Q1. On slag reactivity and it's effect on cement performance
Ans. 
Slag reactivity can impact cement performance by influencing hydration reactions and strength development.
• Slag reactivity refers to the ability of slag to react with water and form cementitious compounds.

• Higher slag reactivity can lead to faster hydration reactions and improved early strength development.

• However, excessive slag reactivity can also result in rapid setting and reduced workability of the concrete.

• Proper s...read more

Q4. Limitations of laws of thermodynamic
Ans. 
Limitations of laws of thermodynamics
• The laws of thermodynamics are based on idealized systems and may not fully apply to real-world situations

• They do not account for quantum effects at very small scales

• The laws assume equilibrium conditions, which may not always be the case in practical scenarios

• They do not consider the effects of external factors such as friction, air resistance, or electrical resistance

• The laws do n...read more
