The fracture characteristics of crushed limestone sand

1997-11-1  Crushed sand is different in shape, grading, and content of very fine sand (VFS) compared with river sand, and it is well known that the material properties of crushed sand concrete are also different from those of river sand concrete (1-3). However the fracture behavior of crushed sand concrete has been little researched.

A Comparative Study of Concretes Containing Crushed

This paper describes the effects of high temperatures on the strength characteristic of crushed limestone sand concrete (CLSC). To compare, natural (river) sand concrete (NSC) and CLSC specimens were exposed to the three different high temperatures. Visual color-change and weight loss were also carefully examined through the tests. The test results indicated that the decreasing rate of
