determined ratios like 1:2:4 for concrete, while design mix is calculated based on specific requirements like strength and durability.

• Design mix involves testing of materials to determine the optimal mix ratio, while nominal mix does not require such testing.

• Design mix is more precise an...read more

Q4. What's w/c ratio? Explain me.
Ans. 
w/c ratio stands for water-cement ratio, it is the ratio of the weight of water to the weight of cement used in a concrete mix.
• w/c ratio is a crucial factor in determining the strength and durability of concrete.

• A lower w/c ratio indicates a stronger and more durable concrete mix.

• The w/c ratio should be carefully controlled to achieve the desired concrete properties.

• For example, a w/c ratio of 0.5 means that for every

Q1. What is hydration process during casting of concrete?
Ans. 
Hydration process is the chemical reaction between cement and water which results in the hardening of concrete.
• Hydration process starts as soon as water is added to cement.

• The reaction produces heat and causes the mixture to harden and gain strength.

• The process continues for weeks and even months, resulting in a stronger and more durable concrete.

• The amount of water used in the mixture affects the hydration process and...read more

Q3. Why used send in concrete mixer
Ans. 
Water is added to concrete mixer to make the mixture more workable and to achieve the desired consistency.
• Water is added to hydrate the cement and activate the chemical reaction that causes it to harden

• The amount of water added affects the strength and durability of the concrete

• Too much water can weaken the concrete and cause cracking

• The water should be added gradually and mixed thoroughly to ensure even distribution
