Freeze-thaw durability of high strength silica fume concrete
Specimens from 27 batches of concrete with water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability in accordance with ASTM C666, procedure A (freezing and thawing in water). In addition, another set of similar …

The fracture toughness of silica fume concrete using experimental and numerical techniques
… materials. One such material is condensed silica fume (CSF) which is an industrial by-product and until recently was discarded as waste. Research has shown that the addition of CSF to concrete can have the dual benefits of increased strength and improved durability.<br/>In the present study …

Abrasion resistance of concrete and the use of high performance concrete for concrete railway crossties
… project focused on the abrasion resistance of concrete railway crossties. In the first phase of this project, a series of high performance concrete mixes was developed that utilized different replacement levels of portland cement by silica fume (3%, 7% and 15%), class F fly ash (18%) and slag …
