摘   要：为了探究盐渍土环境下硫酸盐侵蚀-干湿-高低温-冻融循环作用对混凝土中SO42-传输的影响，通过室内加速试验模拟了盐渍土环境，研究了多种因素循环作用下水胶比和玄武岩纤维掺量对混凝土中SO42-浓度的影响，并基于Fick第二定律建立了SO42-扩散系数时变模型。结果表明：试件相同深度处的SO42-浓度随着循环次数的增加而基本增加；随着深度的增加，SO42-浓度基本先降低后趋于稳定；随着循环次数的增加，SO42-侵蚀深度基本增加；在相同循环次数下，随着水胶比的降低，SO42-浓度降低；随着纤维掺量的增加，SO42-浓度基本呈先降低后增加的趋势；所建立的多种因素循环作用下混凝土的SO42-扩散系数时变模型精度较高。Abstract: In order to investigate the transport law of SO42- in concrete under the conditions of sulfate erosion-dry-wet-high-low temperature-freeze-thaw cycle in saline soil environment, the saline soil environment was simulated by indoor accelerated test to study the effects of the water-binder ratio and basalt fiber content on the concentration of SO42- in concrete under the variety cycles effects, and a time-varying model of SO42- diffusion coefficient was established based on Fick’s second law. The results show that the sulfate ion concentration at the same depth of the specimen basically increases with the increase of the number of cycles. With the increase of the depth, the SO42- concentration basically decreases firstly and then tends to be stabilized. With the increase of the number of cycles, the depth of SO42- erosion basically increases. Under the same number of cycles, with the decrease of the water-binder ratio, the concentration of SO42- decreases. With the increase of the fiber content, the SO42- concentration basically shows the trend of first decreasing and then increasing. The established time-varying model of SO42- diffusion coefficient of concrete under the action of variety cycles has high accuracy.

摘   要：研究了凝灰岩石粉对粉煤灰低热水泥碾压混凝土的抗压强度、劈裂抗拉强度、轴拉强度、弹性模量、极限拉伸应变的影响，分析了各性能的相关性。结果表明：采用低热水泥单掺粉煤灰或复掺粉煤灰和凝灰岩石粉的胶凝体系可配制出满足要求的碾压混凝土和常态混凝土；单掺粉煤灰的碾压混凝土早期抗压强度、弹性模量、极限拉伸应变基本低于复掺粉煤灰和凝灰岩石粉的碾压混凝土，但后期性能高于复掺粉煤灰和凝灰岩石粉的碾压混凝土；低热水泥混凝土的抗压强度、劈裂抗拉强度、轴拉强度、弹性模量、极限拉伸应变之间均呈正相关关系，并且相关系数均在0.9以上。Abstract: The influence of tuff stone powder on the compressive strength, splitting tensile strength, axial tensile strength, elastic modulus, and ultimate tensile strain of fly ash low heat cement rolled compacted concrete was studied, and the correlation between various properties was analyzed. The results indicate that the combination of low heat cement with fly ash or a combination of fly ash and tuff stone powder can be used to prepare rolled compacted concrete and normal concrete with relatively good performance. The early compressive strength, elastic modulus, and ultimate tensile strain of rolled compacted concrete with single fly ash are basically lower than those of rolled compacted concrete with composite fly ash and tuff stone powder, but higher than those of rolled compacted concrete with composite fly ash and tuff stone powder in the later stage. The compressive strength, splitting tensile strength, axial tensile strength, elastic modulus, and ultimate tensile strain of low heat cement concrete are all positively correlated, and the correlation coefficients are all above 0.9.

摘   要：研究了纳米SiO2在不同温度（0、15、40 ℃）、不同疲劳应力（最大疲劳应力比为0.8、0.9）作用下对水泥沥青砂浆（Cement asphalt mortar，CA砂浆）疲劳强度、疲劳变形、疲劳寿命的影响。结果表明：掺入纳米SiO2可以降低CA砂浆的抗压疲劳变形，有效延缓抗压疲劳变形的发展，提高抗压疲劳寿命；最大疲劳应力比的增加和温度的升高均会加速CA砂浆抗压疲劳变形发展，降低CA砂浆的抗压疲劳寿命；纳米SiO2可以降低CA砂浆疲劳寿命的温度敏感性，有效延缓由温度升高而引起的抗压疲劳损伤加剧趋势。Abstract: The effects of nano-SiO2 on the fatigue strength, fatigue deformation, and fatigue life of cement asphalt mortar (CA mortar) under different temperatures (0, 15, 40 ℃) and fatigue stresses (maximum fatigue stress ratio of 0.8, 0.9) were studied. The results indicate that the addition of nano-SiO2 can reduce the compressive fatigue deformation of CA mortar, effectively delay the development of compressive fatigue deformation, and improve the compressive fatigue life. The increase of maximum fatigue stress ratio and temperature will accelerate the development of compressive fatigue deformation of CA mortar and reduce its compressive fatigue life. Nano-SiO2 can reduce the temperature sensitivity of CA mortar fatigue life, and effectively delay the exacerbation of compressive fatigue damage caused by temperature rise.
