摘要：利用含红砖的再生细骨料100%替代天然砂，制备生态干混砂浆，研究了用水量、再生粉料掺量和外加剂掺量对干混砂浆力学性能的影响。结果表明：当再生粉料和外加剂掺量不变时，砂浆强度随着用水量的增大而降低，但56 d强度增长率反而增大；当再生粉料掺量和用水量不变时，外加剂掺量的增加对砂浆各龄期的强度均有负面影响；当外加剂掺量和用水量不变时，再生粉料掺量为20%时，对应的砂浆强度最大，低于或高于此掺量均会使砂浆强度降低；含红砖再生细骨料干混砂浆的后期强度（56 d）仍有较大提升空间。 Abstract: The dry mixed mortar was prepared with 100% recycled fine aggregate containing crushed red brick instead of natural sand. The effects of different water addition, recycled powder content and admixture content on the mechanical properties of dry mixed mortar were studied. The results show that when the recycled powder content and admixture content are constant, the strength of the mortar decreases with the increase of water addition, while the growth rate of 56 d strength increases. When the recycled powder content and the water addition remain unchanged, the increase of admixture content has a negative impact on the strength of the mortar at all ages. When the admixture content and the water addition remain unchanged, the mortar with 20% recycled powder has the highest strength, and the strength of the mortar is reduced when the content is lower or higher than 20%. There is still a large increase space in the late strength (56 d) of dry mixed mortar with red brick recycled fine aggregate.

摘要：研究了再生粗骨料替代率和骨料包浆对自密实再生混凝土力学性能和抗氯离子渗透性的影响。结果表明：当再生粗骨料替代率分别为30%、60%、100%时，与未包浆再生骨料混凝土相比，预包浆再生骨料混凝土的坍落扩展度分别提高了0.76%、3.33%、5.17%，抗压强度分别提高了5.9%、3.2%、6.1%，劈裂抗拉强度分别提高了5.2%、11.2%、18.2%；随着再生粗骨料替代率的增加，混凝土的电通量值增大，当再生粗骨料替代率分别为30%、60%、100%时，与未包浆再生骨料混凝土相比，预包浆再生骨料混凝土的电通量值分别下降了16.7%、22.9%、8.6%；骨料经过包浆处理后，改善了自密实再生混凝土的力学性能及抗氯离子渗透性。 Abstract: The effects of recycled coarse aggregate replacement rate and aggregate grouting on the mechanical properties and resistance to chloride ion permeability of self-compact recycled concrete were studied. The results show that when the replacement rates of recycled coarse aggregate are 30%, 60% and 100%, compared with the ungrouted concrete, the slump-flow expansion of the grouted concrete are increased respectively by 0.76%, 3.33% and 5.17%, the compressive strength of the grouted concrete are increased respectively by 5.9%, 3.2% and 6.1%, the split tensile strength of the grouted concrete are increased respectively by 5.2%, 11.2% and 18.2%. With the increase of replacement rate of recycled coarse aggregate, the concrete electric flux value increases. When the replacement rates of recycled coarse aggregate are 30%, 60% and 100%, the electric flux values of the grouted recycled concrete decrease respectively by 16.7%, 22.9% and 8.6% compared with ungrouted concrete. The mechanical properties and resistance to chloride ion permeability of the self-compacting recycled concrete are improved after the aggregates are grouted.

摘要：在已有试验基础上，进行了基于内聚力模型的密肋复合墙板静力加载全过程有限元分析，研究了密肋复合墙板结构在粮食侧压力作用下的受力机理。结果表明：黏结界面开裂后，基于内聚力模型的密肋复合墙板在协同受力作用下表现出“拱”破坏形式；黏结界面损伤主要分布在跨中板底及板顶与边肋梁、柱接触区域，损伤及位移模拟结果与试验结果一致；基于内聚力模型的密肋复合墙板具有与矩形双向板相似的塑性铰线破坏特征，验证了内聚力模型的合理性，为粮食平房仓密肋复合墙板的结构计算分析提供了参考。 Abstract: On the basis of the existing tests, the finite element analysis of the whole process of static loading of multi-ribbed composite wall was carried out based on the cohesion model, and the mechanical mechanism and the finite element calculation method of multi-ribbed composite wall structure under the lateral pressure of grain were studied. The results show that after the interface cracks, the ribbed composite wall based on cohesion model shows “arch” failure mode under the synergistic force. The damage of the bond interface is mainly distributed in the area between the bottom and top of the mid-span plate with the side rib-beam and rib-column. Based on the cohesive model, the multi-ribbed composite wall has similar failure characteristics of yield line to the rectangular two-way plate, which verifies the rationality of the cohesive model, and provides a reference for the calculation and analysis of the multi-ribbed composite wall board structure in storehouse.

