GB/T 21236- 2007 

Ever wondered about the GB/T 21236-2007 fine greasepaint that enhances the strength and continuity of concrete structures? That is silica cloud for you a derivative of silicon essence or ferrosilicon amalgamation product. In China, the quality and specifications of this material are governed by the standard GB/ T 21236- 2007, named” Silica Cloud from Electric- Furnace”. Let’s dive into what this standard entails and why it matters. 

What’s Silica Cloud? 

Silica cloud, frequently appertained to as microsilica, is a derivative of producing silicon essence or ferrosilicon blends in electric bow furnaces. It’s a fine, fine material composed of unformed silicon dioxide. Due to its ultrafine patches and high pozzolanic exertion, silica cloud is extensively used to enhance the parcels of concrete and other construction accoutrements . 

Product of Silica Cloud GB/T 21236-2007

During the product of silicon essence or ferrosilicon blends, a silica cloud is generated as a gas. When this gas is cooled and collected through condensation, it forms fine patches. These patches are also captured using dry dust collection bias, performing in the silica cloud product 

Operations of Silica Cloud 

Silica cloud is a protean material with several operations. Concrete improvement Improves strength, continuity, and resistance to chemical attacks. Refractory Accoutrements Used in the product of high- performance refractory products. Oil Well Grouting Enhances the parcels of oil painting well grouts. Fiber Cement Products Improves the continuity and strength of fiber cement boards. 

Overview of GB/ T 21236- 2007 

Purpose and compass
