摘要
利用长余辉材料代替城市夜间灯光照明,可减少城市夜间路灯使用率,美化城市夜间光景,实现建筑的绿色可持续发展。根据建筑行业长余辉材料的制备工艺与应用,采用环氧树脂与水泥材料作为长余辉材料的粘结剂,比较荧光透水混凝土的力学性能与余辉性能。结果表明:相比环氧树脂基,水泥基荧光透水混凝土的施工工艺更简单便捷;单掺6~9 mm粗骨料的基体总体性能最优,抗压强度为25 MPa,透水系数为3.08 mm/s,面层对基体的力学强度影响不大;以荧光粉为主体材料的面层发光效果较好,余辉强度与掺量呈正相关,在掺量为30%时,达到5800 mcd/m^(2),此后的增长效果变缓;发光石面层亮度为4000 mcd/m^(2),并且发光石面层的透水系数较荧光粉面层提升45.28%。比较两者的成本与施工难度,发光石面层工艺更适合实际工程应用。
The use of long afterglow materials instead of urban night lighting,can reduce the use of urban night street lamps,beautify the urban night light scene,and realize the green sustainable development of the building.According to the preparation process and application of long afterglow materials in the construction industry,it uses the two kinds of epoxy resin and cement materials as the binder of long afterglow materials to compare the mechanical properties and afterglow properties of fluorescent permeable concrete.The results show that the construction process of cement-based fluorescent pervious concrete is simpler and more convenient than epoxybased;the overall performance of the matrix with a single blend of 6~9 mm coarse aggregate is optimal,with a compressive strength of 25 MPa and a permeability coefficient of 3.08 mm/s and the top layer had little effect on the mechanical strength of the matrix;the luminescence effect of the surface layer with phosphor as the main material is better,and the afterglow intensity is positively correlated with the doping amount,reaching 5800 mcd/m^(2)when the doping amount is 30%,and the growth effect slows down thereafter;the luminous stone surface layer has a brightness of 4000 mcd/m^(2),and the water permeability coefficient of the luminous stone surface layer is 45.28%higher than that of the phosphor surface layer.Comparing the cost and construction difficulty of the two,the luminous stone surface layer process is more in line with the actual engineering applications.
