Masonry Working Manual:
Mixture of mortar: The blocks shall be embedded with a mortar, the strength of which is relatively lower than that of the mix used for making blocks in order to avoid the formation of cracks. A 1:6 Cement-Sand mortar may be used. (Refer IS: 6041-1985)
Wetting of Blocks: These blocks need not be wetted before or during the laying in the walls, in case the climate condition is required, the top & the sides of the blocks may be slightly moistened. (Refer IS: 6041-1985)
Provision of Lintels: Lintels for doors, windows and other openings shall be made of either RCC cast in situ or precast units, where openings occur close to one another, continuous lintels may be provided. The minimum reinforcement of 2-8 mm diameter mild steel bars shall be provided. The reinforcement shall be embedded in horizontal joints at interval of 900 to 1200 mm depending upon panel length, L. (Refer IS: 6041-1985)
Vertical Stiffeners shall be provided in the similar way for wall length more than 3 m.
Mortar Thickness: Keep it-limited to 10 mm in cement-sand mortar & 3-5mm in ready mix mortar.
(ReferIS: 6041-1985)
Plaster: Plaster thickness required, Internal: 8-10mm, External: 10-12mm with waterproofing. (Refer IS: 6041-1985)
Electric & Sanitary Chases: Chases to be grooved before plaster of wall and use electric wall chasing machine for zero vibration & good quality work. Do not chase on joints.
Beam & Column: Use wire mesh/fiber mesh for RCC- Masonry joints & bands.
