In the summer, an old rural farm is more pleasant than a modern building in the city, but why this is the case remains a mystery. The thermal and hygrometric properties of historic buildings may be improved by using traditional construction materials and natural stones. It’s sad that they don’t have the technical know-how to have a footing in the construction industry. As part of the OEHM project, you’ll be doing research on natural building materials. For sodium naphthalene sulphonate malaysia this goes perfect.
Why is this happening?
In today’s environment, every building job begins with a computer simulation. Industry-created building materials, on the other hand, lack these technical characteristics. To fill up this gap, we’re doing study on local traditional materials as part of our project.”
In the absence of these materials, is it feasible that manufacturers are not interested in this information?
An important observation concerning today’s buildings is that they are too insulated from the inside out. A lack of thermal mass (a mass of materials that may act as a heat regulator) is the fundamental cause of the rise in temperature in modern constructions.
Using typical building materials in new construction means that you will be both hot and cold in the summer and winter, respectively. So you need cooling and heating to keep the temperature comfortable.
It’s a far less serious problem with constructions built using ordinary materials in the past. In the summer, Seville is one of Europe’s hottest cities, thanks to the city’s historic buildings and cathedrals. Manufacturers are increasingly turning to these already-existing buildings for inspiration when designing new ones.
A further area of interest exists. Greenhouse gas emissions have a substantial influence on the building sector. Material transportation has a significant influence on the environment. In order to reduce the environmental impact, the use of local stones encourages short circuits.
What are the specifics of the subject matter?
A clay brick factory and four natural stone quarries are included in the OEHM project, one of which is granite and the other three are limestone.
What are you studying with these stones and bricks?
AG: Thermal and hygrometric tests are two of the most often used methods for determining the condition of these rocks. A substance’s capacity to absorb moisture may be assessed using hygrometry. The residence is generally closed throughout the winter, so you have to cook, wash dishes, and perspire a lot. All of this contributes to an increase in room humidity, which has a negative impact on comfort levels. When it comes to moisture absorption, certain extremely tiny porous stones are completely ineffective. This buffering effect may last up to four months for certain other materials, especially porous ones like limestone and clay.
You need to know what the best method is to achieve the specs you want
AG: The quarries supply us with 5 cm cubes to examine for ourselves. An investigation of heat transfer is carried out using the hot wire approach. This is done by placing a post-it-sized probe between two cubes of the same stone. One side of the stone is heated while the other side is observed for signs of warming. Using a mini-furnace, we are also testing the thermal capacity of the stones by putting even smaller samples 5 mm apart. Our ability to predict the stone’s behavior after heating is made possible by this measurement.