摘要：研究了纳米SiO2对污泥焚烧灰-水泥复合胶凝体系性能的影响，并对其水化程度进行了分析。结果表明：随着污泥焚烧灰掺量的增加，复合胶凝体系的标准稠度用水量增加、凝结时间延长，水泥胶砂流动度降低、抗压和抗折强度降低；纳米SiO2的掺入在一定程度上缩短了复合胶凝体系的凝结时间，提高了水泥胶砂的强度，但对工作性不利；掺入纳米SiO2后，复合胶凝体系7 d内的化学结合水生成量和生成速率较高，纳米SiO2对复合胶凝体系早期水化影响较大。 Abstract: The influence of nano-SiO2 on the performance of sludge incineration ash-cement composite cementitious system was studied, and its hydration degree was analyzed. The results show that with the increase of sludge incineration ash content, the standard consistency water requirement of the composite cementitious system increases, the setting time is prolonged, the fluidity of the cement mortar decreases, and the compressive and flexural strengths decrease. The incorporation of nano-SiO2 shortens the setting time of the composite cementitious system to a certain extent and improves the strength of cement mortar, but it is not good for workability. After adding nano-SiO2, the amount of chemically bound water and the rate of formation within 7 days of the composite cementitious system are higher, which shows that nano-SiO2 has a great influence on the early hydration of the composite cementitious system.

摘要：采用固定水胶比和固定流动度两种方案进行对比试验，研究了不同掺量的玄武岩纤维对复合磷酸镁水泥（MPC）砂浆流动度和力学性能的影响，并采用扫描电子显微镜（SEM）观察了微观形貌。结果表明：在固定水胶比的情况下，随着玄武岩纤维掺量的增加，MPC砂浆的流动度降低，但力学性能有所提高，且掺量为3.5 kg/m3时，力学性能最优，超过此掺量则增幅下降；在固定流动度而水胶比随纤维掺量增加而增大的情况下，MPC砂浆的力学性能整体呈下降趋势；SEM结果表明，在一定掺量范围内，玄武岩纤维在MPC砂浆中分散均匀，掺量过多则会产生纤维团聚现象；MPC砂浆与玄武岩纤维之间有一定的黏接力和摩擦力，但二者的黏结性或相容性不足；MPC砂浆的水化过程不会对玄武岩纤维造成损伤。 Abstract： The comparative tests were carried out with two schemes of fixed water-binder ratio and fixed fluidity, and the effect of different content of basalt fiber on the fluidity and mechanical properties of composite magnesium phosphate cement (MPC) mortar was studied, and the scanning electron microscope (SEM) was used to observe its microscopic appearance. The results show that under the condition of fixed water-binder ratio, the fluidity of MPC mortar decreases but its mechanical properties improve with the increase of basalt fiber content, and the mechanical properties are optimal when the content is 3.5 kg/m3, but the increase decreases when the content exceeds 3.5 kg/m3. When the fluidity is fixed and the water-binder ratio increases with the increase of fiber content, the overall mechanical properties of MPC mortar tend to decline. The SEM results show that within a certain content range, basalt fiber is evenly dispersed in MPC mortar, while over-mixing will produce fiber cluster phenomenon. MPC mortar and basalt fiber have certain adhesion and friction force, but the adhesion or compatibility is insufficient. The hydration process of MPC mortar will not cause damage to basalt fiber.
