Results are reported on action of 5% solutions of ammonium salts on portland, portland-pozzolana, and high alumina cement concrete; ammonium chloride and nitrate solutions had strong leaching action, acting as dilute acids owing to loss of ammonia by reaction with lime; analysis of specimens showed large reductions in lime content of cements; in action of ammonium sulfate on portland cement, expansion caused by formation of calcium sulfo-aluminate is dominant; high alumina cement was unaffected by ammonium sulfate.
