Determining the reactivity of concrete aggregates for Nuclear Power Plant concrete structures

The authors describe the additional requirements to
ensure durability of concrete related to probability of corrosion
due to alkali-silica reactivity of aggregates based on French Rules
for Design and Construction of PWR nuclear civil works RCC-CW.
Since these requirements are based both on European standards
and the French experience they are not fully compatible with the
conditions and requirements in other countries, including Poland.
In the paper the RILEM methodology and assessment according
to American ASTM standards are presented as well. The article
is an introduction to the discussion on adapting to Polish
conditions the guidelines for the reactivity assessment of
aggregate for concrete resulting from RCC-CW.
