Pozzolana is abundant in certain locations and is extensively used as an addition to Portland cement in countries such as Italy, Germany, Kenya, Turkey, China and Greece. 0000006835 00000 n 0000023048 00000 n This is due to the active silica in the pozzolanic material interacting with calcium hydroxide to produce a large amount of hydrated calcium silicate. 0000010213 00000 n Applicable engineering: it is more widely applied than ordinary Portland cement, Portland slag cement, Portland pozzolana cement, etc. 0000011162 00000 n 0000023227 00000 n The setting time of Portland pozzolana cement is relatively long, the initial setting time needs at least half an hour, and the final setting time needs 10 hours at most. Nel 1896 il tedesco Wilhelm Michaelis ebbe la felice intuizione di aggiungere pozzolana al cemento Portland per migliorare l’idraulicità e l’impermeabilità del calcestruzzo per formazione di silicati ed alluminati di calcio idrati. AGICO offers Portland pozzolana cement plants from 50-10000 TPD. 0000023921 00000 n Portland-pozzolana cement produces less heat of hydration and offers greater resistance to the attack of aggressive waters than normal Portland cement.
