A knowledge-based company has developed a concrete using nanoparticles with higher abrasion resistance and lighter weight.
The domestic nanoconcrete is produced in various shapes for different industries and infrastructures, as well as for flooring parks, sidewalks and roads.
Behdis Saman Amin Housing Mass-Production Company is the producer of this type of concrete, the news portal of Vice Presidency for Science and Technology reported.
The company said the most important feature of this type of concrete flooring is its high resistance to abrasion, weather changes and impact.
The ease of implementation without the use of special machinery, applicability with wet or dry mortar, easy repair and durability in withstanding extreme pressure are among other advantages of this nanoconcrete.
The nanoconcrete helps eliminate dead load and offers better fire resistance and easy cutting.
Behdis Saman Amin Housing Mass-Production Company has used additives such as nanoparticles to produce a superior concrete, apart from cement, water, aggregate and concrete glue.
The knowledge-based company was established in the fiscal 2011-12 for boosting the quality and speed of mass housing projects.
The company has partnered in numerous construction projects, assisting them in terms of design and production of new concrete products to enhance the country's construction culture.
Nanocoatings Enhance Building’s Beauty, Lifespan
Adomestic knowledge-based company has produced nanocoatings for protecting buildings from damages and extending its lifespan.
Nanocoatings produced by Sepahan Nano Faraz Company can help prevent the formation of scales and flakes on a building’s surface, reduce the growth of fungus, mold and algae, and block moisture from penetrating a building’s wall, the news portal of the Vice-Presidency for Science and Technology said.
Stains and oily pollutants mar the beauty of buildings’ façades made with concrete, wood, brick, tiles and other materials, which can be preserved with the help of the nanocoating.
Also known as ceramic coating, the nanocoating is applied as a surface layer in both liquid and solid forms to repel polluting dry particles, water, oil and dirt.
Revitalizing dark stone surfaces, protecting internal and external walls, especially of public places like schools, hospitals, mosques and ancient monuments, and helping construction contractors and owners optimize energy consumption are the most important benefits of using this domestic product.
Depending on the type and mode of application, a property’s mechanical and functional efficiency is retained and the appearance of materials and structures is preserved.
The use of waterproof coatings on all kinds of building materials will reduce the excessive accumulation of water on their surface and increases a building’s lifespan.
Recently, the development of products based on nanotechnology has expanded significantly in the domestic construction sector and numerous knowledge-based companies are active in this field.
Domestic Nanocomposite Insulation
A domestic company has produced insulation with nanotechnology that can be used in wide areas of the construction and industrial sectors.
Insulation produced by Sazeh Paidar Elahie Company can be installed in the boiler rooms and cut energy consumption by an estimated 60%. The product is a foam-like elastomeric nanocomposite useful for thermal and acoustic insulation.
The insulation, produced from acrylonitrile butadiene rubber/polyvinyl chloride (NBR/PVC) polymers, is considered one of the most widely used insulations in different industries, buildings, hotels, towers, hospitals, petrochemical firms and refineries. The insulations are produced in different forms of sheet and pipes and as a closed cell structure are good for insulating heating and cooling pipes, channels, air conditioning systems, utility equipment and tanks.
They are durable and have a longer life than normal insulations due to their solid resilience to humidity and penetration of water vapor.
Another important advantage of this nanocomposite insulation is germicidal properties in environments with high humidity and temperature fluctuations.
Standard tests conducted on this type of insulation compared to simple closed-cell elastomeric insulation without nanoparticles show that the surface of nanocomposite insulation is not suitable for the growth and proliferation of microorganisms, which is due to its antibacterial properties.
As such, this insulation can be used in sanitary areas, water and air channels, coolers or places prone to the growth of microbes and bacteria.
Nanocomposite insulations have much lower thermal conductivity than glass wool.
The coefficient of thermal conductivity of this nanocomposite insulation is about 0.0368 K/W/m, which is less compared to glass wool insulation.
Also, closed-cell elastomeric foam insulation has very high resistance coefficient against water vapor penetration ≥ 7000 μ, which is of much higher value than mineral wool insulation. It is more effective in preventing corrosion of insulated metal surfaces.
