The　light　transmitting　cement-based　material　(LTCM)　is　a　kind　of　light　transmitting　new　materials.　A　large　number　of　optical　fiber　was　embedded　in　the　block　and　transfer　light　from　the　light　side　surface　to　the　dark　side.　While　at　present,　the　composition,　structure　and　performance　of　LTCM　have　been　reported　rarely.　The　paper　studied　the　preparation　method,　light　transmitting　property　and　compressive　strength　of　LTCM　with　optical　fiber　embedded　by　means　of　parallel　arrange.　The　results　show　that,　LTCM　gets　higher　light　transmitting　ratio　with　appropriate　optical　fiber　filamentous　by　means　of　parallel　arrange　along　the　light　direction.　This　kind　of　LTCM　can　also　achieve,　even　exceed　the　light　transmitting　ratio　of　the　70g　A4　print　paper　in　the　light　wavelength　range　of　580　similar　to　640nm.　The　light　transmitting　ratio　increases　and　the　compressive　strength　decreases　along　with　the　increase　of　the　optical　fiber　content　in　volume.
