摘要:
运用激光共聚焦显微镜(LSCM)和扫描电子显微镜(SEM)等测试手段对中国山东省潍坊市虎头山的白云质灰岩HTS-3、HTS-5、HTS-8、HTS-10、HTS-12和HTS-13的岩石结构特征进行分析,并采用混凝土微柱法(RILEM AAR-5)和碱-碳酸盐反应快速鉴定法(NRAA 02)对岩石的碱-碳酸盐反应活性进行检测。结果表明:泥晶白云质灰岩中,伊利石含量、白云石含量和白云石-基质间的间隙是影响碱白云石反应(ADR)膨胀的重要因素,伊利石的含量越高,越有利碱迁移至白云石表面发生碱白云石反应; 白云石含量越高,碱白云石反应位置增多; 白云石-基质间的间隙越小,碱白云石反应生成产物越受限,结果均使得ADR膨胀增大。
Abstract:
Laser scanning confocal microscope(LSCM)and scanning electron microscope(SEM)were used to analyse the textures of the dolomitic limestones HTS-3,HTS-5,HTS-8,HTS-10,HTS-12 and HTS-13,which were derived from Hutou mountain at Weifang of Shandong Province in China.The alkali-carbonate reaction of the dolomitic limestones was tested according to concrete microbar method(RILEM AAR-5)and rapid identification of alkali carbonate reaction(NRAA 02).Results showed that the contents of illite and dolomite and gap between dolomite and matrix were the key factors which determined the alkali-dolomite reactivity(ADR)of the dolomitic micrite.The higher the contents of illite or dolomite,the higher were the alkali-dolomite reactivities.Smaller gaps between dolomite and matrix might cause larger alkali-dolomite reactivities.
