The REFRAJET® Addmix technology is an innovative injection system that was developed specifically for the installation of cement-free sol-gel bonded refractory concretes of the REFRAJET® Nanobond type.
The injection system creates a reactive aerosol that is injected centrally into the continuous flow of dry gunning mix material. A liquid binder can be added to the pre-wetted dry material via a conventional nozzle system at the end of the deliver hose.
Pre-wetting of the dry gunning mix offers several advantages, such as reduced dust generation at the gunning nozzle, less material rebound – particularly during overhead work – plus enhanced bonding to refractory surfaces.
Moreover, the concrete's cold crushing strength and cold modulus of rupture are increased, porosity is reduced, and a denser concrete structure is obtained.
The process has been optimized for cement-free shotcretes of the REFRAJET® Nanobond type, but it can also be used for many other concretes from Refratechnik's product range.
The Iranian cement industry’s fall from grace has turned into a continuous freefall.
Tehran Police will equip its car fleet with eco-friendly vehicles to help protect the environment and curb air pollution.
Refratechnik Ceramics GmbH, Germany (formerly BURTON), and HK-CERAM Kft., Hungary, are among the world’s leading companies for the design, development and manufacture of refractory products for the ceramics industry.
The Fourth Isfahan Cement Expo opened on Thursday and is scheduled to run until Saturday.
There is no denying that a large portion of the Iranian economy, if not all of it, is steered by the government.
Pakistan Cement Manufacturers Association is urging the Pakistani government to slap up to 20% of import duties on Iranian cement, claiming that Iranian producers are “dumping” the industrial material in border markets.
