Abstract: This paper evaluates the use of water, superplasticiser and cement slurry as retempering agents for plain and superplasticised concretes. Water, the most economical retempering agent, produces significant loss in strength of concrete particularly for the superplasticised concrete. Cement slurry, although producing restoration of slump with no significant effect on strength, results in less workable concrete mix due to stickiness effect from the high cement content. Superplasticiser, despite its cost and influence of increasing the rate of slump loss, is the best retempering agent with any loss in strength. © 1985.
