应用玻璃质光纤制备透光混凝土的研究

Study on the light transmitting concrete preparation with glassy optical fiber

采用水泥砂浆作为透光混凝土的基体材料,把两种玻璃质多模光纤平行排列在水泥砂浆中,制备出了透光混凝土。考察了光纤体积掺量的变化对透光混凝土材料的透光性能和强度的影响,结果表明:当光纤掺量一定时,芯纤直径较大的光纤使透光混凝土具有较高的透光率,透光率随光纤的掺量增加而增大;抗压强度随光纤掺量的增加而减小,抗折/抗压强度比随光纤的掺量增加而增大。

Two kinds of glassy multimode optical fiber were arranged in parallel in cement mortar as base material to prepare light transmitting concrete light transmitting concrete.Study on the influences of changes in optical fiber volume content to the light transmitting performance and strength of light transmitting concrete showed that, light transmitting concrete got higher light transmitting ratio when using optical fiber with bigger inner core, and the light transmitting ratio of it increased with the increase of optical fiber volume content;the compressive strength decreased and the ratio between flexural strength and compressive strength of light transmitting concrete increased a- long with the increase of the optical fiber content in volume.
