The fracture characteristics of crushed limestone sand ...

The strength of crushed limestone sand concrete was also investigated. It was shown that the fracture energy of concrete was little influenced by the type of fine aggregate. In addition, the fracture energy of crushed sand concrete was slightly higher than that of river sand concrete. This seems to be due to very fine sand (VFS) included in ...

1997-11-1  Silica fume (SF, Elkem Microsilica) was also used to produce high-strength concrete. The crushed sand concrete was made with water-binder ratios of 20, 40, and 60%, and the river sand concrete was made with water-binder ratios of 20, 30, 40, and 60%. Specimen Details and Test Method The size and geometry of the specimen are shown in Figure 3.
