Q1. What is the process of using admixture in concrete
Ans. 
Admixtures are added to concrete to alter its properties or enhance its performance.
• Admixtures are added to concrete during mixing to modify its properties such as workability, strength, durability, and setting time.

• They can be classified into different types such as water-reducing, air-entraining, accelerating, retarding, and plasticizers.

• Examples of admixtures include superplasticizers, which improve workability with...read more

Q2. What is the proportionate of m15 pcc
Ans. 
The proportionate of M15 PCC is 1:2:4 (cement:sand:aggregate).
• M15 PCC stands for Mix 15 Plain Cement Concrete.

• The proportionate of M15 PCC is 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts aggregate.

• This proportion is commonly used in construction for moderate strength concrete.

Q3. What is liquid limit and plastic limit
Ans. 
Liquid limit and plastic limit are two important properties of soil used in geotechnical engineering.
• Liquid limit is the moisture content at which soil changes from a plastic to a liquid state.

• Plastic limit is the moisture content at which soil changes from a plastic to a semi-solid state.

• The difference between liquid limit and plastic limit is known as the plasticity index.

• These properties are determined using standar...read more
