Light-transmitting concrete body and preparation method thereof

The invention relates to a concrete material, and discloses a light-transmitting concrete body and a preparation method thereof. The problems that a conventional light-transmitting concrete body is low in overall strength and durability due to the fact that the bonding interface of optical fibers and a cement matrix is fragile and fast in aging are solved. According to key points of the technicalscheme, the light-transmitting concrete body is formed by burying optical fibers into concrete and curing the concrete. The addition amount of the optical fibers accounts for 5-20% of the volume of the light-transmitting concrete body; the optical fibers are pretreated before being buried into concrete; the pretreatment comprises the following steps: Y1, soaking treatment is performed for 1.5-2 hby a 3.5-4.6 wt% of dodecyl benzyl ammonium chloride aqueous solution, the strength of the bonding interface of the optical fibers and a cement matrix is improved, the aging of the optical fibers in the light-transmitting conc
