Influence of Chemical Admixtures on Fresh and Hardened Properties of Prolonged Mixed Concrete

Figure 2

Slump test results of RM, M1, M2, and M3 mixtures (W/C = 0.40, s/a = 0.40, and C = 340 kg/m³): (a) M1 = average dosage of admixture, RM = no admixture; (b) M2 = maximum dosage of admixture, RM = no admixture; (c) M3 = maximum dosage of admixture in two stages, RM = no admixture.
