摘要:

研究了由不同产地的高岭土经不同煅烧条件所得的偏高岭土、水玻璃类型和模数、碱含量及养护条件等对地质聚合物合成的影响规律.结果表明:某种苏州高岭土经800℃煅烧6 h活性最好,即在碱液中硅铝溶出率最大;当水玻璃模数为1.4,碱含量为10%时,制得的地质聚合物在20℃(相对湿度大于90%)的条件下养护28 d,其抗压强度达到82.5 MPa.合成地质聚合物中的偏高岭土的活性、水玻璃模数、碱含量和养护条件达到最佳匹配条件时,其抗压强度最大.

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.
