Abstract: A superhydrophobic self-luminous concrete material for 3D printing and a method for preparing the same, belonging to the field of building materials. The superhydrophobic self-luminous concrete includes: cement: 1000-1500 parts; quartz sand: 1000-1300 parts; silica fume: 50-100 parts; water: 300-400 parts; water reducing agent: 8-12 parts; cellulose ether: 1-2 parts; defoamer: 2-3 parts; fiber: 4-8 parts; luminous powder: 75-85 parts; reflective powder: 30-45 parts; metakaolin: 15-25 parts; metal filler: 0.015-0.040 parts; and a superhydrophobic coating. By combining 3D printing with the superhydrophobic self-luminous concrete material, the characteristics of energy saving, environment friendliness, high efficiency and low consumption of the 3D printing are highlighted, and the superhydrophobic self-luminous concrete material can be utilized to efficiently prepare fine and special-shaped components.

Abstract: A socket assembled arch rib and an arch bridge including at least one first monomer, the first monomer includes an inner and outer tube snapped outside the inner tube, a first end of the inner tube protrudes from a first end of the outer tube to form a convex part, a second end is located in the outer tube, the outer tube is filled with concrete, and concrete forms a concave part at a second end of the outer tube for socketing the convex part of the other first monomer; for unfilled concrete area inside the CFST structure arch rib, a double-layer CFST monomer with convex and concave parts formed respectively at the end, and the adjacent monomers are connected with each other through the socket-fit of the convex and concave parts, which is convenient for the sub-monomers to fill the concrete in the steel tube, ensuring dense concrete filling.
