This paper presents the results of series of experimental study on the use of fly ash for mass concrete. In laboratory experiment, concrete mixtures with 15 to 40% flyash replacement to Portland cement were tested for workability, strength development with age on cylindrical specimens and temperature rise due to heat of hydration on insulated specimens. In field experiment, concrete mixtures with 15 and 25% fly ash replacement were cast into model walls with thickness of 20cm and 120cm, and were tested for temperature rise, compressive strength on drilled core specimens at the ages of 4, 13 and 65weeks. Carbonation depth were tested at 65 weeks. Effects of fly ash on heat of hydration, temperature rise and strength developmet in massive model walls were discussed.
