Knowledge-Based Firm Produces Construction Materials from Natural Stone Waste
“Nano Fanavaran Sakhteman company was established with the idea of producing knowledge-based construction materials, and the first projects were defined as the production of self-cleaning water-repellent nano-coatings, colored concrete bricks, artificial stone, and lightweight fiber cement sheets,” Mohammad Rayeesi, the managing director of the company, told ANA.
“We set up the stone research center at Islamic Azad University’s Khomeinishahr branch because there are several industrial towns around Khomeinishahr that are active in the field of natural stone processing,” he added.
“One of the environmental problems created by these towns is a large amount of waste that is created by natural stone processing factories, and therefore, we decided to produce colored concrete bricks, artificial stone and cement slabs of fiber style with the waste,” Rayeesi 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.”
