Fly ash (FA) has long been the most accepted pozzolanic material for substituting cement in concrete. In typical applications, replacing up to 20 % of the cementitious material mass with fly ash can enhance concrete's physical and mechanical properties [8, 15, 16].Utilizing fly ash, a by-product of industrial processes, has appeared to address sustainability concerns in …

This paper reports on the use of Ultra-Fine Fly Ash (UFFA) used as up to 50% partial replacement for cement in concrete. UFFA is a new generation fine coal fly ash, which is double-classified to obtain the finer particles from the classified bulk. The influence of UFFA on fresh properties (flow, setting time and air content), porosity of mid to ...

However, in the ultra-fine grinding process, the grinding technique and the physical and chemical properties of the abrasive are an important determining factor [10], these methods that were used to crush FA have poor efficiency or high energy consumption. Therefore, finding a low-energy loss comminution and efficient method for the practical ...

One commonly used pre-treatment process is mechanical grinding, which activates FA and produces a finer version known as ultra-fine fly ash (RUFA) [30], [31]. RUFA has smaller particle size and larger specific surface area compared to FA, with approximately double the specific surface area. Additionally, RUFA exhibits higher reactivity due to ...

In recent decades, manufacturers have begun processing conventional fly ash to produce reactive ultra-fine fly ash (RUFA) for the construction industry [23]. Micro-spheres burst when heated to 260 °C, the shells begin splintering at approximately 1100 °C, and they collapse entirely at roughly 1300 °C by the particle separation process [24,25].
