Polyvinyl　alcohol　fiber　(vinylon　fiber)　was　mixed　with　cementing　material　(cement,　fly　ash　and　volatilized　silica),　milled　and　dispersed　for　40　minutes　through　ball-miller,　and　then　mixed　with　fine　aggregate　(quartz　sand)　to　get　motar.　The　properties　of　motar　were　discussed　according　to　relative　standards　of　motar.　The　results　show　that　the　tensile　strength　and　bending　strength　of　motar　with　ball-milled　fiber　increase　distinctively,　especially　for　tensile　strength　with　age　(increased　40.8%　for　90　d)　while　fluidity　and　compressive　strength　of　the　motar　has　a　little　change.　So　the　cement　with　milled　fiber　can　increase　mechanics　properties　and　has　little　effect　on　operation　properties.　SEM　shows　that　milled　fiber＇s　surface　become　rough,　so　as　to　improve　the　grasp　ability.　The　research　hopes　to　provide　a　new　method　for　fibers　to　mix　in　cement-matrix　material.　Fiber　would　be　mixed　in　milling　process　of　cement　manufacture　and　a　kind　of　fiber-cement　would　be　produced.
