From a table in another chapter, I see that the early compressive strength (MPa) of 42,5N at two days is about 10 MPa and 42,R about 20 MPa. Both reach between 42,5 and 62,5 after 28 days. In the chapter on highperformance concrete, it states that substituting about 8% of the cement with condensed silica fume "could enhance strength".

Megapascals to kilopascals [MPa to kPa] conversion tables
How to convert megapascals to kilopascals [MPa to kPa]:. p kPa = 1 000 × p MPa. How many kilopascals in a megapascal: If p MPa = 1 then p kPa = 1 000 × 1 = 1 000 kPa. How many kilopascals in 41 megapascals: If p MPa = 41 then p kPa = 1 000 × 41 = 41 000 kPa. Note: Megapascal is a metric unit of is a metric unit of pressure.
