Green Building – Sustainable Materials For Home Construction or Table Top Epoxy South Africa?
There are prominent issues in the contemporary society especially those that tackle the massive impact of things in the environment. In the real estate industry, preferring technologies and systems that cater to the preservation of the environment is becoming a trend. One of the concerns prevalent today is on the use of sustainable materials for home construction.
There are innumerable criteria you can actually consider when talking about sustainable materials and how such items are qualified under this category.
One of the main properties that sustainable and green buildings must be eligible with is its less environment impact. Table Top Epoxy South Africa in Top since such real property entities account for many effects on the use of land, water and energy consumption as well as the alteration in the air and the atmosphere, buildings must primarily reduce its consumption of natural resources which are slowly depleting and eliminated without chances of renewal.
Sustainable materials are the ones that are recycled and reused in order to build or renovate homes and buildings. This way, you are not contributing to the exhaustion of the natural resources in order to answer the demands for new materials and items to use for construction and renovation of your property. There are numerous industries in the world of real estate that cater to the notion of recycling and refurbishing materials instead of producing new ones for constructing new properties or improving old ones.
In general, bear in mind that the process of building construction is definitely producing a lot of wastes. Hence, the materials that are recycled and reused must have the ability to reincorporate whatever scraps or wastes are made and remixed or reused it for other building construction purposes.
Another important criterion to consider is to look into the sustainability features of the material and to know if it is truly sustainable from the very moment it was harvested or gained as a raw material up to the time of its eventual disposal.
The material must have very minimal impact to the environment especially in terms of the waste, emission, energy consumption and its capacity to replenish itself in order not to deplete the resources taken from nature due to its production. The energy consumption especially in terms of the harvesting process of the material, its actual processing and the transportation required are all considerable qualities to tag a material that is truly not hazardous to nature.
There are different types of resources which are not recyclable however are still considered sustainable because these primarily have the capacity to highly replenish. Examples of such materials are straw, hay, bamboo, cork, adobe and clay among others. They are tagged with this kind of quality because they can quickly replenish and renew their quantity after they have been harvested. These materials also have low or very minimal rates on emission and are highly deemed for energy conservation.
Hence, if you want to build an eco-friendly and healthier property, you must consider using all natural materials which are sustainable and renewable in nature in every corner and foundation of your home.

Building materials are those products which are used for the construction of homes and other buildings. There are many varieties of materials used for constructing houses. In some countries, materials are used according to the climatic conditions of the place.
Basically the building materials are classified into two types-the synthetic and natural materials. The synthetic materials are those which are man-made where as the natural materials are those which have been originated naturally.
Commonly Used Building Materials
Some of the most widely used materials for constructing homes and commercial buildings include:
Clay: One of the most widely used building materials includes clay as well as mud. Both these materials are used to build homes. It is considered the most suitable constructing material in warm places as it keeps the interiors cool. It also has the advantage of being long lasting though it is not as strong as the concrete buildings.
Glass: Another notable material used for constructing offices and huge mansions. Glass buildings are quiet common these days with a variety of glass available in the markets today. The diverse variety includes frosted glass, colored glass and stained glass.
Rock: Rock has been considered as the oldest building materials used for constructing homes. It is the strongest and most durable material used for construction. Though it was widely used in ancient times it is now rarely used due to many factors.
Metals: Metals are the considered one of the best materials that can be used these days. Most of the structures are built in metals like iron and steel to ensure strength and durability. Metal structures are strong, expensive and last for a long period of time.
Concrete: Concrete structures are also durable and strong. Made of gravel, sand, water and cement, concrete is used build homes and offices.
Wood: Wood is also used to build homes and offices since ages. There are many kinds of wood used as building materials. However, it is important to use good quality wood to ensure better durability. Low quality wood is susceptible to different kinds of extremities like termites, cracks and splinters.
Marbles and Granites: Other materials include marble, granite, ceramic tiles and so froth. Granite countertops are most preferred by people due to its beauty and versatility. Marbles are used for constructing houses as it is known for its unique features. Granite is also used for constructing walls and countertops because it lasts longer and is the strongest stone on earth apart from diamonds.
Other Essential Materials
In addition to the above mentioned materials, plastic is also widely used as building materials. Plastic pipes, tubes and so forth are essential for any home or office. In addition to the above, the use of brass materials is also common.
Most of these materials can be bought online from various manufacturers and suppliers at reasonable rates. The ever growing needs to build new homes, offices and the renovation of old buildings have lead to a substantial growth of the industry producing building materials.

Steel buildings are common all over the World. The usage of steel in construction is a not a new practice. However emerging technology changes the type of construction materials we use. This is also applicable to steel.
