摘要：

This paper reports the results of an investigation on activation of blast furnace slag with the emphasis on achievement of equivalent one-day strength to Portland cement at normal curing temperatures and reasonable workability. The effects of varying dosages of activators NaOH and Na2CO3 are discussed in terms of strength of mini cylinders and also workability by the mini slump method. The results are mainly based on pastes, but comparisons are also made with mortar and concrete results. The effects of preblended gypsum dosage within the slag as well as the effect of ultrafine slag on workability are reported. The results of trials with various water-reducing admixtures and superplastisers and their effects on strength and workability are reported. (C) 1998 Elsevier Science Ltd.
