Effect if $SO_3$ on Clciumsilicate Formation (I)
In this study a Comparative investigation of the effect of $K_2SO_4$ and $CaSO_4$ on the formation of calcium silicate was made. $K_2SO_4$ had little effect on C3S formation. More than 4.0wt% of CaSO4 hindered the reaction of $C_2S$ and CaO so $C_3S$ formation was restrained by forming the reaction rim around $C_2S$ Particles. And activation energy for $C_3S$ formation was calculated around to be 40kcal/mol irespective of the amount of $K_2SO_4$
