it depends on when you buy your ticket. if you buy it early, you will get a cheap price if you buy it late you will get an expensive price
Depends on where in Europe, and number of stops/ route taken. Typically 10.5 hours or more for Paris France.
Portland, Maine? About 3 hours.

Yes, Paris has airports, so you can fly there direct from many parts of the world.
I assume you are contrasting portland cement with fly ash to portland cement with powdered slag? (Fly ash is from coal furnaces, powdered slag is from oil-burning furnaces). Slag is very similar to portland cement, and can be used to cheaply replace up to 50% of portland cement in concrete. This is less expensive, and the slag makes the hardened concrete more resistant to de-icers. Fly ash is not similar to portland cement, but is also good to resist de-icers. But since fly ash is not similar to portland cement, only 20 to 30% of portland cement can be replaced by it. The main difference in chemistry are the amounts of oxygen-containing elements. (Called 'oxides'). For example, portland cement has 65% of C2O, Slag cement has 45%, and Fly ash contains 25% For SiO2 portland cement 20%, Slag cement 33%, and Fly ash 37% For Al2O3 portland cement 4%, Slag cement 10%, Fly ash 16%. There are other very minor differences in chemistry.
