High limestone content in cement: An important step ...

Adapted concrete technology. Durability is a crucial quality feature of concrete and an important requirement for sustainable constructions. Investigations have shown that the disadvantages of high proportions of limestone in the cement regarding concrete durability can be compensated to a large extent with a denser microstructure by reducing the w/c ratio.
