摘   要：将搅拌站废浆经清洗、烘干、研磨后制成废浆颗粒，研究了废浆颗粒掺量（0、2.5%、5.0%、7.5%、10.0%，等质量取代河砂）对砂浆稠度和抗压强度的影响，并分析了微观结构。结果表明：废浆颗粒的掺入降低了砂浆稠度，提高了砂浆3 d、28 d抗压强度；适量废浆颗粒的掺入在一定程度上提高了砂浆基体的密实度；综合考虑砂浆的工作性和抗压强度，建议废浆颗粒的最佳掺量为5.0%。 Abstract: Waste slurry in mixing station was processed into particles through washing, drying, and grinding, and the effects of content of waste slurry particles(0, 2.5%, 5.0%, 7.5%, 10.0%, replacing river sand by equal mass) on the consistency and compressive strength of mortar were investigated, along with microstructural analysis. The results show that the incorporation of waste slurry particles reduces the consistency as well as increases the 3 d and 28 d compressive strength of the mortar. The incorporation of appropriate content of waste slurry particles improves compactness of the mortar matrix to some extent. Considering the workability and compressive strength of mortar, the optimal content of waste slurry particles is recommended to be 5.0%.

摘   要：制备了碱激发煤气化粗渣（CCGS）-细磨高炉矿渣（GGBS）混凝土砖和碱激发CCGS-GGBS-水洗机制砂滤泥（WMS）混凝土砖，研究了CCGS取代率（0、30%、50%、70%、100%）和WMS取代率（0、10%、20%、30%、40%、50%）分别对碱激发CCGS-GGBS混凝土砖和碱激发CCGS-GGBS-WMS混凝土砖体积密度、吸水率、抗折强度、抗压强度和孔隙率的影响。结果表明：随着CCGS取代率的增加，混凝土砖的密实度降低，吸水率和孔隙率增大，体积密度、抗折和抗压强度降低；随着WMS取代率的增加，混凝土砖的流动度和体积密度降低，抗折和抗压强度均先增后降，吸水率和孔隙率均先降后增；当CCGS取代率为50%、WMS取代率为10%时，混凝土砖的体积密度、吸水率满足相关标准中的B级密度等级要求，抗压强度满足MU15强度等级要求。 Abstract: Alkali-activated coarse coal gasification slag(CCGS)-ground granulated blast furnace slag(GGBS) concrete bricks and alkali-activated CCGS-GGBS-water-washed manufactured sand filter mud(WMS) concrete bricks were prepared, and the effects of substitution rates(0, 30%, 50%, 70%, and 100%) of CCGS and the substitution rates(0, 10%, 20%, 30%, 40%, and 50%) of WMS on the bulk density, water absorption rate, flexural strength, compressive strength, and porosity of alkali-activated CCGS-GGBS concrete bricks and alkali-activated CCGS-GGBS-WMS concrete bricks were investigated, respectively. The results show that, as the substitution rate of CCGS increases, the compactness of concrete bricks decreases, the water absorption rate and porosity increase, and the bulk density, flexural and compressive strengths decrease. As the substitution rate of WMS increases, the fluidity and bulk density of concrete bricks decrease, the flexural and compressive strengths both first increase and then decrease, and the water absorption rate and porosity both first decrease and then increase. When the substitution rate of CCGS is 50% and the substitution rate of WMS is 10%, the bulk density and water absorption rate of the concrete bricks satisfy the requirements of the B density grade, and compressive strength satisfies the requirement of the MU15 strength grade in the relevant standards.

