Q: The cement used for grouting operations in large structure is:
  • A. Quick Setting Cement
  • B. Low Heat Cement
  • C. Portland Pozzolana Cement
  • D. Super Sulphated Cement
Correct Answer: Option A - Grouting– Grouting is a process of filling the cracks or voids under pressure in concrete or masonry structural member to change its physical characteristics. • Grout is a flowable plastic material with negligible shrinkage to fill the voids completely. • Application of quick setting cement. – Grouting – Under water concreting • Where plugging effect is desired, accelerators are used where grout is to be pumped, retarders are used.
