Green Building – Sustainable Materials For Home Construction or Construction And Building Materials?
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. Construction And Building Materials in Pretoria 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.

The exhibition stand is changing. In the past, exhibitors used heavy materials to set up an exhibition booth that was cumbersome to build and to move. Today, the focus on the use of lightweight materials, and in particular fabric, means that the exhibition stand is lightweight and less expensive.
Current trends in the exhibition stand design worldwide include an increased use of various materials such as fabric, an emphasis on lighting, creating a "box" design, building organic shapes, and using bold colours.
Fabric is the material most used in exhibit stands in current trends. Because fabric is light weight, and can be moulded to create eye catching shapes, it is the material of choice for the modern exhibitor. Fabric can be used as an accent or to construct an entire booth. The latest trend with fabric is the use of translucent fabric to display full wall graphics. Fabric can define the space as the part of the branding for the exhibition stand, while maintaining the open, airy feeling of space, so that attendees do not feel enclosed within the exhibit.
Wood is the next most common material to use, with metal the preferred finish for some industries, particularly health care, kitchen, bath, and the retail industries. Metal is difficult to damage and is therefore cost effective for use in long-term exhibits or exhibition stands that will be transported across the country to show in the various capital cities.
Ten years ago, many exhibitors simply used the available lighting within the exhibition centre. Now, it is virtually impossible to spot an exhibition stand that does not include separate lighting to accentuate or highlight products. Exhibition lighting has become an integral part of excellent stand design.
From halogens to gobos, from wash lights to spot lights, you can use lights in your exhibition stand design to create a mood, highlight particular products, and to create special effects that attract attention to your exhibition. Use lights to set your booth apart from the competition.
Exhibitor Magazine has annual design awards and at least 75 per cent of the winners this year have used a "box design". Although the box can be rectangular, oval, round, or whatever shape you like, the box itself is an exhibit that contains and delineates the space itself. Rather than use a traditional exhibition booth, and simply build the exhibit into the space remaining from the walls of the booth, the box design allows an exhibit to use the entire space allocated to the stand and to define the space without the use of booth walls. If your branding uses an oval shape, create an oval shaped exhibition stand within the space allocated, instead of using the traditional rectangle booth.
The use of new shapes is a trend that stems from the use of computer generated designs in exhibition stands. Curves, tombstone shapes, wave shapes, and other complex shapes are being used to add interest and movement to exhibition stands.
Graphics are also using shapes as part of the design. Graphics are now focusing on a single message and are becoming a large part of the exhibition stand. The latest worldwide trend in graphics is to take advantage of the new printing processes and turn walls into a full graphic that attracts attention. Designers are using shapes, such as ovals, to show the difference between the graphic and the wall.
Colours are definitely one of the trends that continually changes within the exhibition industry. One year aqua is all the rage and the next magenta red is the accent colour of choice. Using trendy colours can lead to additional expense when you have to change the colour scheme to meet the latest trend, or your stand will be seen as out of date. The latest colour trend is to mix conservative colours, such as black, gray, and tan, with vibrant colour accents. However, some exhibitors have experienced success by using aggressive colours for the entire stand, such as yellow, green, or orange. Using colour in lighting is also a popular trend.
The main trends in exhibition stand design are the use of fabric, lights, shapes, and colours to define the space in new and different ways that attract attention. If you want to have a trendy exhibition stand, pay attention to the design of the shape of your exhibition stand, and think outside the traditional "booth" approach.

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.

Cement, bricks and tiles are the main building materials used in the construction of buildings. Today, increase in the demand for various building materials have led to many building material manufacturing companies. Many new building materials are environmental hazards, which have become a big concern to all.
Traditionally, the basic types of building materials used for construction were mud, stone and brush. Mud was used for filling the spaces between bricks and acted as a concrete and insulation. Centuries ago, houses were made entirely of dirt and clay. This was followed by the use of rocks (mainly granite) as building material. From the Neolithic period through the medieval age to modern times, granite has been commonly used as a building material. Brush structures were commonly seen in tropical areas and were made entirely from plant parts such as branches, bark, twigs and leaves. These structures were often used by Native Americans as resting places.
Stones and bricks were also common in construction. Different types of bricks have been and are still used for masonry. This includes specially shaped bricks for joints, striking and tooling, as well as glazed or rubbed bricks for decorative purposes.
Thatch is one of the oldest types of building material used for roofing. Another generic building material is wood. Because of the diverse character of different types of wood, it can be used for any type of structure in most climates. Even though wood structures were very common in earlier times, they disappeared with the approach of concrete structures.
Concrete is a composite building material comprised of aggregate and a binder (cement). Concrete finds good use in all types of building construction. Fly ash is a major ingredient in the concrete mix because of its lightweight and high thermal insulation.
More recently, new types of building materials are being used. These include metals (for the structural framework of larger buildings), plastics, asbestos and fabrics. Tar-based waterproof materials, paper linoleum, polyvinyl chloride clay and solvent coatings for inner wall are other building materials.
