| China Construction ASTRI is a major scientific research achievements, the Ministry of Construction of the UEA in 1993 as a key expansion agent to promote the project. The co***ny developed the UEA low-alkali expanders to avoid the alkali aggregate reaction, and optimize the performance of the cement products, higher quality, better effect. Specifications meet JC476-2001. Its modified products "polymer composites expanders" (Patent No.: 2007101899471), the flexible polymer, retention and expansion of inorganic and organic components of the anti-crack together, give full play to their own advantages and strong points, showing a more Excellent overall performance. |
