It has been shown that expansion of mortar prisms, due to alkali-silica reaction, can be quantitatively related to their environment, i.e. alkali ion concentration and temperature by an equation of the type The physical significance of negative signs of dl/dC and dl/dT terms have been discussed.

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 ba

From an extensive petrographic investigation of concrete samples suffering from alkali-silica reaction, it has been hypothesized that a deliberately introduced air-bubble system will reduce expansion due to alkali-silica reaction. The above hypothesis has been tested using mortar bars made from 35 s
