In this paper Dr. Litvan seems to be proposing an explanation of the effect of dilute salt solution on cement paste during freezing. At least to some of us, the following points do not seem to be clear. Perhaps Dr. Litvan will comment on these points.
An investigation of the hydration behaviour of ordinary Portland cement clinker in the presence of coal, coke, and charcoal has been carried out. The physico-chemical characteristics of cement are greatly influenced by these materials. The water requirement and setting times are increased. The 1-28
The interface between corroding steel and cement paste containing chloride, with and without condensed silica fume, was studied. For specimens containing only portland cement an interfacial film of large crystals of lime (CH) covered most of the steel surface. Even a 16% replacement of the portland
The reduction in mixing water of the concrete, caused by the addition of a superplasticizer, depends also on the type of cement used. Superplasticizer based on naphthalene sulfonated polymer acts much more effectively on cement containing gypsum dihydrate than on that containing calcium sulfate hemi
