Abstract
Ammonia gas generated from concrete causes discoloration of objects of art and also becomes a source of contamination of clean rooms which are parts of semiconductor manufacturing facilities. Measures for inhibiting generation of ammonia gas are therefore being called for. It was firstly verified in the study reported here that the ammonia gas generated from concrete originates from nitrogen compounds contained in cement and aggregate. A method of proportioning concrete materials for minimum generation of ammonia gas is proposed based in this finding.
