[1069] HYDRATION PROCESS AND DEVELOPMENT OF MECHANICAL PROPERTIES OF EUROPEAN-PRODUCED TYPE I CEMENT
キーワード：compressive strength, elastic modulus, gel/space ratio, Portland cement, Rietveld method, TG-DTA, XRD
Phase composition of cement paste of two different w/c ratios prepared from a European Type I cement was investigated through powder X-ray diffraction and subsequent Rietveld analysis at an early age of the material and the results were confirmed by thermal gravimetric analysis. Furthermore, mechanical properties of the material were measured on cylindrical specimens and based on microstructural properties obtained from the phase composition analysis, a relationship between gel/space ratio and compressive strength was found. Presented results are consistent with previous results of Japanese Portland cement systems.
