摘要本文采用了硅酸盐水泥来制造标准的硅酸盐水泥试件，研讨了养护条件和硅灰掺量对于硅酸盐水泥水化功能和微观产物的影响。在此基础上，研讨了低温情况下硅灰对于硅酸盐水泥功能的影响。和硅灰对于硅酸盐水泥水化产物和力学功能的影响。研讨结果表明：硅灰掺量的提高可以明显提高普通硅酸盐水泥初期抗压、抗折强度，改善普通硅酸盐水泥耐久性及耐水功能。当硅灰掺量为8%时，普通硅酸盐水泥抗压强度可以达到最大值。水化结果表明，养护机制可以明显的影响普通硅酸盐水泥水化产物含量，低温养护形状下的普通硅酸盐水泥水化产物变化较大，进而影响普通硅酸盐水泥的抗压、抗折强度。关键词：硅酸盐水泥；水化功能；低温；硅灰AbstractInthispaper,ordinaryportlandcementwasusedtomakestandardportlandcementspecimens.Theeffectsofcuringconditionsandsilicafumecontentonhydrationpropertiesandmicroscopicproductsofportlandcementwerestudied.Onthebasisofthis,theeffectofsilicafumeonthepropertiesofportlandcementatlowtemperaturewasstudied.Andtheeffectofsilicafumeonhydrationproductsandmechanicalpropertiesofportlandcement.Resultsshowthat,Theincreaseofsilicafumecontentcanobviouslypromotetheearlycompressiveandflexuralstrengthofordinaryportlandcementandimprovethedurabilityandwaterresistanceofordinaryportlandcement.Whenthecontentofsilicafumeis8%,thecompressivestrengthofordinaryportlandcementcanreachthemaximum.Thehydrationresultsshowthatthecuringmechanismcanobviouslyaffectthecontentofhydrationproductsofordinaryportlandcement.thehydrationproductsofordinaryportlandcementchangegreatlyunderlowtemperaturecuring,thusaffectingthecompressivestrengthandflexuralstrengthofordinaryportlandcement.Keywords:portlandcement;Hydrationperformance;Lowtemperature;Silicafume目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc516881233"摘要PAGEREF_Toc516881233\hIHYPERLINK\l"_Toc516881234"AbstractPAGEREF_Toc516881234\hIIHYPERLINK\l"_Toc516881235"目录PAGEREF_Toc516881235\hIIIHYPERLINK\l"_Toc516881236"1绪论PAGEREF_Toc516881236\h1HYPERLINK\l"_Toc516881237"1.1研讨的目的和意义PAGEREF_Toc516881237\h1HYPERLINK\l"_Toc516881238"1.2国内外研讨现状PAGEREF_Toc516881238\h2HYPERLINK\l"_Toc516881239"1.2.1国外硅灰对于硅酸盐水泥水化影响的研讨现状PAGEREF_Toc516881239\h2HYPERLINK\l"_Toc516881240"1.2.2国内硅灰对于硅酸盐水泥水化影响的研讨现状PAGEREF_Toc516881240\h3HYPERLINK\l"_Toc516881241"1.4目前存在的问题PAGEREF_Toc516881241\h4HYPERLINK\l"_Toc51688124
