Abstract：

Mercury　intrusion　porosimetry　(called　MIP)　was　used　to　test　the　pore　structure　of　cement　mortar　with　different　water-cement　ratios　at　different　ages.　The　fractal　characteristic　of　the　pore　structure　of　cement　mortar　was　studied,　and　the　pore　surface　fractal　dimension　was　computed　based　on　the　Menger　sponge　model.　The　relations　between　the　fractal　dimension　and　water-cement　ratio,　age,　strength　were　investigated.　The　results　indicated　that,　the　fractal　dimension　was　not　unique　in　the　whole　range　of　pore　size　tested　by　MIP,　and　it　could　be　divided　into　three　regions　by　pore　diameter:　larger　than　100nm,　between　10nm　and　100nm　and　smaller　than　10nm.　The　pore　fractal　characteristic　in　the　regions　of　larger　than　100nm　and　between　10nm　and　100nm　were　remarkable.　The　regular　relations　between　pore　surface　fractal　dimension　and　water-cement　ratio,　age　and　strength　were　obtained.　©　2009　ASCE.
