Iranian Company Makes Anti-Seismic, Environment-Friendly Construction Product
“The product is a wood-reinforced lightweight composite prefabricated roof. The design and construction of prefabricated wooden composite slabs or panels for roofs and walls can have an acceptable structural role in addition to lightening, and by using wood in the panels, it can minimize the cracks caused by bending forces,” Asqar Anvari, a faculty member of the Islamic Azad University’s Maraqeh branch, a PhD in civil engineering and chairman of the board of directors of Fanavar Hesabgaran Sazeh Pardaz company stationed at the incubator center of the university, told ANA.
He explained that the use of lightweight concrete along with rebar or fibers in these panels is effective in increasing mechanical resistance, he added, “Other prominent features of this product include high degree of prefabrication, sound and thermal insulation, low sensitivity to vibration, low dead weight, and reduced sensitivity to change.”
“The composite roof, which is created from the combination of different materials in one element, has several common types in our country, the steel deck and concrete deck are the most famous ones,” Anvari said.
In a relevant development in May, researchers of an Iranian knowledge-based company had also succeeded in designing and manufacturing prefabricated concrete parts which are eco-friendly and resistant to earthquake and reduce energy consumption.
“One of the products of our company is GRS precast concrete parts. These pieces have a cement base and their thickness is 2-3 cm and they are produced in dimensions of 30cm*30cm to 3m*3m,” Hamed Anahid, a member of the board of directors and the managing-director of the knowledge-based company, told ANA.
“It has suitable mechanical properties like compressive and fracture resistance, tensile strength, wear resistance, resistance to weather conditions (melting and freezing), resistance to corrosive and acidic substances (caused by rain) and having integrity when broken,” he added.
Noting that another product of the company is called microcement, Anahid said, “This cement-based product consists of mineral, organic and polymer materials and can be applied on horizontal and vertical surfaces due to its high adhesion.”
“Microcement concrete is 30 mm thick and is used for indoor and outdoor environments and can be used on wood, glass, and stone surfaces to create a surface without seams, cracks, and discoloration and it can last up to 15 years,” he noted.
Anahid described resistance to live load, impact, scratches and chemicals, easy cleaning, waterproofness, fast execution without destruction, use of natural and environmentally friendly materials as the most important advantages of using the product, saying, “This product is now exported to different countries, including the UAE, Oman, Iraq, Azerbaijan and Spain, due to competitive advantages compared to similar foreign samples like good quality and reasonable price.”
