On the Application of Stone Dust in Low-Grade and Self-Compacting Concrete
Abstract：Much flyash is often added in the preparation of low-grade and self-compacting concrete, playing three kinds of role: replacing a part of cement and thus saving the concrete costs; reducing the hy- dration heat of concrete thus decreasing the volume change and enhancing the anti-cracking action of con- crete. Superfine particles of limestone has early activity, so it can be used as supplementary cementitious material and can replace a part of or all of flyash used in the concrete. This can not only significantly re- duce the concrete costs, but can ensure the other properties of concrete as well.
