Top 8 Interview Q n A about Self Compacting #Concrete (SCC) as per IS 10262 : 2019

Q1. Name the Plasticizers used for Self Compacting #Concrete?

Answer: As per IS 10262: 2019 Clause-8.3 (c), Poly Carboxylate Ethers (PCE) is an admixture that is used as Plasticizers (Water reducing admixture) to reduce water in Self Compacting Concrete (SCC).

Q2. How much water reduction is possible with Polu Carboxylate Ethers (PCE)?

Answer: As per IS 10262: 2019 Clause-8.3 (c), Use of high range water reducing admixture like polycarboxylate ether-based high range water reducing admixture (water reduction > 30 percent) and sometimes also using a viscosity modifying admixture (VMA) in appropriate dosages.

Q3. What is the desirable size of Fines for Self Compacting #Concrete?

Answer: As per IS 10262: 2019 Clause-8.3 (a), the desirable size of Fines for Self Compacting Concrete is 0.125 mm or 125 Micron.

Q4. What is the amount of Fines preferable for Self Compacting #Concrete?

Answer: As per IS 10262: 2019 Clause-8.3 (a), Sufficient amount of fines (< 0.125 mm) preferably in the range of 400 kg/m3 to 600 kg/m3, inclusive of suitable quantities of fine aggregate and mineral admixtures like fly ash in suitable proportions, may be used for flowability while ensuring compliance with engineering properties particularly shrinkage.

Q5. What is the Maximum and Minimum limitation of water for Self Compacting Concrete?

Answer: As per IS 10262: 2019 Clause-8.3 (b), the Maximum and Minimum limitation of water for Self Compacting Concrete is from 150 to 210 kg/m³

Q6. What are the main features of Fresh Self Compacting# Concrete?

Answer: As per IS 10262: 2019 Clause-7.2, A concrete mix can only be classified as self-compacting concrete, if the requirements for all below-mentioned characteristics are fulfilled:

a) Filling ability (Flowability),

b) Passing ability,

c) Segregation resistance, and

d) Viscosity

The above tests shall be carried out as per IS 1199 (Part 6).

Q7. What is the limitation of height difference for the pouring of Concrete for the RCC column?

Answer: The limitation of the height difference for the pouring of #Concrete for the RCC column is 500 mm.

Q8. What is the Coarse aggregate size preferable for Self Compacting Concrete?

Answer: The Coarse aggregate size preferable for Self Compacting Concrete is 10 mm to 12mm.
