摘要：为研究废陶瓷对混凝土力学性能的影响，选取了六种不同状态的废陶瓷以0、45%、50%、55%、60%、65%、70%、75%、100%的取代率等质量替换天然石子，共制作了294个废陶瓷混凝土抗压试件和抗折试件，养护28 d后分别测试其抗压强度和抗折强度。通过对试验数据的分析，研究了不同废陶瓷取代率对混凝土抗压强度和抗折强度的影响，并运用回归分析方法建立了不同废陶瓷取代率下废陶瓷混凝土抗压强度和抗折强度的预测公式。 Abstract: In order to study the effect of waste ceramics on the mechanical properties of concrete, a systematic study was conducted to replace natural stones with mass such as 0, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 100% replacement rate. Six kinds of waste ceramics in different states were selected to make a total of 294 standard compressive and standard flexural specimens of waste ceramic concrete. After curing for 28 days, the standard compressive strength and flexural strength were tested respectively. Based on the analysis of experimental data, the effects of different replacement rates of waste ceramics on the standard compressive strength and flexural strength were studied. The regression analysis method is used to establish the prediction formula of the standard compressive strength and flexural strength of the waste ceramic concrete with different replacement rates.

摘要：为探索建筑垃圾再生微粉用作掺合料的可行性，制备了三种细度的废砖、废混凝土再生微粉，测试其物化性质，并研究不同组成、细度、掺量的再生微粉对水泥胶砂性能的影响。结果表明，组成对水泥胶砂性能影响不大，细度和掺量有较大影响；Ⅱ级再生微粉工作性较好、强度较高；掺量在20%以内对胶砂流动性的降低并不明显，且抗压、抗折强度比分别在85%、75%以上。 Abstract: In order to explore the feasibility of using recycled powder as admixture，waste bricks and waste concrete recycled powder were prepared in three kinds of fineness. The physicochemical properties were tested and the effects of different compositions, fineness and dosage of recycled powder on the performance of cement mortar were studied. The results show that the composition has little effect on the performance of cement mortar, and the fineness and dosage has great influence. The grade II recycled powder has better working performance and higher strength; the reduction of the fluidity of the mortar within 20% is not obvious, and the compressive and flexural strength ratios are above 85% and 75% respectively.

摘要：为定量研究玻化微珠砂浆在搅拌过程中骨料分布均匀性受搅拌条件的影响，对新拌玻化微珠砂浆中的骨料进行分离，并根据分离得到的骨料与砂浆质量占比，定义了评价新拌砂浆中骨料分布均匀性的均匀度指数。试验结果表明：新拌砂浆中骨料分布均匀性随搅拌时间的延长呈先优化后劣化的变化趋势，搅拌过程中存在最优均匀度；卧式与立式搅拌机均在搅拌至4 min时达到最佳均匀度，卧式搅拌机的新拌砂浆中骨料分布均匀度优于立式搅拌机；玻化微珠骨料参与搅拌的时间相同时，采用先搅拌后投入玻化微珠骨料的方式能够优化骨料分布的均匀性。更高的搅拌机转速能更快提升新拌玻化微珠砂浆均匀度，但是较低的搅拌机转速下拌和的新拌玻化微珠砂浆极限均匀度更优，达到极限的耗时更长。 Abstract: In order to quantitatively study the uniformity of aggregate distribution during the stirring process of glazed hollow bead mortar, the aggregate of the fresh glazed hollow bead mortar was separated. According to the mass ratio of aggregate and mortar obtained by separation, the uniformity index for evaluating the uniformity of aggregate distribution in fresh mortar is defined. The test results show that the uniformity of aggregate distribution in fresh mortar is firstly optimized and then deteriorated with the extension of stirring time, and the optimum uniformity exists during the mixing process. Both horizontal and vertical mixers achieve optimum uniformity when stirred for 4 minutes. The uniformity of aggregate distribution in the new mortar of the horizontal mixer is better than that of the vertical mixer; when the glazed hollow bead aggregates participate in the same stirring time, the uniformity of aggregate distribution can be optimized by first mixing and then feeding into vitrified microbead aggregates. Higher mixer speeds can increase the uniformity of fresh glazed hollow bead mortar faster, but the fresh glazed hollow bead mortar blended at lower mixer speeds has better uniformity and longer time to limit.
