Iran-Made Hydrophobic Powder Strengthens Clay, Cement Structures
“In our company, we succeeded in production of a hydrophobic additive product, one type of this product is used for cement mortars and the other type is used for clay mortars,” Ehsan Sadeqi, the chairman of the board of directors of the technological company stationed at the Science and Technology Park of Kashan University, told ANA.
He added that one-twentieth of the additive is added to cement or clay mortar in a dry form, and then by adding water, the mortar is ready.
“The surface of the mortar and its inside will be completely hydrophobic, which means that water does not penetrate into the cement or clay,” Sadeqi said.
In a relevant development in July, a group of engineers from a technological company in Iran had also designed and manufactured earthquake-resistant prefabricated houses which are movable and the safest place during tremors.
“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.
