Q: Cement mortar of fluid consistency used to fill the voids and joints in masonry and to repair the cracks is known as:
  • A. Guniting and permeability
  • B. Guniting
  • C. Grout
  • D. Permeability
Correct Answer: Option C - Grout– Fluid consistency of cement mortar used to fill the voids and joints in masonry and to repair the cracks is called as Grout. It is also used to increase the bearing capacity of soil by injection, Grouts finds extensive use in dams to fill the cracks. Guniting– Application of mortar or concrete under pneumatic pressure through a cement gun is known as guniting. It is generally used for construction of thin section like as lining of tunnels, swimming pools, repairing of deteriorated concrete damaged by fire. • Thickness of gunite should not be less than 40 mm for repairing structures.
