Jan 01, 2012 · In this study, the effects of superfine cement on the packing density of cement (directly measured by a wet packing test), the water film thickness of cement paste (taken as the excess water to solid surface area ratio), and the flowability, rheology and strength of cement paste were investigated.
Jan 27, 2017 · In this study, superfine steel slag (FSS) and superfine phosphorus slag (FPS) were ground to 643 and 657 m 2 kg −1, respectively. The water-to-binder (W/B) ratios were set as 0.45 as well as 0.35, and the cement replacements adopted were 15 and 30%. The effects of FSS and FPS on long-term performance and durability of concrete were investigated.
Abstract: Effects of superfine slag powder, fly ash and ultra-fine CaCO3 on compressive strength of sulphoaluminate cement were investigated. Cement hydration products were analyzed by using scanning electron microscopy (SEM). The results show that different fineness and additions of mineral admixture differ in compressive strength.
