What is Dressing of Stone? Types of Stone Dressing Process

What is Dressing of Stone?

Stone is a construction material that is used in buildings as well as road and railway construction. Stone of different shapes and sizes are required for different jobs. The stones quarried from quarries cannot be used directly for construction work as they are quite irregular. This is why they need to be cut or dressed to the required size and shape before use. The dressing of stone is a process by which quarried stones are properly cut and dressed, ultimately giving a shape to a particular work.

Different Types of Stone Dressing Process

In this article, you can learn about several types of stone dressing processes that are commonly implemented.

1. Quarry-Faced Finish

Some of the stone blocks are directly used in stone masonry work without any dressing at the site of the work. But, the large projection of the stone faces is knocked off by using a quarry hammer as soon as the stone is quarried. The faces of such types of stones are rough. These types of stones are called self-faced or quarry-faced stones.

2. Scabbling Finish

It is also a type of rough dressing of stone. In this type of finish, the irregular projections from the quarried stone blocks are removed by means of a scabbling hammer. Scabbling Finish helps to improve the aesthetic value of the stone.

3. Axed Finish

In this type of finish, mostly the hard stone surfaces are dressed with the help of an Axe. This is also a sort of rough dressing of stones.

4. Tooled Finish

In this type of dressing, the surface of the stone is dressed with the help of different tools such as chisels, drag, etc. In this finish, continuous parallel marks by the chisel, either horizontal or verticle or inclined, are left on the surface of the stones. By using different chisels, different patterns of finished surfaces can be obtained.

5. Punched Finish

In this type of stone dressing, the exposed surface of the stone is dressed by using punches. The entire surface consists of uniformly distributed punch marks. This is also a rough dressing process. And, that is why it is required further dressing before using it.

6. Furrowed Finish

In this type of stone dressing, the exposed face of the stone is finished by making a number of vertical and horizontal grooves. Typically, the grooves that form on the surface of the stone are about 10 mm wide. And, a 2 cm wide margin is also made around the edges of the exposed face.

How to Clean Your House Fast? House Cleaning Tips & Tricks

Fast House Cleaning Tips

Everyone likes clean houses but does not like to clean houses. A clean house gives freshness to the occupants. Is it really possible to clean the house fast? Yes, here I will share with you some tips and tricks that will help you to clean your house quickly.

Important Points During Cleaning

The fan must be switched off while cleaning. The windows and doors of the house should be kept open. Hand gloves should be used. And a dustproof max also needs to be wear.

Best Time for House Cleaning

The best time to clean the house is before taking bath. After cleaning everything, you need to clean yourself too. Therefore, before bathing is the right time to start cleaning your house. But, if you are ready to take a bath at any time, there is no set time to start cleaning your house.

Starting and Finishing Point of Cleaning

It is a very important point and must consider before starting to clean randomly. Cleaning work should be started from the rooms of a house and should end in the bathroom. Starting should be done from top to bottom. Because top dust can drop at bottom of the room. And also, always start from the point where dust is maximum.

Room Cleaning Tips

As I said before, cleaning should be started at the point where dust will be maximum. Must use a vacuum cleaner, which helps to remove maximum dust in a minimum time. Use dry cloth and gel to clean the mirror or glass panel of the room. For cleaning the table or any desk, first, you need to move all the things which are on the table or desk, then start cleaning by using a vacuum cleaner or by using a dry cloth. And also clean all the things that were on the table before placing them again on the table. Read Also: Standard Room Sizes.

Kitchen Cleaning Tips

Starting from the rack first, remove the dust from the rack and other places where there is dust. Then start cleaning things that require water to clean them and finally clean the kitchen basin and sink.

Bathroom Cleaning Tips

In the case of a bathroom, starting from the bathtub and ending on the bath floor. Before you start cleaning the bathtub you first need to partially fill it with water. After that, clean the sides of the bathtub and then release the water and clean the bottom of the bathtub. Then start cleaning the toilet with the help of gel. And finally, clean the floor of the bathroom.

Don’t forget to Routinely Wash your Cleaning Tools

After completing the cleaning work, clean all the cleaning tools. It will help you to do your next job without interruption.

Frequent Cleaning

For example; If you clean your house 1 day in a week, then I would recommend you do this 2 days in a week. Because in a short interval cleaning work consumes less time than long-interval cleaning.

Compound Interest Mathematical Problem & Solution

Compound Interest Mathematical Problem

Question: A Person has invested Rs. 10000 in a bank at an interest of 10% per annum. How much amount will receive After 2 years if the compounding is done?

a) Annually.
b) Semi-Annually.
c)Quarterly.
d)Monthly.
e)Daily

Answer:

FV_n = PV ( 1+ ^r/_m )^mn

Where, FVn = Future value after n years

n = Number of years [In the above math, n = 2]

m = Number of times compounding is done in a year

a) Annually.

Here, r = 0.10 (10%), m = 1.

FV = PV ( 1+ ^0.10/₁ )^1×2 = 10000(1+0.10)²= 10000 × (1.10)² = 12100 Rs.

b) Semi-Annually.

Here, r = 0.10 (10%), m = 2.

FV = PV ( 1+ ^0.10/₂ )^2×2 = 10000(1+0.05)⁴= 10000 × (1.05)⁴ = 12155 Rs.

c) Quarterly.

Here, r = 0.10 (10%), m = 4.

FV = PV ( 1+ ^0.10/₄ )^4×2 = 10000(1+0.025)⁸= 10000 × (1.025)⁸ = 12184 Rs.

d) Monthly.

Here, r = 0.10 (10%), m = 12.

FV = PV ( 1+ ^0.10/₁₂)^12×2 = 10000(1+0.0083)²⁴= 10000 × (1.0083)²⁴ = 12194 Rs.

e) Daily

Here, r = 0.10 (10%), m = 365.

FV = PV ( 1+ ^0.10/₃₆₅ )^365×2 = 10000(1+0.000274)⁷³⁰= 10000 × (1.000274)⁷³⁰ = 12214 Rs.
