Paper by FERREIRA GONÇALVES from ISCR 8th 1998 Lisbon Portugal

The paper presents a general principle for the determination of the k-values for fly ash concrete and the results obtained on concretes with cement contents of 200, 300 and 400 kg/rn 3, fly ash cement ratios of 11%, 25%, 43%, 67% and 100% and equal slump of 30 mm. The concrete were tested at 7 days, 28 days, 3 months and 6 111011 his.
