Lightweight Concrete Paver Blocks Manufactured in Iran by Using Oxide Nanoparticles

‘Aptus Iran’ company has made the product which is a multi-functional concrete comparatively lighter than its counterparts with extraordinary paintability, low weight, water-proof feature, and high abrasion resistance.

These intrinsic properties originate from the inclusion of oxide nanoparticles in the cementitious matrix.

Adding the oxide nanoparticles of pozzolanic nature has improved compressive, bending and tensile strength of the product and durability and decreased its permeability.

The special nano-based blocks can be used in interior decoration or building exterior architecture and cement coating for restaurants, food courts, coffee shops, building facades.

In a relevant development in April, a faculty member of Islamic Azad University’s Tabriz branch in Northwestern Iran succeeded in designing and manufacturing fibrous nano polymer bricks for construction of buildings which enjoy waterproof properties.

“The nano-gypsum fiber waterproof panels have been developed based on the state-of-the-art technologies in the world and they enjoy compressive strength of at least 3 mega pascals, with a low density of about 400-550 kg/m3,” said Yousef Zandi, the researcher of the project.

Noting that the polymer bricks enjoy many good features, he said that they do not need plaster and soil, absorb adequate water when used in construction operations and show excellent adhesion with cement and high thermal insulation.

Zandi added that the gypsum nanopolymers are as light as wood and they have special properties like very low density (400 to 550 kg per cubic meter), heat insulation, sound insulation, and greater resistance to freezing and erosion, saying that the use of these gypsum nanopolymers in construction reduces over 30% in construction costs and more than 70% in cooling and heating costs.
