Lay the bricks on their bed with the frogs facing up.Courses should be truly horizontal and truly vertical joints.The use of bricks should be avoided as much as possible.Generally, the height of brick masonry is limited to 1.5 meters in a day.To ensure continuous bonding, the walls should be butted with a toothed end at…

In this type of ashlar masonry, the strip is provided as above. However, it is chamfered or beveled at an angle of 45 degrees by a chisel to a depth of about 25 mm. Another strip 12 mm wide is then provided on the remaining exposed face of the stone and the surface inside the…

In this case, the exposed faces of the facing stones between the chisel draftings all around are left undressed. However, the projections of sizes more than 8 cm are broken. All other specifications regarding the sizes of the stones and the bond are kept similar to that of ashlar rough tooled masonry .

Exposed faces of this type of masonry should be given a finely dressed chisel draft of about 25mm width. Between drafts, parts should be roughly tooled. Joint thickness should be 6 mm.

In all beds, joints and face stones should be well prepared so that they conform to the desired pattern. Stones placed in regular courses should not be less than 300mm in height. The width of the stones should not be less than the height of the course. Also, the length of the stones should be…

It is expensive, high grade and high quality masonry. It is made of precisely dressed stones with uniform and very fine joints of about 3 mm thickness. By arranging stone blocks in different patterns, a variety of appearances can be achieved. Ashlar masonry walls can be backed with ashlar or rubble masonry.

In this type of masonry, the stones used as flints are irregularly shaped nodules of silica. Width and thickness vary from 80 mm to 15 cm and length from 15 to 30 cm.

In this type of masonry, the stones are hammer dressed and the stones selected for face work are dressed into an irregular polygonal shape. Thus, the joints of the face seem to run in all directions in a random pattern. It should be noted that this type of construction requires more skill.

It is very similar in construction to rubble masonry set III except that no mortar is used in the joints. This type of construction is the cheapest, but requires more skill to build. It is widely used for pitching compound walls at bridge approaches, retaining walls, etc. To prevent the shifting of the stones and…

In Stones of irregular sizes and shapes are used in this type of rubble masonry. The stones are arranged to give a good shape. It should be noted that making masonry structurally sound requires more skill. If the face stones are chisel dressed and the mortar joints are not more than 6 mm thick, it…
