MASONRY CONSTRUCTION

5. 5 Stone Masonry Construction • The construction of stones bonded together with mortar is termed as stone masonry where the stones are available in a abundance in nature, on cutting and dressing to the proper shape, they provide an economical material for the construction of various building components such as walls, columns, footings.

§ Drove Chisel is a tool used by stonemasons for smoothing off roughly finished stones. . The drove chisel is used for softer rocks such as limestone and marble, while harder rock such as granite requires a pointtoothed chisel.

5. 6 Grouting Masonry

Low-lift Method and High-lift Method of Grouting • Low- and high-lift grouting are both traditional grouting methods, with the difference being the height of lift.

5. 7 Protections 5. 7. 1 Bracing High-lift grouting requires that walls be temporarily braced until the mortar and grout has fully set. Partially completed walls should also be braced during construction against lateral loads from wind or other forces applied before permanent supporting construction is completed. 5. 7. 2 Coverings Masonry walls should be covered at the end of each day and when work is not in progress. Excess moisture entering the wall during construction cause saturation of units, which may take weeks or months to dry out. Covers such as water-repellent tarps or heavy plastic sheets should extend a minimum of two feet down each side of uncompleted walls and be held securely in place. During construction, scaffold planks should also be turned on edge at the end of each day so that rain will not splash mortar droppings or dirt onto the face of the masonry.
