Research on the use of fly ash to make reactive powder concrete
Abstract
Reactive powder concrete is a type of concrete using materials with fine grains and high activity that can participate in chemical reactions in hydration process. Reactive powder concrete has a high compressive strength, usually greater than 100 MPa. However, such materialutilized in applicationsmust also go through selection and must be of good quality, i.e. high activity and fineness, and loss when heated. In this study, the use of locally available untreated raw materials such as natural sand, fly ash partially replacing cement for the fabrication of reactive powder concrete with a minimum strength requirement is examined and proposed.
