摘 要:研究了纤维素絮凝剂、多聚糖絮凝剂在单掺和复掺情况下对水泥砂浆抗压强度的影响,并采用X-射线衍射(XRD)、傅立叶红外光谱分析(FTIR)、扫描电镜(SEM)对试样进行了微观分析。结果表明:两种絮凝剂单掺会降低砂浆的早期强度,但能够提升后期的抗压强度,而两种絮凝剂复掺会降低早期和后期的抗压强度。
Abstract: The influence of cellulose flocculant and polysaccharide flocculant on the compressive strength of cement mortar under single and compound mixing conditions was studied. X-ray diffraction (XRD), Fourier infrared spectroscopy (FTIR), and scanning electron microscope (SEM) were used for microscopic analysis of the samples. The results show that the two of single-doped flocculants can reduce the early strength of the mortar, but improve the compressive strength in the later stage. Both of the early and late compressive strength are reduced when the two flocculants are mixed.
