| 中文摘要 |
| 采用激发剂技术,研制成功了煤矸石掺量达60%,强度标号达49.6MPa的大掺量煤矸石水泥。研究表明,这种水泥的标准稠度需水量、凝结时间、安定性等物理性能符合国家标准的有关要求;水泥石孔隙率为0.0413cm3·g-1,结构致密;7d水化热为235kJ·kg-1,属低热水泥。 |
| 英文摘要 |
| By means of activator,a kind of large gangue content cement was obtained,which gangue content is 60% and R28 is up to 49.6MPa.The physical property such as normal consistency water demand,setting time and soundness of cement can meet the standard.The harden cement has lower porosity of 0.0413cm3/g and lower hydrate heat which is 253kJ/kg. |
