FLYASH CAN IMPROVE THE PERFORMANCE OF CONCRETE STRUCTURES IN THE ARABIAN GULF . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.
The effects of dry (23 degrees C, 40% RH (relative humidity)) and hot-dry (45 degrees C, 20% RH) exposure conditions on the strength development, pore size distribution, water sorptivity and hydroxide ion concentration of the hydrated cement paste and concretes, with and without flyash, are presented. The specimens were cured in fog room for 0, 1 and 7 days before exposure to the two regimes. The results indicate that given adequate prior curing of 7 days, the strength, strength development and water sorptivity characteristics of cement paste and concretes with flyash are superior to those without flyash, both in dry and hot-dry exposure conditions. It is concluded that flyash concretes can be used in the Arabian Gulf like ambient conditions with added benefits provided some minimum curing can be guaranteed.(A) For the covering abstract of the conference see IRRD 828897.
