It is known that concentrated solutions of CaCI 2 can cause the breakdown of Portland cement concrete. Recently it has been shown that the severity of CaC12 attack decreases with increasing temperature and above 40°C concrete is not affected. From the above observation it was inferred that the break

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

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
