| Summary: | This research work, which will include four publications, was done as a result of the discussions, doubts and controversies which were originated some time ago about the ASTM C 452 method and specially on its 7.0% SO3 content.
To clarify this two portland cements P-1 (14.11% C3A) and P-31 (7.62% C3), all it industriéis, were tested and a pozzolanic cement PUZ-8, by the ASTM C 452-68 method, but using gypsum, CaSO4. 2 H2O, with aggressive contents of 5.0%, 7.0%, 10.0%, 12.0% and 14.0% SO3, respectiverly.
The determined parameters in the correspondent specimens, in this part IA, were ΔL (%) and [ΔL (%)/g. cement].
This first part IA contains the experimental results obtained mainly and the corresponding discussion. As result of this the concept ANSWER of the determined parameter is proposed. |
