Study of aluminum sulfate and anhydrite on cement

And the dosage of AS is the weight percentage of cement both in cement paste and concrete. AS was mixed with cement just before cement paste or concrete were prepared. Cement paste specimens with water to cement ratio (W/C) of 0.4 (by weight) and different dosage of AS were fabricated. For setting time measurement, 2, 4, 6, 8 and 10 % AS were used.

The internal water movement in most gypsiferous soils is normally moderate to rapid, except where gypsum incrusted layers impede the downward movement of water. Mousli (1980) states that hydraulic conductivity of gypsiferous soils in the Meskaneh Plain, Syria, ranges between 0.12 and 1.3 metres per day (m/d); and 1.6 to 8.2 m/d for the surface layers in the Euphrates Basin.
