In his paper Prof. Mehta has commented that the effect of gypsum formation on the sulfate attack has not been properly explained in the literature. As far as I know, Lea was the first to propose that gypsum formation may cause damage to Portland cement concrete and explained this on the assumption o

In regard to the specific value of the strength loss on sulfate attack, the author and his co-workers (6)\* reported 40% loss of compressive strength in 90-day old alite pastes which contained 6% gypsum. It is possible that in the presence of sulfate ions the decrease in the stiffness of C-S-H, whic

In regard to Dr. Chatterji's comments, the author agrees that many investigators including Lea have pointed out the detrimental effect on strength associated with gypsum formation during sulfate attack on portland cement concrete. In the earlier literature, however, the strength loss due to gypsum f

There is considerable current interest (1-4) in magnesia-phosphate cements (MPC), which develop strength rapidly and seem to be ideally suited for repair work. At least three related systems are under investigation, which all involve an acid base reaction between MgO and some compound(s) containing
