The Background of Limestone and Its Various Uses

Fri, 02 Dec 2011 03:42:00 +0000

Limestone is a type of rock that is formed from the various amount of clay, sand flint and calcite. The calcite generally originates from marine organism and are also present in ground-water that precipitates the material. Limestone therefore is made up of 10% of the total volume of sedimentary rock all over the world.

Limestone is hypersensitive to erosion and there are a lot of eroded land forms such as pot holes ,caves and gorges that comprise a limestone. Limestone therefore are more resistant than any other sedimentary rocks and it is usually found among hills and down lands and typically among clay soils.

This kind of stone can form prominent outcrops by the earth's artefacts and islands. One example of limestone formation can be seen at Clare in Ireland. Limestone rocks are also dominant in Sweden, United States and Australia.

Limestone is also very popular in the realm of architecture as many building manufacturers use limestone for the fact that this type of stone is durable compared to other building materials that are available today. is readily obtainable and relatively easy to cut into blocks and are also good for a more complicated carving. This stone is  long-lasting and can stand up well to any exposure.

In fact, a cement is produced by roasting a powdered limestone added with a powdered clay in a rotary kiln. When the cement is combined with water, sand and crushed rock, a  chemical reaction will then produce a hard stone-like building material that is called concrete.

Limestone is further used as a frontage for most skyscrapers in a way of thin plates for covering than using solid blocks. Bruhn Limestone is the source of high-class quarried limestone that is recognised in Australia.

Pure limestone appear to be more or less white in colour. This is due to its impurities such as clay, organic remains, sand and few other materials that contribute and affect  its colour. Much novel limestone come in various colours, particularly on a weathered surface. Limestone might be crystalline, clastic, granular or hug or one in all depending on its class.

How to Apply Bruhn Rockseal Sealant on Limestone

Fri, 02 Sep 2011 11:52:00 +0000

Limestone is defined as a sedimentary rock that composes largely of the mineral calcite and aragonite. It is also composed of grains made from skeletal fragments of marine organism such as coral and foraminifera.

Limestone is very common in architecture and widely used in the UK and America. Across the world, Landmarks such as the Great Pyramids of Egypt  and its associate complexes are made of limestone. Tracing back the human history,  limestone has been already used in building monuments, houses and other structures.

Today, limestone has been more popularly used in building houses and commercial establishments. Because of the growing demand of this material in the construction industry, many limestone manufacturers are producing limestone in various types and colours to suit consumers unique preference.

Though limestone is a natural stone, when used as a construction material it needs protection against other elements to retain its durability over the years. That is because it can easily absorb moisture which can cause discolouration and its dirty appearance.

To avoid this, a seal must be applied over the stone’s surface. One of the most trusted limestone seal today is the Bruhn Rockseal which aims to protect natural limestone by coating the stone’s surface and converting it from soft material to a hard wearing water repellent finish.

The Bruhn Rockseal coating penetrates deep into the pores of the limestone and strengthen it so that the treated surface will not dust thus highlighting  the natural colour of the stone. The seal also prevent fungal growth and allow the stone to age naturally. The seal is also resistant to  airborne pollutants,  ultra-violet rays.

To apply the Bruhn Rockseal, follow the following procedures:

  • The sealant is supplied in 205 litre drums and it must be stirred thoroughly before application.
  • The limestone must be power washed with a low pressure fan spray to clean its pores before applying the sealant. Allow stone to touch dry before applying the sealant.
  • The stone should not be washed or sealed until the mortar has hardened sufficiently.
  • Ensure site is free from dust during washing and sealing.
  • Sealant must be applied in one heavy coat only. Do not double coat as this causes run marks.
  • Allow at least 24 hours for the sealant to dry. Allow two months for product to cure.
  • Wash out hose lines with clean water after use.

Uses of Limestone In Today's Building projects

Fri, 26 Aug 2011 13:04:00 +0000

Limestone is a sedimentary rock that is composed largely of minerals such as calcite and aragonite. Most limestone contains a variable amount of silica in form of chert or what they call as siliceous skeletal fragments.

The formation of limestone from the variety of flint, clay, sand and calcite has made it a very strong candidate for building structures and sculptures. Since the ancient times, the use of this material in architectural purpose and construction has widen. Limestone now has been the preferred masonry product over bricks by many builders for their building projects.

The variety of colours prevailing in limestone are derived from the impurities that are present in it. These can be clay, organic remains, sand and iron oxide. The formations of limestone can be crystalline, granular, elastic or massive and can be sorted more exactly as either Folk and Dunham. Limestone colour then enhance the beauty of the constructed building.

Limestone is used in architecture all over the world such as in modern construction in Europe and in other older landmarks including the great pyramids in Egypt. Builders use limestone because it is relatively easy to work with and is commonly available.

In today's modern time, limestone has become a top choice masonry material in building structures including houses and commercial establishments. It is commonly used because it is durable and can stand the test of time. Limestone is hypersensitive to erosion and a lot of eroded landforms like pot holes and caves contain limestone. Therefore, limestone holds soils and prevents erosion.

Limestone is also an ideal choice for flooring and blocks because of its simple structure. It consists of subtle patterning and comes in plate with neutral colours which made it appealing. These features make this stone a good choice compared to bricks or other masonry products. This is also best used for walls to. And because limestone come in many options, you can find the rock that will suit to each of your various building projects.

Furthermore, Limestone provides low maintenance in keeping its natural beauty. It is widely quarried for roadbed, cement and landscape construction by many limestone manufacturer around the world.
