Alkali-aggregate Reactions. Some aggregates containing reactive silica will react with the alkalies in cement-sodium and potassium oxides-to form an alkali-silica gel which takes up water and swells. This causes abnormal expansion and map-cracking of the concrete.ome aggregates containing reactive silica will react with the alkalies in cement-sodium and potassium oxides-to form an alkali-silica gel which takes up water and swells.

Lomustine and prednisone are both a bit immunosuppressive. She may just have a urinary tract infection. UTI's can be brought on by stress, such as being boarded. It may take her a bit longer to get over the infection due to the Lomustine, prednisone and the lymphoma.
Hi-I took prednisone for hives & sinus infections twice for apx. 2 week periods within less than 3 months. With the 1st round I started menstruationg again (am 48 perimenopausal & hadn`t had one for 6 months). Within a couple of weeks off the 2nd round I started having extremely dry skin. I normally have always had oily skin, but now it is dry-legs are so bad the skin peels like a sunburn.My arms look like an alligator!!
