What is the pH of saturated Ca(OH)2 at 20degrees celcius.?

Calcium hydroxide is the cheapest strong base available and is generally used for industrial operations where a high concentration of OH- is not required. Ca(OH)2 (s) is soluble in water only to the extent of 0.165 g Ca(OH)2 per 100.0 mL solution at 20 oC. What is the pH of saturated Ca(OH)2 (aq) at 20 oC?
