Light　transmitting　cement-based　material　(LTCM)　was　prepared　by　polymethylmethacrylate　(PMMA)　fibers,　Portland　cement,　aggregates,　deforming　agent　and　water　reducers　in　a　given　proportion.　The　compressive　and　flexural　strengths　of　LTCM　prepared　with　different　diameters　and　volume　fractions　of　optical　fibers　were　measured　at　the　age　of　28　d.　The　compressive　and　flexural　strengths　of　LTCM　specimens　decreased　with　an　increasing　volume　fraction　of　fiber.　Factors　such　as　distance　from　the　light　source　to　specimen,　diameter　and　volume　fraction　of　fiber,　and　the　variety　of　light　sources　that　affect　the　optical　power　of　LTCM　were　studied　in　this　paper.　The　experimental　results　demonstrate　that　the　optical　power　was　significantly　affected　by　the　distance　from　light　source　and　specimen,　and　the　diameter　and　number　of　fibers.　The　matrix　material,　cross　section　of　optical　fiber,　and　the　interface　between　fiber　and　matrix　were　analyzed　by　SEM.　(C)　2015　Elsevier　Ltd.　All　rights　reserved.
