· Grinding technique was used in cement produced using clinker, limestone, and fly ash. A type bond ball mill was used to grind cement material. After placing clinker, limestone, and fly ash in the mill, chemicals were added on top of the mix. Cement chemicals with grinding aid and strength enhancing properties were used in dosages of 200 and 800 g/t, respectively. Fly ash, on the other .
Increased durability, dense fly ash concrete helps keep aggressive compounds on the surface. Reduced shrinkage, the lubriing action of flyash concrete reduces water content and drying shrinkage. Reduced heat of hydration, the pozzolanic reaction between fly ash and lime generates less heat, resulting in less thermal cracking when fly ash is used to replace portland cement.
