Portland cement was studied for its nucleating ability by the freezing behaviour exhibited of drops produced from aqueous suspension of Portland cement vis-a-vis of drops produced from suspensions of AgI, 2AgI.NaI and PbI,. I t is revealing to note that, at temperature colder than 5"C, Portland cement is as potent an ice nucleant as is either 2AgIaNaI or PbI,. At temperatures approaching 5"C, Portland cement alone is effective as nucleant but not the latter two. However, 8s compared to AgI, its effect is small at all the temperatures considered.
