In　this　paper,　an　efficient　naphthalene　superplasticizer　is　obtained　by　improving　the　production　process,　shortening　the　production　cycle.　Considering　the　performance　and　production　costs　of　the　water-reducing　agent,　the　optimized　mixture　ratio　was　obtained　by　mixing　the　product　with　different　kinds　of　compound　retarder.　Meanwhile,　the　cement　paste　fluidity　of　the　complex　product　in　different　time,　cement,　water-cement　ratio　and　superplasticizer　content　was　also　determined　to　be　compared　with　the　commercially　available　superplasticizer　and　characterized　performance　of　naphthalene　compound　water-reducing　agent.　The　results　showed　that　the　optimal　mass　ratio　of　naphthalene　superplasticizer,　sodium　gluconate,　sodium　tripolyphosphate　and　lignin　sulfonate　is　10.0420.0420.305.　The　cement　paste　fluidity　of　the　self-made　naphthalene　superplasticizer　mixture　prevails　over　the　commercially　available　superplasticizer.　©　2011　IEEE.
