Model: HJL-C
Test method: ISE( Ion Selective Electrode)
Test index: Alkali content of concrete and raw material( equivalent of Na2O percentage)
Description
The alkali ( Kalium, Na ion) will react with active silica in the aggregates under specific humidity environment condition, thus will result concrete structure expansion and cracking, so the alkali content test is very important for concrete quality assessment, the concrete rapid alkali content tester is kind of very important concrete durability test instrument.
Standards: CECS53:93, CECS220: 2007
It can test fresh concrete, wet concrete, hardened concrete powder sample etc, concrete raw material( cement, additive).
