Inthispaper,severaldicalciumsilicates(β-C2S)obtainedfromimpuritieshavebeenstudied.AstudyofthestructureandpropertiesofthesedopeddicalciumsilicatesrevealsthatthedopingwithMgOofBaSO4enhancedtheiractivityandrateofhydration,K20hasasimilareffectroughlesspronounced.Thelatticedistortionandcrystalsizeinβ-dicalciumsilicatesaremeasuredbyX-raypowderdiffractiontechnique,thebindingenergiesof2P3forCaand2PforSiareobtainedbyX-rayphotoelectricspectrum,thevibrationsofthechemicalbondsinsilicateanion[SiO4]4-areexaminedbyFT-IRandLaserRamanspectraandtheheatevolutionduringhydrationreactionforβ-dicalciumsilicatesaredeterminedbymicrocalorimetry.FromtheresultsofXRD,XPS,FT-IR,Ramanandmicro-DSC,therelationshipbetweenthemicrostructureandpropertiesofdopeddicalciumsilicatesandthemechanismofactivationduetoimpuritiesarediscussed.
