Iran's Building Industry to Witness Durable Progress by Home-Made ‘New Slab Dal Puzzle’
“In this invention (new slab dal puzzle), hollow molds made of very low-weight plastic or unolith are used in the middle of the thick parts of the roof in the shape of puzzles,” Alireza Grayli told ANA on the sidelines of Asreh Omid Event in Tehran.
He added that by using these molds no useless concrete exists anymore and it reduces the weight of the roof and increases its rigidity and bending resistance.
When it comes to construction, plastics have been extensively used by various construction companies. The components such as hinges, screws, and bigger construction parts are made from plastic and are used in wall covering, electric wiring, waterproofing, flooring, and decoration.
Asreh Omid Event was held in Tehran's Mosalla from May 29 to June 1, 2022.
The event aimed to exhibit new achievements and products in the technological and innovation arenas in line with opening new windows towards strengthening the idea of creating ground for knowledge-based businesses at the 40th anniversary of the establishment of the Islamic Azad University.
Some 3,000 knowledge-based companies, laboratories, research centers, and startups took part in Asreh Omid Event.
