Concrete has been used as a decking material for decades. There are finishes achieved in concrete that give a good deck surface.
For example, salt finish concrete is commonly used and seen on many sidewalks. The surface of deck of the deck is non-slippery. Salt finish concrete can also be used with different colours.
A different type of look is achieved on the concrete by adding acid stains.
Also, there are chemicals available in the market that are added in the concrete mix which helps in keeping the deck cool.
Masonry decks have also been used for decades. Flagstone or travertine can be used as decking materials. The material and labour cost is more in these types of decks.
Tropical Pool Deck tiles
The pool deck tiles that are made of tropical wood are gaining popularity these days. They are assembled on a plastic base having high density. There are ways in which the pool deck tiles can be used. They could be:
- Staggered joints
- Aligned joints
As a measure to resist termites and moisture, the pool deck tiles are coated with non-toxic chemical coatings. It makes the surface of the deck safer to walk by reducing the chances of slipping.
Use of tropical wood makes the deck tiles more convenient because the surface temperature of the deck tiles remains regulated. Be it too cold or hot, it feels comfortable to walk on them.
Sinking Foundation | Building Construction
Foundation is the most primary component of the building on which it stands. The life of the building depends on the quality of foundation. For a good and stable foundation, the structural design of the foundation has to be done properly in a systematic way under the guidance of a structural engineer.
If the casting of foundation is not paid attention to and is not laid properly on a stable soil, the structural problems are bound to develop. Every soil has a specific bearing capacity which is very necessary to be checked before designing the foundation. Without the consideration of bearing capacity of soil, the structural design for the foundation may not be suitable for that land.
Cause of Sinking Foundation
Sinking foundation is a problem that occurs in case of improperly laid foundations which is the result of careless consideration of the soil type. The problems are very crucial and have to be solved as soon as they are detected in order to prevent the structure from further damage.
Detecting Foundation problems
People living in areas with unstable soil conditions need to watch out for the signs of foundation problems. Some of the signs could be as follows:
The house is gradually slanting to one side. (This is a very prominent example of sinking foundation problem. As soon as you notice this happening, you can immediately conclude it to be related to foundation and take action immediately before the condition of the structure gets worse.)
Fly ash Bricks | An alternative Building Material
Fly ash bricks are masonry units that are used in the construction of buildings. They are considered to be a part of good and affordable building materials. They contain Class C fly ash and water.
Fly ash bricks are made by compressing Class C fly ash and water at 4000psi and then curing is carried on for 24 hours at a temperature of 66 degrees Celsius steam bath. Air entrainment agent is used to toughen the bricks.
Since the concentration of calcium oxide is very high in class C fly ash, the brick is described as self cementing.
It is considered to be a good alternative to traditional mud bricks since the method of manufacture of fly ash is energy efficient that is it helps save energy, brings about reduction of mercury pollution and plus it is cost effective.
Raw materials used for the manufacture of Fly ash Bricks:
- Fly ash – which is the primary ingredient
- Sand or Stone dust – as fine aggregate
- Lime – source of calcium carbonate which results in the bricks being called “Self-cementing bricks”.
- Gypsum – to enhance the fineness of the shape of the bricks
- Cement – to increase bonding and strength
Sweden is one of the most prosperous of Scandinavian nations in Europe. It has a long history of traditions and cultural heritage. Sweden is famous for its amazing Swedish Cheese. Stockholm is a beautiful city, and its latest jewel would be the new Victoria Tower. It would be the second highest building in Stockholm after the Kaknästornet.
The name “Victoria” comes from’ the crown-princess of Sweden. Construction on this tower began in May 2009. There was a lot of debate about the final height of the building. This tower would be operated by Scandic Hotels.
