Edited by: Elzbutas, H. Kauno Politech. Inst.: Kaunas, USSR. (Russian) 1975. CODEN: 34GFAE. DOCUMENT TYPE: Conference CA Section: 58 (Cement and Concrete Products) The effect of the nature of the nature of original components, additives, impurities, and conditions of firing on the synthesis rate of C3S [12168-85-3], .beta.-C2S [10034-77-2], C3A [12042-78-3], and C4AF [12068-35-8] was studied. The formation rate of .beta.-C2S was faster with Ca(NO3)2.4H2O and SiO2 than with CaCO3 and SiO2. A firing temp. of 1400-1500.degree. was optimum for the synthesis of C3S. Some Cr compds. accelerate the formation of C3S and .beta.-C2S. The synthesis o C3S from C2S was more complete when .gamma.-C2S was used. Fluorides accelerate the mineral formation of C3A and C4AF. .

Quantitative analysis of the compound composition of cement and cement clinker by x-ray diffraction

Quantitative analysis of the compound composition of cement and cement clinker by x-ray diffraction. Knudsen, Torben (Res. Dev. Div., Aalborg Portland, Karlslunde, Den.). Am.Chemicals with cas numbers 10034-77-2 and 12168-85-3 also play role. Ceram. Soc., Bull., 55(12), 1052-4, 1058 (English) 1976. CODEN: ACSBA7. DOCUMENT TYPE: Journal CA Section: 58 (Cement and Concrete Products) Section cross-reference(s): 79 A method for quant. anal. of the compd. compn. of cement and cement clinkers by x-ray diffractometry is described. Compd. compns. from optical point counting of 27 cement clinkers were used for calibration. A vertical-type x-ray diffractometer was used. The Cu target x-ray tube was operated at 50 kv and 32 ma. Integrated intensities from 11 intervals at fixed positions along the 2 .THETA. axis provided the necessary input for computer calcn. of wt. fractions of the four major compds., C2S [10034-77-2], C3S [12168-85-3], C3A [12042-78-3], and C4AF [12068-35-8]. .
