Iranian Experts Make Recyclable Prefabricated Structures Resistant to Earthquake
“One of the main needs of Iran is the light structures since these frames, in addition to resistance to earthquake reduce the weight of the structure by 50%,” said Ali Akbar Khademi, the director of business, design and development of the technological company.
He mentioned economic efficiency as another advantage of the plan, saying, “The price of these structures is 20% lower than traditional structures, while unlike prefabricated structures including canopies and the like, whether in concrete or metal form, these structures are able to save energy.”
“In the past, we used kenaf in production of these structures which caused the structure to crack; therefore, we used a type of wall based on nanotechnology to solve this problem in production of these structures,” Khademi said.
Earlier this year, a knowledge-based company in Iran had succeeded in producing a special light wall with different advantages like high impact and earthquake resistance and heat and sound insulation.
Wallcrete panels produced by the knowledge-based ‘Padideh Paydar Sanat Sakhteman’ company are light weight and proper for external and internal walls of buildings and enjoy many advantages including resistance to earthquake and fire, insulation against sound, heat and cold, high execution speed, reduction of the weight of the structure, and optimization of the internal spaces.
The light concrete panels called wallcrete are made of a composite structure and reinforced with polymer and mineral fibers by using micro-scale fillers and state-of-the-art know-how without the need for steel mesh and have high compressive and bending resistance.
Due to their suitable dimensions and weight, the wallcrete panels can be installed rapidly. The panels are connected to each other with a special glue and there is no need for water, so, in addition to saving time and cost of making mortar, a cleaner working environment is created.
Given the smooth and uniform surface and absence of many seams between the panels, the precise verticality of the wall during execution is possible, and the use of sealing tape will prevent the transfer of cracks to joinery and the wall will not need to be plastered.
