In this study class F calcium fly ash was converted into nano size in a ball grinding mill and its size was confirmed by SEM analysis. It was found that concrete with cement replaced with 23% nano fly ash gave 34% more compressive strength, % more tensile strength and % more flexural strength than the normal cement concrete.

A total of ten mixes, including the control mix, were produced. Quantities of the concrete ingredients were calculated by adopting the standard procedure of ACI 211 [48] to achieve a 28days cylinder strength of 21 MPa and slump range of 5075 mm. The calculated OPC content for the control mix was replaced with SCM in ratios of 15 %, 25 %, and 35 % by weight.

This study presents the performance of quarry rock dust (QRD) incorporated fly ash (FA) and slag (SG) based geopolymer concretes (QFSGPC) exposed to ambient and elevated temperatures. A total of five QFSGPC mix types were prepared. The quantity of FA (50%) was kept constant in all the mixes, and SG was replaced by 5%, 10%, 15%, and 20% of QRD. The fresh, hardened properties of the QFSGPC ...

ground separately. The mass of the ash sample was 100 g per grinding, the speed of the ball mill was 300 r/min, and the variable condition was the grinding time. After the grinding, the ash sample was sieved through a sieve with a pore diameter of mm, and the ash sample under the sieve was tested and used as a cement mixing material.
