    Conduction calorimetric studies of ternary binders based on Portland cement, calcium aluminate cement and calcium sulphate

    Different binders of Portland cement, calcium aluminate cement and calcium sulphate (PC/CAC/C ¯S) have been investigated to determinate the influence the CAC and C ¯S amount in the reactions mechanism. Several mixtures were studied, ratios of 100, 85/15 and 75/25 of PC/CAC with 0, 3 and 5 % of C ¯S . Conduction calorimetric technique was used to follow the hydration during 100 h. The XRD and FTIR techniques were used as support in the analysis of the hydration products. The results have shown that the studied ternary systems form an extra amount of ettringite, and changes in the reactions mechanism with respect to a PC. The reactions mechanism depends on the CAC and C ¯S amount present in the different binders.
