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
Portland cement samples containing amounts of CaCl 2 and NiCl 2 ranging from approximately 1% to 20% by weight have been examined by 29Si and 2~i solid-state MAS NMR as a function of time, and some of the mature pastes have been characterized by X-ray diffraction. Changes in physical properties tha