摘   要：测试了不同煅烧温度（600、700、800 ℃）下污泥灰的化学成分、矿物组成和粒径分布，研究了污泥灰的煅烧温度和掺量（0、3%、5%、7%、9%、11%）对胶凝材料标准稠度用水量、凝结时间及砂浆干燥收缩性能和力学性能的影响。结果表明：污泥灰具有潜在的火山灰活性，适当提高污泥灰煅烧温度能有效提升其可磨性；随着煅烧温度的升高或污泥灰掺量的增加，胶凝材料标准稠度用水量基本增大；当煅烧温度为600 ℃、700 ℃时，随着污泥灰掺量的增加，胶凝材料的初、终凝时间基本延长，当煅烧温度为800 ℃时，随着污泥灰掺量的增加，胶凝材的初、终凝时间均先延长后缩短；当污泥灰煅烧温度为700 ℃、掺量为5%时，砂浆试件的干燥收缩性能和力学性能相对较好。 Abstract: The chemical compositions, mineral compositions and particle size distribution of sludge ash were tested under different calcination temperatures(600, 700, 800 ℃), and the effects of calcination temperature and content(0, 3%, 5%, 7%, 9% and 11%) of sludge ash on the standard consistency water consumption and setting time of cementitious materials, as well as on the drying shrinkage property and mechanical properties of mortar were investigated. The results show that sludge ash has potential pozzolanic activity, and appropriately increasing the calcination temperature of sludge ash can effectively improve its grindability. With the increase of calcination temperature or the content of sludge ash, the standard consistency water consumption of cementitious materials basically increases. When the calcination temperature is 600 ℃ and 700 ℃, with the increase of the content of sludge ash, the initial and final setting time of cementitious materials basically prolong. When the calcination temperature is 800 ℃, with the increase of the content of sludge ash, the initial and final setting times of cementitious materials first prolong and then shorten. When the calcination temperature of sludge ash is 700 ℃ and the content is 5%, the drying shrinkage property and mechanical properties of the mortar specimen are relatively good.

摘   要：采用生活垃圾焚烧炉渣和矿渣制备了低碳复合胶凝材料，研究了m炉渣∶m矿渣（2∶8、3∶7、4∶6、5∶5、6∶4、7∶3）对其活性指数的影响。在此基础上，研究了低碳复合胶凝材料掺量（0~60%）对混凝土力学及耐久性能的影响。结果表明：当m炉渣∶m矿渣不超过4∶6时，低碳复合胶凝材料的28 d活性指数大于95%；当m炉渣∶m矿渣为4∶6时，随着低碳复合胶凝材料掺量的增加，混凝土的28 d抗压强度呈先减小后略微增大的趋势；掺入适量低碳复合胶凝材料可使混凝土具有较好的抗氯离子渗透、抗冻和抗碳化性能。 Abstract: Low-carbon composite cementitious materials were prepared by using municipal waste incineration bottom ash and slag, and the effect of mbottom ash ∶ mslag(2∶8, 3∶7, 4∶6, 5∶5, 6∶4, 7∶3) on the activity index of low-carbon composite cementitious materials was studied. Furthermore, the influence of the content (0~60%) of low-carbon composite cementitious materials on the mechanical properties and durability of concrete was studied. The results show that when the mbottom ash ∶ mslag does not exceed 4∶6, the 28 d activity index of low-carbon composite cementitious materials is greater than 95%. Under the condition of mbottom ash ∶ mslag of 4∶6, with the increase of the content of low-carbon composite cementitious materials, the 28 d compressive strength of concrete shows a trend of first decreasing and then slightly increasing. Adding an appropriate content of low-carbon composite cementitious materials can make concrete have good resistance to chloride ion penetration, frost resistance, and carbonation resistance.

摘   要：研究了再生微粉与赤泥复掺比例（4∶0、3∶1、2∶2、1∶3、0∶4）对生态混凝土工作性、孔隙率、抗压强度和抗硫酸盐侵蚀性能的影响。结果表明：随着赤泥比例的增加，净浆的流动度降低，生态混凝土的总孔隙率、连通孔隙率、28 d抗压强度均先增大后降低；再生微粉与赤泥复掺降低了生态混凝土的抗硫酸盐侵蚀性能；综合考虑生态混凝土的各项性能，推荐再生微粉与赤泥的复掺比例为3∶1。 Abstract: The effects of the compound ratios(4∶0, 3∶1, 2∶2, 1∶3, 0∶4) of recycled micro powder and red mud on the workability, porosity, compressive strength and sulfate resistance of ecological concrete were investigated. The results show that with the increase of the proportion of red mud, the fluidity of the slurry decreases, the total porosity, the connected porosity, and the 28 d compressive strength of the ecological concrete first increase and then decrease. The compound mixing of recycled micro powder and red mud reduces the sulfate resistance of ecological concrete. Comprehensive consideration of the performance of ecological concrete, the recommended compound ratio of recycled micro powder and red mud is 3∶1.
