Dressing Of Stones

Natural stone, must be extracted from their thick bed. After quarrying large chunks of rocks, it's vital to cut them into smaller pieces so that they can be used for building construction.

An area where exposed surfaces of high-quality natural rock are plentifully available is called "quarry," and the method of removing stones from the bed is referred to as "quarrying."

This can be done using hand tools such as a pickaxe and chisels. Or using machines. Blasting with explosives is another technique used to quarry.

The way stones are dressed is essential to ensure they can be dressed in appropriate shape and polished to give an even surface, if you want.

The stones are utilized in a variety of forms of masonry. Therefore, it needs to be cut and shaped in order to be suitable for the kind of work required.

Dressing Of Stones

In this post, we'll go over different types of and methods for covering stones to achieve the desired shape and surface.

Definition:

The Dressing of Stone is described by "The process of giving a proper size, shape and finish to the roughly broken stones as obtained from the quarry."

This is accomplished using hand tools such as an axe, chisels and so on. Or by using machines.

The process can be done either in a manual or mechanical manner. A polished stone is suitable to be used in a specific setting in a building.

Objectives:

Stones extracted from quarries are extremely imperfect and uneven in form and quite heavy in terms of weight and size.

Different goals of dressing are as follows:

(a) to reduce the size of large stones to ensure that they can be reduced to easily transportable pieces that can be easily lifted. This shrinking in size is usually done within the quarry because it saves transport expenses.

(b) to provide a suitable form to stone. It is known that stone are used in a variety of locations in the construction, e.g., in foundations, arches, walls, or as flooring. Each needing a specific form.

The information can be found at the quarry , and on the site of construction.

(c) For an attractive appearance. For residential construction stone is used not just for their additional durability, strength and endurance, but also due to their aesthetic worth.

It is possible to have stone floors beautiful and attractive in design, and can last for a lengthy period of time. A stone home has its distinctive character in an urban area of concrete structures.

Stages in the Dressing of Stone.

The various phases of dressing stones include:

1. Sizing:

It's the procedure of bringing the blocks that are irregular to the required dimensions by removing excess portions. This is accomplished with the aid of chisels and hand hammers.

2. Shaping:

This is the next step after sizing, and involves cutting off sharp projections. Numerous stones are employed in construction, after shaping.

3. Planing:

This is a rather modern method of dressing, whereby the stone is cleaned off all imperfections off the surface.

4. Finishing:

This can only be done in the cases of specially-dressed stones. This is a result of rubbing the stones' surface with abrasive material that is suitable, like silicon carbide.

5. Polishing:

This is the last step in dressing , and it is only performed on limestone, marbles and granite.

Finalization Procedure for all types of Dressed Stones

After the shaping of the stone is finished to the desired size and shape the stone is then completed by two stepstwo steps

1. Dragging or Combing

The stone that is dressed is processed by pulling the coarse drag backwards in a forward direction until marks of the tool are removed. This can be followed by a second drags and fine drags depending on the level of uniformity required.

2. Polishing

Stones that need to be polished should be accomplished by rubbing them using an appropriate abrasive and then wetting the surface and using water.

Alternately, polishing stones can be accomplished by putting them with a firm grip on the top of the table, to which an abrasive material, such as carborundum or sand are fed.

The final polishing is done by a rubber or felt making use of lime oxide, referred to by the trade name 'putty powder to polish the surface.
