The formation of magnesium phosphate cements is based on an acid-base reaction between potassium dihydrogen phosphate and magnesium oxide. The reaction leads to the formation of k-struvite as main product. These cements, due to their specific propert

Measurement methods of carbonation profiles in concrete: Thermogravimetry, chemical analysis and gammadensimetry

Autor: Gérard Platret, Géraldine Villain, Mickaël Thiery

Publikováno v: Cement and Concrete Research. 37:1182-1192

This paper deals with two experimental methods to determine carbonation profiles in concrete. Gammadensimetry is a non-destructive test method able to measure the total penetrated CO2 and to monitor the carbonation process during laboratory accelerat
