✦ Synopsis
A previously postulated hypothesis that concrete or mortar prisms devoid of free Ca(OH)~ will not suffer from alkali-silica expansion has been tested. In this investigation high slag-Portland cements were used to make mortar prisms with a reactive sand. Storage of these prisms in a saturated NaCl bath at 50°C caused no expansion. At the end of the storage period in NaCI bath, the prisms were found to be free of Ca(OH)2. The results are consistent with the proposed hypothesis.