Earlier hot rolled sheets were in use, which were manufactured at elevated temperatures. This structural steel is rolled unto its shape while hot at a temperature of 1700 degree Fahrenheit. The hot rolled steel shows lesser degree of accuracy than the cold formed steel hence its use is increasing worldwide.
The cold processed steel comes with much more plus points than the hot rolled steel does. This steel sheets are processed at scalable temperature to form shapes of building sections as desired. This type of steel is easy to handle, light weight and is easy to use.
This type of steel is mostly used in prefabricated buildings. In such type of construction, steel sheets are used to make the desired section. These are than transported to the building site. Most important sections are steel roof, wall panel, wall studs and floor decks. In the manufacturing units cold roll forming or press breaking accords the desired shape to the sections.
For production of roof, floor and wall panels' cold roll forming is mostly used. This material is also employed for important structural components.
The cold process increases the strength of the section, hence it is preferred. The yield point and tensile strength depends upon the type of the steel used and also on the type of cold forming.
Cold formed steel prefabricated section finds use in multiple applications. The manufacture in factories and installations at the site is beneficial. This saves both the time and money. In building construction, the doors and windows are also made from this steel. In highway construction, the guard rail and barriers are manufactured using cold formed steel. Transportation does not pose much of a problem as the material is light weight.
The sections formed using the cold formed steel are often used for the entire building. The material is also used for making the roof, floor and wall systems. The material is also used for making framing members such as studs, joists and truss. The primary as well as secondary structures are also made of light gauge steel. The load bearing steel stud wall is a fine example of primary structure used in commercial and residential buildings.
Hence hospitals, hotels, education institutes, research institutions all prefer the prefab construction technique. In India government offices prefer steel construction to traditional building methods.
Resistance to fire, rot, fungi, algae etc are plus points of this material. The ability to gel with many types of paints and coatings also helps. Cold formed steel is strong, durable and ductile material.
This is a very synonymous trade with construction works, especially the construction of buildings. Most of the modern construction has its structural frame fabricated out of concrete. There are two main types of concrete:
· Mass Concrete: This is usually a 'weak' form of concrete. This means that it does not perform any load bearing duties. It is used in ground floor slabs, platforms or simple bases for light works.
· Structural (reinforced) concrete: This is used to carry loads and is therefore a common part of buildings and other structures like retaining walls. It is usually added strength properties by the use of steel (reinforcement). The specification of concrete is usually dependent on the amount of strength it is supposed to carry.
Concrete is made from a mixture of the following main parts;
· Ballast (Course aggregate): This forms the bulk of concrete parts. It is made from crushed stone and the size of the aggregates determines (partly) the strength and workability of concrete.
· Sand (fine aggregate): This is the second largest part of concrete. In concrete, it fills the gaps in between the course aggregates.
· Cement (binder): This binds together the other parts of concrete and hardens in a chemical process to form a strong mass, shaped to the desired form and size.
The three parts form the main type of concrete, which is usually given as ratio as in the following manner; (1:2:4 - One part Cement, Two parts Sand and Four parts Ballast). The three are mixed with clean water in a specified quantity. Cement reacts with water to form its strength.
Other constituents of concrete include;
· Reinforcement: Usually in the form of steel bars, but also in the form of fibrous material. Gives concrete enhanced strength properties.
· Additives: Chemical compounds added in concrete to give it enhanced characteristics like more flowability and water resistance.
Alongside this, concrete also needs moulds, commonly known as formwork, to give it support as well as shape it in the desired form, for example circular shape in columns. The conventional formwork was made of timber and poles, although this is quickly changing to other materials, mainly steel and aluminium.
Concrete works constitute the following works, which are either carried out by hand, by machine or a combination of both.
· Formwork construction: Depending on the material to be used, this can be purely a carpentry affair or a simple steel assembly. It also includes works like leveling and waterproofing. It also involves removal of formwork after a specified period, for example seven days, a process known as striking.
· Mixing: As earlier discussed. It is either done on site or mixed offsite and delivered in premix trucks.
· Steel Fixing: Where reinforced concrete to be set up, steel bars are usually fabricated and laid into the formwork before concrete is put. This involves works like bending, cutting and binding. This process is usually guided by an engineer's drawing. This is mostly a manual affair.
· Placing: This refers to the act of putting concrete into the formwork. It is in most cases done above the ground level and as such involves either hoisting or dropping. Hoisting is either done manually or mechanically using hoists or concrete pumps.
· Compacting: This is done to make sure that concrete forms a compact mass, thus enhancing its strength. In small scale projects, it is done by hand, but in large projects, it is either done using poker vibrators (hand held or otherwise) or by use of additives to achieve self-compacting concrete.
· Curing refers to the task of allowing proper chemical bonding of cement by hydration (watering). It is usually done for a specified period of time, for example thirty days.
