Abstract

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.
