Abstract

The diversity of concreting methods in recent years has led to a demand for long retardation of concrete setting. Conventional research has achieved retardation for up to about 3 days by the addition of a set retarder, but few studies have dealt with concrete that is placeable after a much longer period.<br>This paper reports the effects of the set retarder dosage and temperature on the slump, period of set retardation, time limits for superplasiticizing and compressive strength of concrete. The usability of concrete with long-retarded setting is disscussed as well.
