Embodiment 1
[0044] A light-transmitting concrete body is formed by embedding optical fibers in concrete and curing the concrete.
[0045] The added amount of optical fiber accounts for 5-20% of the volume of the light-transmitting concrete body.
[0046] Concrete is obtained by mixing raw materials mainly including the following parts by mass:
[0047] 400-429 parts of cement, using P.0.42.5;
[0048] 120-145 parts of water;
[0049] Sand 723-814 parts, using washed river sand with a fineness modulus of 2.3;
[0050] Aggregate 967-1089 parts, using crushed stone aggregate with a particle size of 10-30mm, using multi-stage compounding, in which the particle size is 10mm: 18mm: 30mm, the dosage-mass ratio is 5:3:1;
[0051] Lead slag powder 116-134 parts, fineness modulus 2.0;
[0052] 12-32 parts of sodium polyacrylate;
[0053] Zirconia calcined powder 165-197 parts, particle size 0.8±0.1mm.
[0054] The method for preparing the light-transmitting concrete body includes optical fibe...
Embodiment 7
[0084] A light-transmitting concrete body, which is based on Embodiment 1, the difference is that the optical fiber pretreatment is only processed to Y1, and the optical fiber split obtained by Y1 is fixed in the mold.
Embodiment 8
[0086] A light-transmitting concrete body, which is based on Embodiment 1, with the difference that the distance between the strands of optical fibers is adjusted so that the amount of optical fiber incorporated is 5% of the volume of the light-transmitting concrete body.
