| 中文摘要: |
| 通过实验验证重晶石对高贝利特熟料的活化效果。实验结果表明,当重晶石掺量为0~2.4%时,熟料中C2S alpha H含量与重晶石掺量线性正相关；适量重晶石可显著提高C2S含量40％熟料的3d、7d抗压强度,提高C2S含量20％熟料的3d和28d抗压强度；C2S含量约20％的熟料1450℃煅烧较充分；C2S含量约40％的熟料1400℃煅烧充分；C2S含量约70%的熟料1400℃过烧；重晶石掺量高于2.4%时,生料易烧性显著变差；重晶石掺量小于2.4%时,不影响熟料中的方镁石含量；重晶石掺量1.6%时,熟料标准稠度和凝结时间无显著变化。 |

| The activation effect of barite on high belite clinker was verified by experiments. The experimental results show that when the barite dosage 0~2.4%, the content of C2S alpha H in the clinker is linearly positively correlated with the barite dosage; barite significantly improve the 3d and 7d compressive strength of clinker with 40% C2S content, and improve the 3d and28d compressive strength of clinker with 20% C2S content; clinker with about 20% C2S content is calcined at 1450℃; clinker with about 40% C2S content is fully calcined at 1400; clinker with about 70% C2S content is overburned at 1400℃; when the dosage is higher than 24%, the burnability of the raw meal is significantly reduced; when the barite dosage is less than 2.4%, it does not affect the content periclase in the clinker; when the barite dosage is 1.6%, there is no significant change in the standard consistency and setting time of clinker. |
