Cracking concrete expansion

Concrete cracking expanders uses: marble, granite mining and cutting. With HSCA mining and cutting marble, granite, blocks the finished product rate increased by 2-3 times higher than blasting method, because no vibration into a plate rate can be doubled. Crushing and demolition of concrete structures: for inappropriate use of blasting works, you can use HSCA broken and removed. Without downtime, without interrupting traffic, safety and reliability. Expanders Performance: 1, Volume Low: 6 to 8 percent, its expansion rate is greater than the UEA (commercially available) Volume expansion rate of 12%; 2, low alkali content: (K2O + Na2O) content of 0.3 to 0.4 %, well below the 1.7 ~ 2.2% U-type expansive agent, and its significance; 3, due to the volume reduction does not affect the early strength and late strength, truly equivalent alternative cement; 4, does not increase the slump of concrete losses, has good workability.
