Iranian Company Exports Prefabricated Cement-Covered Walls to 7 Countries
“Production of cement nanocomposite sheets containing cellulose fibers and autoclaved nanomaterials is one of the research fields of our company, and we produce and market all types of cement fiber sheets,” said Shobo Salehpour, the director of research and development department of the knowledge-based company.
“Wood design cement fiber sheets, which replace wood in facades, are more resistant than wood and resist against biological factors. One of the advantages of our company's sheets is that they are dry and can be used in facade construction in various weather conditions including freezing and high humidity environments,” he added.
Noting that the sheets have large dimensions of 2.4 x 1.2 meters and a thickness between 6mm to 20mm, Salehpour said, “The sheets enjoy very high resistance and light weight. Its heat transmission is high and its sound transmission is very low, and they are also very biocompatible.”
“Previously, asbestos was used to produce such sheets but we replaced them with cellulose fibers due to the health problems. These fibers have different origins, including textile fibers, leaf fibers, and stem fibers.”
In March 2023, another knowledge-based company in Iran had also produced 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.
Also, due to the optimal dimensions of the wall and the existence of special connections due to the integrated function of the wall, the weight and dimensions of the wallcretes are reduced to less than 50% of the normal walls.
