What are the effects of silica flour in portland cement and what is the best ratio?
Hydrated Portland cement undergoes a slow phase transition above 230°F in which the calcium silicate hydrate (CSH) gel phase reacts with calcium hydroxide and is transformed into crystalline dicalcium silicate hydrate (α-C2SH) which is much weaker.
Presence of silica flour can adjust the phase transformations and inhibit this strength reduction and the associated increase in permeability that occurs in set cement.

Why are the grinding stone wheels of a flour mill regularly taken out and the grinding surfaces are made rough?
The grinding stone wheels of a flour mill are regularly taken out and roughened to maintain their efficiency in grinding grains. Over time, the surfaces can become smooth due to wear, which reduces their effectiveness in crushing and grinding. By making the surfaces rough again, the friction increases, allowing for better grinding performance and producing finer flour. This process ensures consistent flour quality and maximizes the mill's productivity.
