    摘要:

    研究了热活化煤矸石的细度和掺量对水泥浆体流动度、凝结时问,水泥硬化浆体抗压强度、化学结合水量和微观结构的影响.结果表明:提高热活化煤矸石的细度和掺量,水泥浆体的流动度降低,凝结时间延长;水泥浆体的抗压强度和化学结合水量随热活化煤矸石细度的提高而增大,随掺量的增加而减少.热活化煤矸石的细度和掺量对水泥硬化浆体的孔结构分布和形貌也有较明显的影响.

    Abstract:

    The influence of fineness and content of coal gangue on the properties of cement pastes was studied.The results show that the fluidity of the cement pastes reduces with the increasing of fineness and content of coal gangue,but the setting time prolongs.The compressive strength and the chemically combined water content of the hardened cement pastes continuously increase with improving fineness of coal gangue during curing age.But they decrease with increasing the content of coal gangue.The fineness and content of coal gangue have also influence on the pore distribution and SEM figure of the hardened cement pastes.
