Alkali-aggregate reaction : presented at the thirty-sixth annual meeting, January 7-11, 1957
Paper 1: Since its publication in 1947, the quick chemical test for alkali reactivity of concrete aggregate has been used by many laboratories. The significance and reliability of the test are evaluated in the light of experience. Paper 2: The magnitude and polarity of the excess ionic charge on various Portland cements has been determined by a procedure which used the silver-ammonia-bromide complex as the indicator ion, and it appears that this ionic charge may be a contributing factor in the swelling and shrinking of hydrated cement. Paper 3: Measurements with a special pressure cell, using an SR-4 strain gage as the sensitive element, show that the alkali-aggregate reaction in cement pastes and mortars may develop pressures in excess of 2,000 PSI.
