| 摘 要： | 研究了膨润土的种类和掺量对水泥硬化浆体抗压强度、Ca(OH)2含量、微观孔结构分布和对硬化浆体的水化形貌的影响。结果表明:掺钠基膨润土的水泥浆体抗压强度高于掺钙基膨润土的水泥浆体抗压强度。提高膨润土掺量,抗压强度和Ca(OH)2含量均降低;膨润土的种类和掺量对硬化水泥浆体的孔结构分布和形貌也有明显的影响。 |
| 关 键 词： | 膨润土 抗压强度 水化硬化 |

| Abstract: | The influences of variety and content of bentonite on the properties of cement pastes was studied.The results show that the compressive strength of sodium-based bentonite was higher than that of calcium-based bentonite.The compressive strength and the Ca(OH)2 content of the hardened cement pastes reduce with the increasing of the content of bentonite.The variety and content of bentonite also have influence on the pore distribution and SEM figure of the hardened cement pastes. |
| Keywords: | bentonite compressive strength hydrating and hardening |
