Compressive strength and elastic modulus data are presented for four concrete mixtures with ratios (by volume) of Class C fly ash to total cementitious materials (portland cement plus fly ash) varying from 0.25 to 0.50. Data were collected at times ranging from 1 1/2 hours past time of final set to 14 days. These data are plotted versus the logarithm of time and in the modulus of elasticity-square root of compressive strength plane.
