This work, a completion of which started in (1), studies the evolution of the mechanical flexural strain of different ranges of mortar samples of 1 X 1 X 6 cm (12 samples/ranges/age/solution) made with sulphoresistant portland cement (P-450-Y, according to RC-75), submerged in filtered drinking water and in the following aggressive solutions: saturated of CaSO4.2 H2O, saturated of CaSO4.2 H2O, of MgSO4.7 H2O (3.22 g/l), of MgSO4.7 H2O (32.2 g/l), saturated of CaSO4.2 H2O plus MgSO4.7 H2O (3.22 g/l) saturated of CaSO4.2 H2O plus MgSO4.7 H2O (32.2 g/l) and artificial ASTM D 1141-75 sea water, during 56 – 90 - 180 - 360 - 540 - 720 - 900 and 1.080 days, after the curing period (1 + 21 days).
It also studies the variation of those mechanical flexural strain and compression strain of 4 X 4 X 16 cm mortar samples (1 : 3), to centrifugal tension of 7 X 7 X 28 cm mortar samples and to flexural strain and compression strain of 10 X 10 X 40 cm concrete samples made with the mentioned cement (P-450-Y), when they are submerged in drinking water and in five agressive solutions (CaSO4.2 H2O saturated solution, Na2SO4 (2.1 g/l) solution, MgSO4.7 H2O (3.22 g/l) solution, Na2SO4 (3.5 g/l) plus NaCl (20.0 g/l) solution and artificial ASTM D 1141-75 sea water during 6 - 12 – 18 – 24 – 30 - 36- 42 - 48 - 54 and 60 months, after the curing period (1 + 30 days).
The results obtained allow to stablish a range of the studied cement according to its behaviour, against the mentioned agressive solutions.
