Ensure Quality Bricks for Your Home Construction
It is obvious that every one of us wish to have a perfect home to live in for decades. A reliable and professional builder helps you in building your dream home. However, it is to be ensured that the structure, materials and quality of the work are at their best in order to get a house that lasts for years.
Different types of bricks used
Various types of bricks such as common burnt clay bricks, sand lime bricks, fly ash bricks, concrete bricks, and fire clay bricks are used for construction of buildings. Among these types, common burnt clay bricks are recommended for building a house. Red clay bricks have been in use from many years for home constructions. The red bricks are much heat resistant and hence are preferred keeping Hyderabad heat in mind.
Many people get confused while choosing between the clay and cement bricks. Both have their own unique features. But, red clay bricks are more fire resistant than the cement ones and hence are mostly preferred. They are also stronger than the cement ones. However, it is the best basic foundation that makes the main structure good and strong. So you need not conclude that a building made of cement bricks is less stronger provided that the foundation is good.
However, some apartments in the city are being constructed with hollow cement bricks these days. They are light in weight and have bigger dimensions compared to others. But there are certain issues of using these hollow cement bricks. It is not possible for nailing the walls (nails will not have good grip) as the brick is hollow. It is also difficult to replace them during repairs in the walls as you cannot adjust the size of the hollow bricks accordingly (they are not easily available too). However, they are mostly preferred to build common areas such as corridors, compound walls etc.
Guidelines for checking the quality of bricks
Neglecting to hire a qualified builder is a big mistake. You should ensure that quality products and tools used for construction. Here are some guidelines which can help you in checking their quality.
The first and the foremost thing you check is their appearance or size. They should be uniform in size with sharp edges and angles. The bricks must be smooth and rectangular in shape. This is because the accurate size and shape of the bricks ensures a neat work.
The bricks should not have any cracks, chips, and warpages. They must be free from large particles of limestone and lumps of any other organic matter.
Good quality bricks are hard and well burned. One of the easy ways to assess the brick quality is to strike two bricks together. A hard ringing sound ensures that the bricks are strong enough for any ordinary work. Remember that a dull sound ascertains that the brick is soft or shaky.
The other major thing you need to consider is the level of water absorption by the brick. Weighing the brick before and after immersing it in water for 24 hours, helps you to know the absorption rate. The average water absorption should not be more than 20% of the brick’s own dry weight. Good quality bricks absorb not more than 5% and hence are best suitable for foundation and outside walls.
When a scratch is made on brick surface with a finger nail, it should not leave any impression on the surface. This indicates that the brick is hard enough.
The brick should not break when dropped from a height of 1m. When you drop a light-weight and a heavy brick from the same height, the heavier one is found to break more easily. So light-weight bricks are mostly preferred.
Why is Brick Construction so Popular?
There are many advantages when bricks are used as part of the construction. The following list presents some of the most common advantages when using bricks instead of other construction materials.
Bricks offer natural and a variety of colors, including various textures.
Brick is extremely durable and perhaps is the most durable man-made structural building material so far.
A brick is so strong, that its composition provides excellent wear resistance.
Bricks offer excellent high compressive strength.
The ability to release and absorb moisture is one of the most important and useful properties of bricks, regulating temperatures and humidity inside structures.
When prepared properly a brick structure can give a fire protection maximum rating of 6 hours.
Bricks can exhibit above normal thermal insulation when compared to other building materials. Bricks can help regulate and maintain constant interior temperatures of a structure due to their ability to absorb and slowly release heat. This way bricks can produce significant energy savings, more than 30% of energy saving when compared to wood.
The brick sound insulation is normally 45 decibels for a 4.5 inches brick thickness and 50 decibels for a nine-inch thick brick.
Efflorescence forms on concrete structures and surfaces when soluble salts dissolved in water are deposited and accumulated on surfaces forming a visible scum.
