Abstract
Autoclave treatment of concrete bars made from argillaceous dolomitic carbonate aggregates at a temperature of 420 ° ± 3 ° F. and a steam pressure of 295 ± 10 lbs. for 3 to 9 hours caused the progressive development of silicified reaction shells on the coarse carbonate aggregate similar to those found in distressed concrete. Similar treatment of concrete bars made from pure limestone aggregates induced no reaction shell growth. The susceptibility of carbonate aggregates to silicification could be rapidly determined by the autoclave method.
