Title: Pulverized Fuel Ash Cement Activated by Nanographite

Abstract:Advancements of early-age physical properties are examined for the pulverized fly ash (pfa) cement system blended with nanographite (nG) in this study. Class F fly ash (FFA), nG, and ASTM Type I cement are used to prepare various cement combinations (for example, 35% FFA + 65% ASTM I + 1.1% nG). Pastes and mortars are mixed with these cements with tap water or with tap water + superplasticizer (SP) to monitor developments on physical properties of the FFA-cement. According to present standards, experimented properties are water absorption, calcium hydroxide content, setting time, flow, flexural strength, and compressive strength for the FFA-cement (FFA-C), FFA-C/nG combinations, pure cement, and PC/nG combinations. It is concluded from the research results that FFA-C activated nG is favorable in terms of water absorption, Ca(OH)2 content, setting time, flow, and strength gain when compared to pure cement and nG-blended cement.
