Influence Of Powder Activated Carbon (Pac) In Fly Ash On The Properties Of Concrete, Zahid Hossain, Sumon Roy Oct 2020

Influence Of Powder Activated Carbon (Pac) In Fly Ash On The Properties Of Concrete, Zahid Hossain, Sumon Roy

Data

Class C Fly Ash (CFA) is commonly used as supplementary cementitious material (SCM) in producing concrete by ready-mix concrete contractors in Arkansas. However, CFA can be used as a partial replacement of Ordinary Portland Cement (OPC) if it meets certain ASTM requirements. It is believed that the presence of powder activated carbon (PAC) in CFA increases the demand of the air-entraining agent (AEA) to achieve specified air content, and this is a concern to transportation agencies such as the Arkansas Department of Transportation (ARDOT) and concrete producers in recent years. Thus, the main goal of this research is to assess …
