PREVENTION OF ALKALI-SILICA EXPANSION BY USING SLAG-PORTLAND CEMENT

A previously postulated hypothesis that concrete or mortar prisms devoid of free calcium hydroxide 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 sodium chloride bath at 50 degrees centigrade caused no expansion. At the end of the storage period in the sodium chloride bath, the prisms were found to be free of calcium hydroxide. The results are consistent with the proposed hypothesis. (Author/TRRL)
