In the case of natural stone coverings, ceramic tile, plastic and metal materials are of particular importance the following parameters

Coating layer

Its function is to protect the building from the weather, in addition to the representative under the architectural coating. The requirements that have to meet the coating materials are:
high mechanical strength and thermal stress (resistance to shock, temperature variations, etc.).

Water tightness
physical and aesthetics fastness over time
resistance to the wind (pressure and depression)
versatility of the commissioning work.

In the case of natural stone coverings, ceramic tile, plastic and metal materials are of particular importance the following parameters:
Slab weight.

Dimensions of the slabs

On the nature and magnitude of deformation affects not only the magnitude of loading, but also the rate of load application

The mechanical properties of building materials
The mechanical properties reflect the ability of bodies (material) to resist the force (from mechanical stresses), heat, shrink, or other stresses without breaking the established structure. In turn, energized understood measure of the intensity of internal forces generated by the action of loads, temperature changes and other factors or causes. Virtually stress is defined as the inner force per unit area, with a mean force of the inner strength of the particles located on one side of the site, the particles that are on the other side of this site. Usually determined by calculation the normal (perpendicular to the plane) and shear stress expressed in MPa in SI.

The mechanical properties are separated by the deformation and strength.

Characterize the deformation properties of a material’s ability to change the shape or size without any variation in the magnitude of its mass.

Deformation – changes in volume or shape of solid or plastic body without weight change. The principal types of deformation – tension, compression, shear, torsion and bending. All of them may be reversible or Read the rest of this entry »

How they maintain “Todaiji Temple”, the greatest edification of Wood Temple in the World

Todaiji Temple, the greatest edification of Wood in the World

The great temple Todaiji East is an impressive Buddhist temple made from wood found in Nara, Japan. A pagoda that houses a giant statue of Buddha and the temple also currently serves as Kegon school of Buddhism. This structure holds the world record as the largest wooden building in the world, but is 33% smaller than the original monument.

This type of building in wood called Pagodas, striking five-story buildings up and, despite its antiquity and simplicity in extructura are able to withstand earthquakes much more modern buildings collapse because wood tends to warp when you put a lot of strength, but is also flexible enough to absorb the seismic stress.

The building of this architectural complex, located in the city of Nara, was started around the year 743. Inside, they worshiped the Daibutsu, a colossal statue of Buddha 15 meters tall and made of bronze gilt., Completed in 751. Since its inception the main buildings have been restored several times due to earthquakes and wars suffered in this area, the first of these restorations took place in 1180 when they were destroyed during a war. Were restored by the Buddhist priest Choge using a new architectural style called Daibutsu-yo. However, war again, destroyed the main buildings of the complex in 1567, preserved at present, Read the rest of this entry »

Keep your Poor covered & see the benefits of swimming pool covers

Benefits of swimming pool covers

Covers or solar pool covers are used primarily to maintain or achieve the temperature of the pool water. Passive solar home heating is a huge advantage for cost savings. The solar blankets can raise the temperature of pool water up to fifteen degrees. On the other hand, solar pool covers also hinder the evaporation of water during the hot season, reducing the water consumption during the season.

The most common is called a blanket of bubbles. The cover floats on the pool water by concentrating the energy of the sun’s rays on the surface of the cover, but could get a temperature rise of 4 or 5 degrees.

The blankets or solar pool blanket are made of polyethylene of 400 microns and usually comes in blue, everything is welded together and cooked reinforcements, should be placed on the surface (parts of the bubbles down while smooth side should be visible). Once the water Read the rest of this entry »

Reduce your heating bills and air conditioning with thermal insulation of ceilings (INSULATION FOR ROOFS)


Reduce your heating bills and air conditioning with thermal insulation of ceilings.

The ceiling insulation of a home are crucial to avoid heat loss during winter.

In many cases, much of the energy consumed for heating is lost unnecessarily due to poor insulation of homes, significant heat loss through a bad closing doors and windows, etc..

Recent studies show that energy loss of a home with a good roof insulation can reduce by 35% in heating costs in winter or Read the rest of this entry »

Polyurethane Foam Spray or by the injection method, provides an excellent isolation.

Polyurethane Foam Spray :

Polyurethane Foam Spray or by the injection method, provides an excellent isolation.

This foam layer can be applied to different surfaces: The application includes tanks, pipes, cold rooms, flotation elements, Construction. It is particularly suitable for ceilings and walls.

The polyurethane is presented as a solution for the construction of new buildings and rehabilitation of buildings, especially in covering these, which is the part where you lose more heat, seal all sorts of irregularities and cracks, leveling inequalities added little weight to the Read the rest of this entry »
