Abstract
The effect of the aqueous chemistry on the mechanical strength of chalk has been studied extensively at<br>the University of Stavanger. At high temperatures (~130°C) chalk exposed to seawater is significantly<br>weaker compared to chalk exposed to distilled water as considering the hydrostatic yield strength and the<br>following creep phase
