摘　　要：研究了水灰比、胶砂比及脱硫灰掺量对砂浆稠度和砂浆强度的影响,结果表明：随着水灰比的提高,砂浆稠度提高,而强度下降;随着胶砂比减小,砂浆稠度降低,而强度提高。试验配比下,脱硫灰掺量为15%-35%时,制备的脱硫灰砂浆28天抗压强度最高60.6 MPa,最低25.4 MPa。最后从微观角度分析了脱硫灰掺入后对砂浆的强度影响。Effects of water cement ratio,cement sand ratio and the desulfurization ash content on mortar consistency and mortar strength were studied in this paper.The results were as follows：with the increase of the water cement ratio,the consistency of mortar improved,and intensity decreased;with the cement sand ratio decreasing,mortar consistency reduced,strength increase.Under the experimental formula,the desulfurization ash mortar prepared 28 day compressive strength was up to 60.6 MPa,and a minimum of 25.4 MPa with the desulfurization ash dosage of 15 %-35 %.The influence on mortar strength after the incorporation of desulfurization ash from a microcosmic angle was investigated in the end.
