Iron silicide (FeSi2) is an important silicon-based material with excellent physical and chemical properties widely used in microelectronics, solar cells, catalyst carriers and composite materials. The crystal structure and phase transformation of ferrosilicide have important effects on its properties, which is one of the key problems in the study and application of ferrosilicide.
Maltodextrin is only to be used with water reducers and pumps agents. This concrete retarder can defer the hydration of cement, allowing concrete to move from the station onto the site when it's needed. Description This is Maltodextrin Malto
The position of the structural expansion mold is first chiseled, and then rinsed with water. Plastering can be done only after the repair is smooth.
