Abstract
Properties of blast furnace slag fine aggregate and compressive strength of concrete using blast furnace slag fine aggregate were studied on following 3 aspects.
1. Properties including of absorption, density, grading and crushed value of blast furnace slag fine aggregate coming from 3 different steel factories and 1 type of natural river sand used as contrast are studied.
2. Properties including of slump, slump flow, air content and density about fresh concrete using blast furnace slag fine aggregate and river sand were tested.
3. Compressive strength of concrete using blast furnace slag fine aggregate was studied. Furthermore, influence of blast furnace slag fine aggregate on compressive strength of concrete was discussed.
