Sol–gel-entrapped pH indicator for monitoring pH variations in cementitious materials

Sol–gel-entrapped pH indicator for monitoring pH variations in cementitious materials

Sensors for pH evaluation of concrete were made by a sol–gel process with alizarin yellow as pH indicator. The optical absorbance was measured with a visible spectrophotometer coupled with optical fibers. Results showed that the sensors had good reversibility, reproducibility, and fast response time...
