The　effect　of　sodium　gluconate(SG)　on　the　corresponding　hydration　process　of　cement　and　regulation　mechanism　was　discussed.　Some　accelerators　such　as　calcium　hydroxide(CH),　aluminum　sulfate(AS)　and　calcium　nitrate(CN)　were　added　into　sodium　gluconate-retarded　cement　paste.　Effect　of　accelerators　on　the　setting　time,　heat　of　hydration,　and　strength　development　of　cement　paste　was　investigated.　The　suppression　mechanism　of　accelerator　for　the　retarding　effect　of　sodium　gluconate　was　discussed,　thus　establishing　a　＇retarding-accelerating＇　system,　which　uses　aluminum　sulfate　and　calcium　nitrate　to　suppress　the　retarding　effect　of　sodium　gluconate.　The　results　show　that　sodium　gluconate　accelerates　the　hydration　of　3CaO•Al2O3(C3A)　and　the　formation　of　entringite(AFt).　Also,　sodium　gluconate　can　control　the　hydration　of　3CaO•SiO2(C3S)　and　the　formation　of　CH　because　of　its　adsorbing　and　complex　action.　On　the　whole,　the　cement　hydration　is　retarded.　The　addition　of　accelerator　breaks　the　dense　protective　film　around　C3S　of　sodium　gluconate-retarded　cement　and　provides　the　crystal　nucleus　for　the　crystallization　of　CH,　thus　promoting　the　hydration　of　sodium　gluconate-retarded　cement.　©　2018,　Editorial　Department　of　Journal　of　the　Chinese　Ceramic　Society.　All　right　reserved.
