Abstract

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 PbI2. It is revealing to note that, at temperature colder than −5°C, Portland cement is as potent an ice nucleant as is either 2AgI·NaI or PbI₂. At temperatures approaching −5°C, Portland cement alone is effective as nucleant but not the latter two. However, as compared to AgI, its effect is small at all the temperatures considered.
