- Abstract:
-
The effects of metakaolin, water glass type and modulus, alkali content and conservation conditions on the synthesis of geopolymers obtained from kaolin from different sources under different calcination conditions were studied. The results showed that a certain Suzhou kaolin had the best activity after calcination at 800°C for 6 h, that is, the dissolution rate of silicon aluminum was the largest in lye. When the water glass modulus was 1.4 and the alkali content was 10%, the prepared geological polymer was cured for 20 days at 90°C (relative humidity greater than 28%), and its compressive strength reached 82.5 MPa.
