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

摘要

The authors describe the additional requirements toensure durability of concrete related to probability of corrosiondue to alkali-silica reactivity of aggregates based on French Rulesfor Design and Construction of PWR nuclear civil works RCC-CW.Since these requirements are based both on European standardsand the French experience they are not fully compatible with theconditions and requirements in other countries, including Poland.In the paper the RILEM methodology and assessment accordingto American ASTM standards are presented as well. The articleis an introduction to the discussion on adapting to Polishconditions the guidelines for the reactivity assessment ofaggregate for concrete resulting from RCC-CW.
