Effect of ultrafine mineral powder on the charge passed of the concrete

Abstract The effect of different ultrafine mineral powders (UFMP) and water–binder ratio (W/B) on the charge passed of concrete under 28 days standard curing was investigated in accordance with ASTM C1202-97. The results show that the charge passed of concrete with UFMP is obviously lower than that of the concrete without UFMP, and the order of reducing the charge passed is silica fume (SF)>fly ash (FA)>natural zeolite (NZ)>ground blast furnace slag (GBFS). The charge passed of concrete decreased with W/B reduced and the dosage of the UFMP increased.
