The trimethylsilyl derivatives of the silicate fractions of three fully hydrated Portland cement pastes have been studied by gas-liquid and gel-permeation chromatography. The pastes had 9-II% of the silica as monomer, 22-30% as dimer and 44-57% as polysilicate. Gel-permeation chromatograms of the po
