Effect of temperature on the curing of medium-cement refractory concrete with a composite deflocculant

Abstract

Results are presented from studies of the properties of medium-cement refractory concrete with a composite deflocculant (the ratio of sodium tripolyphosphate to polycarboxylate ether Castament FS-20 in the deflocculant was 2/1). The properties are examined as a function of the curing temperature (+10, +20, and +30°C) and the choice of cement (Gorkal 40, Gorkal 70). The effect of curing temperature on the rheology of the paste and the strength of the concrete is also discussed.
